In 2014, the price of a WiFi connection module was more than 60 yuan; In 2018, the price of WiFi connection module was made in 9.9 yuan RMB by Xiaomi.

As a microcosm, this sharp reduction in hardware costs often means that the IoT industry is entering the growth period from the pioneering period, from small-scale exploration attempts to large-scale experience replication. At this stage, the expansion scope and expansion speed per unit time have become the core indicators for players in the industry to compete. For Xiaomi, building a larger connection and making AI ubiquitous will help him win this competition.

Constructing a complete "three-ring" layout is the need for Xiaomi to establish a larger-scale connection faster. The innermost ring of this model includes Xiaomi’s core products such as mobile phones, televisions, boxes, routers and smart speakers. The middle link is the IoT ecological chain system built by Xiaomi through investment incubation; The outermost ring will be a third-party manufacturer accessing the Xiaomi IoT system. Its advantage lies in that it can export the IoT ecological capacity quickly cultivated by the inner ring and the middle ring to the outermost ring.

On the basis of the "three-ring" layout, with the increasing number of connected devices, Xiaomi can realize the ubiquity of AI voice assistants, and with this advantage, it can integrate content and services, achieve a breakthrough in the field of Internet services, and help Xiaomi become a veritable "Internet company". Even when Xiaomi AI voice assistant occupies the user’s mind, the potential energy of this AI+IoT will have the opportunity to make Xiaomi the underlying foundation in both C-end and B-end markets.

This is also the ambition of Xiaomi’s "AI+IoT" strategy: on the one hand, it is possible to connect as many smart devices as possible to realize the ubiquity of Xiao Ai’s classmates; on the other hand, through this ubiquitous advantage and the cultivation of users’ voice interaction habits, it will become the ultimate integration and presenter of content and services, and finally improve the commercial ecological construction of hardware+Internet services and break the inherent stereotype of "hardware companies".

Open the ecological chain and build a larger connection.

As the mobile phone market enters the stage of stock competition, the new incremental market of IoT is becoming a new battlefield for mobile phone manufacturers. Looking for the next growth point, this encounter in the IoT industry has a more important significance for mobile phone manufacturers, that is, mobile phone manufacturers have the opportunity to become the leader of new connection establishment on a larger scale by virtue of their natural advantages in the IoT hardware field, thus having more voice in the AIoT era.

For this reason, Xiaomi founder and CEO Lei Jun said at the "MIDC·2018 Xiaomi AIoT Developers Conference" that in the next 5 to 10 years, AI+IoT will be the core strategy of Xiaomi. In establishing the connection between things, things and people, Xiaomi, which has an early layout, mature ecology and determination, has a certain first-Mover advantage, but it also needs to break through the misunderstanding that people can’t access the Xiaomi IoT system without joining the Xiaomi ecological chain, and show a more open Xiaomi, and make the outermost part bigger and bigger.

"Xiaomi’s investment is only to promote and strengthen this cooperation more effectively. This is what I want to explain to you today. Xiaomi’s determination to open up has not changed. I hope everyone can understand this." Lei Jun stressed. In his view, all giants are extremely optimistic about the AIoT industry, and the competition is becoming more and more fierce, which also requires Xiaomi to be more open than before.

On the basis of early exploration, sharing Xiaomi’s experience and ecological environment with more third-party manufacturers, helping them to complete the intelligentization of products more efficiently, and accessing more IoT systems with more users is the key for Xiaomi to lead the connection in the future. With the demand of users pushing more and more hardware manufacturers to seek the intelligence of hardware products, it is obvious that the way of ecological chain can no longer meet the pursuit of speed and scale.

From the data point of view, the "enclosure movement" in the IoT market has just begun. According to iResearch data, in 2017, the global market share of consumer-grade IoT hardware accounted for 1.7%, followed by Apple 0.9%, Amazon 0.9%, Samsung 0.7% and Google 0.6%. Although Xiaomi’s Q3 financial report in 2018 shows that the number of IoT consumer-grade IoT connected devices in Xiaomi has reached 132 million (excluding mobile phones and laptops), compared with the 15.3 billion IoT device connections predicted by iResearch in 2022, there is also a big gap.

In the past year, Xiaomi IoT platform has accessed more than 1,000 third-party products. During the developer conference, Xiaomi announced a cooperation with IKEA. Starting from December, all intelligent lighting products of IKEA will be connected to Xiaomi IoT platform, which can be controlled by Mijia and Xiaoai. In terms of connection technology, Xiaomi not only made the WiFi module RMB in 9.9 yuan, but also began to support the connection between ZigBee and Bluetooth Mesh.

Not only Xiaomi, but also BAT, Huawei and OV are striving for more third-party hardware access to their own IoT ecosystem. By introducing small speakers with obvious price advantages, Baidu has caught up with Xiaomi in the sales of smart speakers in the third quarter, with more than 300 DuerOS partners and more than 160 landing master devices equipped with DuerOS. The partners of the HiLink smart home platform established by Huawei have already included brands such as Opal, Jiuyang, Midea, Cobos, Bull, Haier, Boss and Iflytek.

According to an employee of a third-party manufacturer at the developer conference, Xiaomi’s advantage over other manufacturers lies in its ability to bring goods. Xiaomi itself has a large number of users with strong scientific and technological attributes, and is willing to try new things such as IoT devices. At the same time, Xiaomi also has its own new retail channels, which helps to help new products be quickly recognized by more users. "In e-commerce channels other than products, users often find our products by directly searching for product names instead of product categories, which has a lot to do with crowdfunding on products."

"In addition to providing developers with embedded software solutions, networked intelligent modules, unified APP experience and intelligent linkage, and reliable cloud services, we actually provide developers with new retail channels for incubating their own brand products — — Xiaomi has a product. " These tools in Fan Diankou, general manager of the IoT platform department of Xiaomi Group, are the chips for Xiaomi to break out of the eco-chain model and go to more third-party manufacturers, and are also the key to winning the advantage in the connection agreement dispute.

Get through three big rings, AI is everywhere.

The establishment of more connections not only won the dominance of IoT connection agreement for Xiaomi, but also provided the foundation for Xiaomi to promote its AI voice assistant service to more users. In Xiaomi’s explanation of "AI+IoT strategy", open cooperation is a key word, which allows more devices to access Xiaomi’s IoT system and improve the "three-ring" layout; Core competence is also a key word, that is, to realize the communication of the three rings and jointly accomplish the goal of making Xiao AI’s AI ability ubiquitous.

"I believe that control technology such as AI+IoT will be embedded in every device in the future. There may not be a special device called smart speaker, or smart speaker will become a very small device. This technology is embedded in every device." Lei Jun said that in three to five years, every smart device may have the control module of AIoT, which will make the whole interaction very interesting.

What is interesting is that the intelligent voice assistant will become a powerful AI capability system, which is both an open platform and a strong ecology. One end of this system will be connected with all kinds of intelligent hardware, while the other end will be connected with content and services. In the middle, a well-run skill developer ecosystem is needed to develop different capabilities for this system and effectively connect hardware with content and services. On the basis of full hardware connection, voice assistant will become the ultimate integrator of hardware, content, service and AI technology.

"Xiaomi has a very deep layout in both mobile phones and IoT. It is based on the advantages of these Xiaomi on the end and based on the mature AI advantages, we feel that Xiaomi is standing on a bigger cusp today." Cui Baoqiu, vice president of artificial intelligence and cloud platform of Xiaomi Group, said.

In order to grasp this enthusiasm, Xiaomi provided Xiaoai students with the opportunity to run on other brands of Android phones and Apple phones by releasing Xiaoai students’ App+ Bluetooth devices separately. On the other hand, Xiaomi tried to integrate the content and function with Xiao Ai’s classmates, breaking the boundaries between the inherent apps, and cultivating users’ habits to directly summon content or services through Xiao Ai’s classmates.

In Cui Baoqiu’s introduction, there are now more than 200 smart devices that can support Xiao Ai’s control in 23 major categories, and this number is still growing at the rate of four (models) every Wednesday. At the same time, Xiao Ai also supports calling Microsoft Xiao Bing, and Xiaomi IoT system also supports connecting with Google Assistant and Amazon Alexa.

The simultaneous opening of the IoT system and AI capabilities has improved the speed of Xiaomi’s connection with IoT hardware, expanded the coverage of Xiaoai students, and accelerated the pace of Xiaomi’s integration of hardware, products, content and services.

"We should not only connect with smart device manufacturers, but also connect with Internet manufacturers. We should connect with APP developers of software and hardware, as well as skill developers. We should access AI technology companies and hope that various companies can help us provide services. We will fight for the world. In the end, all the green users in the upper layer will be served. Our users of Xiaomi are also users of everyone, and we are users together. " Cui Baoqiu said.

Users wake up and execute a specific function on mobile phones and intelligent hardware devices through voice commands, and behind this function are capability developers. These capability developers can independently choose which way their capabilities are carried by APP, applet or light application according to their needs. By connecting scenes and services, the AI voice assistant has presented the possibility of becoming a new front entrance, providing more imagination for Xiaomi.

Down-to-earth, longing for the starry sky

On the basis of the establishment of a wider range of connections, Xiaomi will be able to build a system including hardware, content and services: that is, Xiaomi takes IoT hardware as the carrier and implants its own AI capabilities into more hardware products by exporting its own hardware ecological chain capabilities; Then, with the ubiquitous AI voice assistant as a new entrance, more content and services are included in the ecology to realize the integration of hardware, content and services. Even, on the basis of this system, we have embarked on a bottom-up road of smart city construction.

Keeping the mobile phone business in the competition in the stock age, relying on users and ecological foundation to maintain its own advantages in the IoT market, and further strengthening the technical ability in AI, so that Xiaoai students can truly be everywhere, is the field that Xiaomi needs to step on in the C-end market, and the foundation of becoming a solution integrator.

If this attempt can be successful, it means that in the C-end market, a considerable number of users will choose to use Xiaomi’s intelligent hardware products to realize voice interaction through Xiaoai students, and at the same time, they will accumulate a large number of user data and ability developers with Xiaoai students. This accumulation is equally important for B-end users, which will make it possible for Xiaomi to March from the C-end market to the B-end market.

The cooperation between Xiaomi and All Seasons Hotel shows the possibility of expanding from C-end to B-end. At present, through this cooperation, Xiaomi has moved scenes such as small love speakers and intelligent lighting to the upcoming all-season Shanghai Hongqiao Center Hotel, where customers can experience Xiaomi’s smart home while traveling or on business, and play a role as a model room. When the users of IoT devices and Xiaoai classmates reach a certain number and become more and more dependent on voice interaction, it may become an inevitable user demand for hotels to install smart homes carrying Xiaoai classmates.

This will be a B-side change triggered by the accumulation of individual user needs. When Xiaoai students are ubiquitous, Xiaomi IoT system, which also grasps hardware, users, content and services, will also be able to extend to the depth of the industrial chain and undertake more service and management needs of B-side users.

"We have so many smart devices and have a good platform. Let’s start from this point. We will expand it from an individual user to a family, then expand it to the whole building and then to the community. Finally, through this platform, we will gradually make a real smart city." Wang Yulin, CEO of Jinshan Cloud, said.

Whether To C or To B, Xiaomi urgently needs to break out of the pattern of ecological chain and build a complete "three rings". On the basis of large-scale hardware equipment connection, it will complete its own ecological construction with the help of the potential energy of AI+IoT, so as to prepare for the coming AIoT era.

Because the competition in the AIoT era is destined to be a competition between different ecosystems, Xiaomi needs a complete ecology as a ticket for the final competition.

　　Xi ‘an, Central Broadcasting Network, September 10th (Reporter Zhang Wei Shu Longhuan) The reporter of Central Broadcasting Network learned today (10th) from the zhenba county Emergency Management Bureau of Hanzhong City, Shaanxi Province that on September 9th, the landslide in zhenba county caused the interruption of National Highway 210, and one person was injured and one trapped person was successfully rescued.

　　A landslide occurred at the Dahekou at the junction of Yanchang Town and Yudu Town in zhenba county (video screenshot from Yangguang. com)

　　Affected by four rounds of heavy rainfall since July, at about 18: 30 on September 9, 2021, a landslide occurred at Dahekou at the junction of Yanchang Town and Yudu Town in zhenba county, which interrupted the 210 National Road and blocked the Yushui River, injuring one person and trapping another. The injured people were immediately sent to the hospital for treatment, and were diagnosed with leg and rib fractures. The condition was stable and the mood was stable; The trapped people were successfully rescued at 7 am on September 10, and their vital signs are normal at present.

　　The collapse of the mountain caused the water in Yushui River to be blocked (photo courtesy of local people from Yangguang. com)

　　After the dangerous situation occurred, the local government departments attached great importance to it, and departments such as emergency, public security, transportation, water conservancy, health, natural resources and fire rescue rushed to the scene to rescue, set up an emergency rescue headquarters, and set up seven working groups including comprehensive coordination, on-site rescue, medical treatment, traffic control and personnel evacuation to carry out emergency rescue and disposal work.

　　Traffic control is implemented in collapsed sections (photo courtesy of local traffic police issued by Yangguang. com)

　　At present, the National Highway 210 has implemented traffic diversion control, and is carrying out personnel arrangement for village groups around landslides. The personnel in upstream and downstream risk areas have been fully and rapidly transferred, and rescue materials, rescue equipment and other transportation and storage work have been put in place, and rescue work is being carried out in an orderly manner.

　　At the same time, zhenba county conducted a comprehensive investigation and risk assessment of geological hazards, promptly eliminated all kinds of safety hazards, and ensured the safety of people’s lives and property.

　　"I’d rather never touch ‘ Dark net ’ It is too late to regret it now. " He Shi (a pseudonym), a 30-year-old Hainanese, got the court’s verdict at Hai ‘an Detention Center in Jiangsu. In July last year, he was arrested by Jiangsu police for drug trafficking, and was later sentenced to two years in prison and fined 10 thousand yuan.

　　He Shi said in an interview that it was the "dark net" that made him break through the moral bottom line.

　　The "dark net" refers to the hidden network, which ordinary netizens can’t search and access by conventional means, and they need to use some specific software, configuration or authorization to log in. Because the "dark net" has the characteristics of anonymity, it is easy to breed all kinds of illegal crimes with the network as a linking tool, and some young people are deeply involved. China Youth Daily China Youth Network reporter’s online search of China’s judgment documents shows that there are 21 cases involving "dark network", involving criminal acts such as drug trafficking, spreading pornographic and terrorist illegal information, and infringing citizens’ personal information.

　　It is noteworthy that with the increasing number of people visiting the "dark net" in China, the group of young people is expanding, and even minors are involved. In recent years, criminals use the "dark net" to commit crimes increasingly. The public security organs continue to study the illegal crimes related to the "dark net", strengthen the crackdown on the "dark net" crimes, and urge the relevant units to strengthen the network security protection work and block the security risks from the source.

　　"Although ‘ Dark net ’ It has the characteristics of anonymity and concealment, but ‘ Dark net ’ Not ‘ Extralegal land ’ And ‘ A sin-free paradise ’ 。” Wang Yingwei, director of the Network Security Bureau of the Ministry of Public Security, said at the press conference of the Ministry of Public Security a few days ago.

　　Use bitcoin to buy drugs in the "dark net" and sell them at a high price in China.

　　Around 2014, He Shi liked to soak in foreign website forums and inadvertently learned about the "dark net". As a network maintenance major, he is full of curiosity. Through a series of operations, he saw a network world different from ordinary cognition.

　　"Gun trafficking, drug trafficking, organ trafficking, bloody video … … Although I don’t know whether it is true or not, the evil of human nature is vividly displayed on it. " He Shi said that this is a network world with high freedom and extreme things and non-extreme things coexist. At first, he just browsed some new things on it and never thought of using it to do anything else.

　　Later, after reading foreign novels, he noticed that a famous writer mentioned in the book that LSD had brought them infinite inspiration. "I especially want to know what it feels like." He Shi said.

　　The scientific name of LSD is ergot diacetamide, which is a strong semi-artificial hallucinogen. Although all the publicity I came into contact with said that drugs were harmful to people, in these books, He Shi saw the magical effect of "creating technological upgrading". "This subverts my perception of drugs."

　　He Shi wants to start with LSD first. In 2018, he contacted a Polish through the "dark net" and paid in bitcoin to buy more than 200 drug "stamps" with a unit price of LSD as the main component in 30 yuan.

　　"The color is disordered and the time and space are reversed. It seems that I have experienced several lives and spent three lives." He Shi described the feeling of smoking "stamps" when interviewed by China Youth Daily and China Youth Network. He thought that this hallucinogenic drug was not addictive and harmless.

　　He Shi realized that "stamps" have a big market in China. Not long after, he quit his original job in real estate sales, and contacted overseas sellers on the dark internet to buy "stamps", and contacted domestic buyers through WeChat and the Internet to sell the "stamps" received at the price of RMB from 160 yuan to 200 yuan.

　　The "dark net" has become a hotbed of crime.

　　The reporter of China Youth Daily and China Youth Network entered the keyword "dark net" in China Judgment Document Network, and found 21 cases. Among them, there are 8 cases of smuggling, trafficking, transporting and manufacturing drugs, and 7 cases of infringing citizens’ personal information, 3 cases of illegal possession of articles promoting terrorism and extremism, and 1 case of other three types of crimes, namely kidnapping, destroying computer information systems, and making, copying, publishing, selling and disseminating obscene articles for profit.

　　In September 2018, the People’s Court of Anyuan District, Pingxiang City, Jiangxi Province publicly pronounced the first case of infringement of citizens’ personal information in Pingxiang. The defendant purchased citizens’ credit card information through the "dark net", then bound the mobile phone payment and stole the credit card to obtain illegal benefits. The court sentenced two defendants to fixed-term imprisonment and fined hundreds of thousands of yuan for the crime of infringing citizens’ personal information.

　　In June this year, the People’s Court of Luoping County, Yunnan Province also announced a case of using the "dark net" to infringe citizens’ personal information. The defendant posted on overseas websites, indicating the service items and prices of citizens’ personal information such as personal household registration, family household registration, house opening records, and living together records, and traded in bitcoin in the "dark net" market. From April to November 2018, more than 1,000 pieces of personal information of many people were illegally obtained and sold, with a profit of 1.33315 bitcoin, and 1.30948 bitcoin was converted into RMB 41,397.35.

　　The verdict shows that after the defendant claimed that he was deceived in finding a job, he came up with the idea of "making money by providing personal information online". Most of the information he sells is sent to the other party through Chinese forum network and dark goods trading market, and some of it is sent to the other party through social software. The information mainly includes personnel tracks, room opening records, mobile phone account opening information, etc. Among them, the highest price is mobile phone positioning information, and the lowest is household registration information.

　　In addition, obscene and violent videos in dark networks are also common. A case decided by the People’s Court of Pingyi County, Shandong Province shows that the defendant learned, downloaded and exchanged obscene and violent video files through the "dark net" and spread them to three people for profit.

　　According to a network technology practitioner, due to the anonymity of access, the encryption of information and the concealment of servers, the "dark network" soon became a new channel for criminals to engage in illegal and criminal activities after 2004. In addition to illegal trade in prohibited goods, illegal information such as pornography, kidnapping, assassination and terrorism is also extremely rich, and it has even become an important platform for terrorist organizations.

　　The "dark net" is not illegal.

　　According to public information, on April 30 this year, the largest "dark net" market "dream market" was closed. On the same day, law enforcement agencies from Europe, Canada and the United States launched operations and announced that international law enforcement agencies had arrested 61 people, closed 50 dark online accounts for illegal activities, and executed 65 search warrants, seizing 2,995 kilograms of drugs, 51 guns and more than 62 million euros.

　　According to public information, since the beginning of this year, public security organs across the country have filed 16 cases related to "hidden networks" and arrested 25 suspects involved in illegal and criminal activities involving "hidden networks", of which two have been sentenced to fixed-term imprisonment and 23 have been detained in criminal detention.

　　With the increasing number of people visiting the "dark net" in China, the group of young people is also expanding. "Dark network" has become a new field of cyberspace governance in China, and the crime of "dark network" has also brought new challenges to cyberspace governance.

　　Jin Ming, deputy squadron leader of the Seventh Squadron of the Criminal Police Brigade of the Public Security Bureau of Hai ‘an City, Jiangsu Province, said that there are many difficulties in cracking down on the crime of dark network in terms of system and technology, so the effectiveness of the crackdown in various countries is also uneven. Due to the cooperation between network and logistics, drug-related crimes have become more professional, and drug traffickers are at a low age and tend to be professional. The borderless network inevitably requires countries to strengthen international cooperation in law, system and technology, seize key links, bring criminals to justice, and prevent the "dark network" from becoming an extra-legal place.

　　Dr Ni Jun, from the Institute of Cyberspace Strategy of Fudan University, wrote that China should further study and carry out governance measures that are in line with China’s national conditions on the basis of learning from the experience and practices of foreign "dark network" governance. Relevant government departments should organize domestic key cyber security research institutes to carry out research on special projects, so as to have the "dark network" management and control technical ability to meet the needs of cyberspace governance in China as soon as possible.

　　Lawyer Fan Guomin of Jiangsu Nuofa Law Firm pointed out that it is difficult to obtain evidence for "dark net" crimes, which makes it more difficult for law enforcement agencies to crack down on crimes. It is suggested to improve the ability of obtaining evidence through various technical means. In addition, the state should establish cooperation with some enterprises involved in network security, jointly develop technologies and tools, and let some professional technicians participate in specific actions to control "dark networks".

　　He also suggested that it is necessary to strengthen the implementation of relevant laws and regulations, eliminate the black and gray industrial chain of making and selling fake ID cards, black phone cards, fake IDs, etc., and the public security and network information departments jointly launched a special "dark network" crackdown to increase the monitoring and crackdown on "dark networks" and the use of "dark networks" to commit crimes.

　　Aspect: GPGPU processor developed by Denglin Technology adopts software and hardware co-design and will be used by customers for testing at the end of this year.

　　Lead: The new concept of "AI chip" has gradually gone through the stage of popularization in the past year and is more and more familiar to the public. In the process that the industry has gone through barbaric growth and started to accelerate its landing and integration, more AI chip companies have also begun to step out of their own differentiated routes.

　　After the first season of previous AI chip series reports, Zhidongxi set out again, and further conducted differentiated in-depth follow-up reports on nearly 100 core enterprises in the whole AI chip industry chain. This is one of the second seasons of the series of reports on the AI chip industry in Zhidongxi.

　　When it comes to universal AI chips, no one will ignore NVIDIA.

　　With the super parallel processing capability of GPU, NVIDIA got on the high-speed train of artificial intelligence (AI), and in recent years, its market value soared by more than ten times, making it invincible in the field of AI chips in data centers and becoming an unshakable cloud AI overlord.

　　The outbreak of computing power provides the cornerstone for the accelerated development and landing of AI technology. The hot AI market has spawned a number of emerging AI chip entrepreneurs at home and abroad.

　　In the past, chip giants such as NVIDIA and Intel dominated the cloud AI market, and most AI chip startups chose to avoid its edge and specialize in the field of terminal AI-specific chips.

　　However, one company named "Denglin Technology" has a unique vision, aiming at GPGPU, which is now controlled by NVIDIA. GPGPU is the full name of general purpose computing on graphics processing unit, that is, a graphics processor (GPU) capable of general computing. It extends the application scope of GPU beyond graphics, and has been widely used in large-scale parallel computing in scientific research, education, financial computing, industry and other fields.

　　At present, only NVIDIA has realized the large-scale commercialization of GPGPU in the world, and the gap in this field in China is still obvious, but several players have been working hard to develop it.

　　▲ Li Jianwen, founder and CEO of Denglin Technology

　　On a warm morning, Zhi Dongxi chatted with Li Jianwen, the founder and CEO of Denglin Technology, to see how this veteran who has been deeply involved in GPU for 20 or 30 years led the team to develop innovative GPGPU architecture with versatility and high efficiency, and moved towards the vision of "becoming the NVIDIA of China".

　　GPU veterans have been in business for a year and a half, and more than a dozen patents are in hand.

　　As the mainstay of AI development, the opportunities for the underlying hardware of AI are undoubtedly extremely broad, but looking around, most of the solutions for cloud AI training in the world are provided by American company NVIDIA.

　　The design of high-performance processor is facing many challenges such as high complexity, technical difficulty and deep technical barriers. It is a key field in the field of integrated circuit design, and the relevant talent pool is very limited, even in Silicon Valley, where many IC elites gather.

　　Li Jianwen studied in Tsinghua University Institute of Microelectronics with a bachelor’s degree, and obtained a master’s degree from the Circuit Teaching and Research Group of Tsinghua Radio Department in 1990.

　　As early as 2017, Li Jianwen began to think, why don’t we build Chinese’s own server AI chip?

　　This idea became the bud of Li Jianwen’s founding of Denglin Technology.

　　Before the establishment of Denglin Technology, Li Jianwen had twenty or thirty years’ experience in GPU field. He served as the vice president of TUxin Technology (founded in 2004), and the GPU/GPGPU IP products he was in charge of were sold to famous semiconductor and technology companies such as Freescale, Intel, Meiman, Google, Samsung, Nokia and Dahua.

　　At first, Li Jianwen was also attracted by Google TPU, and wanted to have a try on special AI chips. However, during his time as a consultant of Northern Lights Venture Capital, Li Jianwen found that in the face of the rapid evolution of algorithms and the emergence of new applications, the special AI chip similar to Google TPU does not have the versatility needed by the market. Maybe after investing a lot of money and time to make the chip, the market no longer needs this thing.

　　After seeing the bottleneck of dedicated AI chip, based on years of accumulated industry experience, Li Jianwen is determined to make some achievements in the construction of heterogeneous general computing platform with GPGPU as the core, and make GPGPU solutions with better performance than NVIDIA.

　　In November 2017, Li Jianwen established Denglin Technology in Shanghai, which was hatched by the well-known high-tech venture capital institution "Northern Lights". The Angel Round and Pre-A Round of financing were completed at the end of 2017 and the first half of 2018 respectively, with a total financing amount of about 150 million RMB.

　　The core founding team of Denglin Technology consists of eight people, seven of whom have been deeply involved in the GPU field for a long time, and one has rich experience in network processors.

　　According to Li Jianwen, other members have worked for many years in world-renowned semiconductor, system and Internet companies such as TUX, NVIDIA, AMD, Cisco and Acacia. Each member not only has more than 20 years’ experience in high-tech industry, but also has the achievements of successful streaming and mass production in advanced technology from 28nm to 7nm, and comprehensively covers the parallel processor system architecture, software and hardware, core IP, processor verification platform construction, and the development of the overall SoC chip.

　　After a year and a half of development, there are about 60 people in the company now, most of whom have at least a master’s degree, no less than 78 years of work experience and very rich industry experience. At present, Denglin Technology has obtained more than a dozen patents, and dozens of core patents are being applied at home and abroad.

　　Software and hardware combined with innovative GPGPU will be delivered to customers at the end of this year.

　　With NVIDIA GPGPU Zhuyu in the front, if a startup wants its products to be recognized by the market, it usually chooses to cut prices and earn less money.

　　But Li Jianwen wants to do more than that. He hopes to do something different. He can not only inherit the advantages of NVIDIA, but also be as good as NVIDIA’s GPU in universality. At the same time, he has made some innovations in technology, which makes the calculation density higher, the efficiency further improved, and the demand for external bandwidth greatly reduced.

　　In people’s traditional cognition, NVIDIA’s GPGPU core is mainly oriented to graphics acceleration and high-performance computing, but in order to take into account the characteristics of all these applications, his hardware structure is fixed, the execution mode is based on instruction set, and the storage is centralized data storage based on the traditional von Neumann architecture, which limits the efficiency of hardware to some extent and is not the optimal solution for AI applications.

　　Therefore, Li Jianwen chose to adopt the concept of software and hardware co-design in the system architecture design, so as to solve the problem of both universality and high efficiency of AI computing.

　　Different from the customized AI processing chips provided by other manufacturers, the "boarding -Minsky" architecture (software-defined heterogeneous AI computing platform) independently innovated by Denglin Technology has higher flexibility in architecture design.

　　The software can predict the final application of customers. Through feature analysis at a higher application level, various hardware designs including pipeline, control model and storage model can be optimized according to the characteristics of tasks.

　　Through this architectural innovation, Denglin Technology can make the computing density and efficiency of AI processor hardware higher, the power consumption and area lower, and the requirements for bandwidth are much lower.

　　"It turns out that it’s like handing over the task to the right hand after the left hand has done something, and the way of software and hardware collaboration is that the two hands work together." Li Jianwen vividly metaphor.

　　According to him, compared with Tesla V100 and Tesla T4, the latest mainstream products in NVIDIA, the products of Denglin Technology have improved their performance by 5-10 times on the basis of lower-cost mature technology and reducing the chip area by more than 50%.

　　At the same time, it is unrealistic for a startup company to re-create a set of software ecology directly before it grows up. Therefore, Li Jianwen chose to inherit the ecology with NVIDIA as the main body and provide better solutions.

　　Li Jianwen revealed that the GPGPU processor at the core of Denglin Technology has passed the FPGA verification, and the design of the first generation product Goldwasser has also been completed, which is being fully verified before streaming. The product is planned to be available for customer testing before the end of this year.

　　Startups need to see three directions clearly.

　　Li Jianwen believes that it is very important for a new company to understand three aspects: one is the market, the other is the technology and product route, and the third is that the market and technology direction should be consistent with the team’s ability.

　　First of all, the AI hardware market is developing rapidly, which is recognized by everyone. According to the report of American research institute Tractica, by 2025, the market of cloud AI chips is expected to reach $14.6 billion.

　　At this time, the choice of technology and product route is particularly important. Because the iteration speed of the current AI algorithm is still very fast, Li Jianwen thinks that the risk of developing a special AI chip will be greater. Relatively speaking, the route of a general AI chip is more secure and feasible.

　　Even if you see the market opportunity and find the potential technology and product direction, you need to have the ability to be good at this field. Similarly, taking Denglin as an example, most of their members have mature experience in the GPU field, and they have practitioners with excellent professional and technical skills from software and hardware, IP to SoC, so they have the ability to solve problems quickly and develop products.

　　Previously, with the increasingly hot AI chips, a large number of fans poured into this market. However, as the capital market became calm, people began to question whether there was a bubble behind this carnival.

　　For this phenomenon, Li Jianwen thinks that the market is a little overheated. Some people and capital who jumped in underestimated the difficulty of cloud AI processors, but PPT can’t make chips. The ultimate winner must be someone who can have a deeper understanding of customers’ ideas and make products that truly solve customers’ core problems.

　　Conclusion: The landing tide of large-scale AI chips has not yet arrived.

　　Last year, it can be said that the domestic and international science and technology circles were involved in a frenzy of AI chips. Both traditional semiconductor companies and AI chip entrepreneurs stood their ground, and various cloud computing companies, AI algorithm companies and traditional industry giants poured in across borders, vying to announce their own research on AI chips.

　　They chose different technologies and product paths to meet the needs of different application scenarios such as data center, security and voice.

　　According to the AI chip plans announced by various companies before, there will be a number of products of AI chip companies at home and abroad one after another this year and next. From the underlying hardware to the adaptive solutions, the competition in the field of AI chips will become more intense. The bursting of any bubble will be accompanied by the disappearance of a large number of start-ups, but after the strong wind blows, the start-ups that really grasp the market needs and solve customer problems will stand out.

　　　　　　 The film "New king of comedy", directed by Stephen Chow and starring Wang Baoqiang and E Jingwen, has been scheduled for release on New Year’s Day. On January 24th, Wang Baoqiang came to Hengdian with New king of comedy and visited the gathering place of extras. At the meeting, Wang Baoqiang connected the "drifting" family on the spot, hoping that the family would give them more encouragement and support, and encouraged the "drifting" people. "Although the process will be cruel, as long as you work hard and don’t surrender, you will be successful!"

　　When Wang Baoqiang came to Hengdian this time, he recalled his career as an extra actor. He admitted that it was Yin Tianchou in king of comedy that supported him through the years of "walk-on". This year coincides with the 20th anniversary of the release of king of comedy, and I hope that the new king of comedy starring myself can bring some spiritual strength to today’s "drifters".

　　At the first stop of Hengdian, Wang Baoqiang came to the training room of the Actors’ Guild to cheer up the new people who just came to Hengdian to be actors, share their experiences, and sent the first introductory lesson to pursue their dreams. "At first, it was the hardest. Without fame, we had to rely on our own efforts". Recalling his own struggle process, Wang Baoqiang said: "I am often hungry, but even if I am hungry, I have to print materials and run the crew." Facing the new "drifters", Wang Baoqiang said that he kept telling himself that the word "the masses" would be removed from the actors one day, and finally he succeeded.

　　Wang Baoqiang also rushed to Hengdian Film and Television City, the shooting base, to give red envelopes and send blessings to the "drifting" who went to work. The "drifting" people are scrambling to learn from their predecessors. A "drift" who has been in Hengdian for seven years said: "I haven’t called home for a long time, for fear that my family won’t support me." Wang Baoqiang bluntly said: "You should always call your family to let them know that you are safe outside, and the encouragement and support of your relatives can make you go further and better." In the connection with another "drifting" relative, Wang Baoqiang said: "I hope you can give him more encouragement and support, and I hope that one day he can bring you a better life through his own efforts." Wang Baoqiang also said: "The walk-on road is very difficult, and many people don’t understand and support it. You can take your family and friends to the cinema to watch" New king of comedy "on the first day of the New Year’s Day, which is your hardship and difficulty. I believe that through intuitive understanding, your family and friends will feel your efforts and value."

　　"Laughing with tears" is a major feature of Stephen Chow’s comedy films, and the struggle history of little people is the core of his films. Wang Baoqiang said: Although this is a "walk-on movie", no one is a small role. Everyone is a real actor and has their own bright spots. "This story is about the struggle of ordinary people. I believe everyone will get some positive and positive feelings, which can also bring you a lot of confidence and strength."

　　China Daily Online, September 21st According to comprehensive US media reports, the US Congress is moving towards the possibility that the government will shut down as early as next month. At present, there is no indication that the persistent differences between the two parties on the budget issue will end soon. At the same time, according to a report on the US Capitol Hill website on the 20th, the funds for an American Affordable Connectivity Program (ACP) aimed at ensuring that all Americans can connect to the fast Internet, thus narrowing the "digital divide" are expected to run out in the spring of 2024.

　　Kathryn de Wit, the author of the article and director of the broadband access project of Pew Charity Trust Fund, pointed out that the two parties must find opportunities for cooperation without delay and bring tangible benefits to the public. One of the important projects is the ACP project, which was previously supported by politicians and voters of both parties. If the funds of this plan are allowed to dry up, millions of low-income families will suddenly lose the network connection that they now rely on for work, school and medical treatment. If the plan is stopped, the pockets of at least 20 million Americans will be immediately affected.

　　According to previous reports, the United States has been monitoring the calls of European leaders all the year round, and the military leak incident has also exposed the large-scale monitoring of its allies by the United States, and it is even more "not to mention" to obtain user privacy data on social networks. The United States has a bad track record in the field of network security, and the "matrix" and "network hegemony" are worthy of the name. According to the data of the Federal Communications Commission, there are 8.5 million "unserved" areas and 3.6 million "underserved" areas in the United States.

　　If the US Congress does not continue to provide funds for ACP after next spring, it means that the promise of broadband access in the Bipartisan Infrastructure Construction Act and other federal broadband plans will be broken, and the progress made over the years will come to nothing. According to a survey by the Digital Progress Institute, a bipartisan NGO, 78% of Americans support continuing to fund the program. But Congress did little to ensure that the plan continued.

　　The New York Times reported on 19th that the lack and uneven distribution of high-speed Internet had a great impact on American people’s study, work and life. The article writes that due to the lack of high-speed internet service, residents in the southeastern edge of Oklahoma are distressed every day. Wanda Finley, a resident of Sawyer, the state, is a fourth-grade teacher. She said that the satellite service at home is often too slow to use, and sometimes it is even interrupted for several days. Before going to work, she can’t arrange medical appointments, apply for prescription refills or pay bills online. Almost every weekend, she has to drive to school for about 40 minutes to prepare lesson plans, because the internet speed at home can’t be loaded at all.

　　The lack of broadband infrastructure is particularly serious in rural areas of the state, where Internet services are usually unavailable or limited. According to the definition of the new plan, about 24% of Americans in rural areas lack high-speed Internet service, while the proportion in urban areas is only 1.7%.

　　However, Evan Feinman, director of the National Telecommunications and Information Administration’s $42.5 billion project (ACP), said that they believe that federal and state funds will be enough to cover every unserviced and underserved area.

　　For Americans who lack high-speed internet access for a long time, the coverage of this fund will be crucial. Finley said that she wanted to assign more online research assignments to speed up her study. But among the 20 students in her class, only three students have enough internet access at home, and the rest can’t finish it.

　　A few miles away, there are about 600 residents in Towsenburg, Oklahoma. The mayor Tami Barnes said that the slow internet speed has had a "great impact" on the local economy. Although online bills have added a burden to many families, if there is a high-speed internet, more residents may see a doctor through the internet, instead of spending three hours to see a specialist.

　　Other states with low population density, such as Montana, may also face more challenges. In broadwater County, Montana in the northwest, many families are separated by large grasslands, while others are located in mountainous areas. Residents say it is difficult for them to work from home because of the lack of quick service. In southeastern Florida, many people still lack reliable broadband access. The U.S. Census Bureau even pointed out that among the 10 counties with the lowest per capita income in the state, 7 counties have the lowest broadband access rate. According to recent data, the number of registered ACP programs in Florida is about 1.4 million, accounting for 38% of eligible families in the state.

　　According to the related report of The Minnesota Daily)19 website on 19th, most of the courses of the University of Minnesota are completed through Canvas, which requires the internet to access. Students who live in the campus can use the free network of the university, but many students who live in off-campus dormitories cannot access the internet, and the internet cost is very high.

　　According to the data of American Midwest Higher Education Compact, 16% to 19% of students lack Internet-related assets. Baraka Aswan, a sophomore who lives off campus, said that they had considered reducing water and electricity bills through the ACP plan. Aswan shared a room with friends. He said that in the first week of college, his house could not use any wireless network, which made their first few days back to school very difficult. Aswan added that cheaper Internet can leave more room for other expenses such as groceries and rent.
