Overlooking China Yagu Science and Technology Park.

Ziyang speeds up the cultivation of industries with distinctive advantages such as food and beverage.

The first toothed rail train "Snow Mountain Brigade" produced by CRRC Ziyang Locomotive Co., Ltd. in China will be used in the mountain rail transit project from Dujiangyan to Siguniang Mountain.

Spring is full of vitality. Entering Ziyang, there is a vigorous vitality of development and enterprising everywhere.

On March 1st, Ziyang held the ceremony of "Cloud Signing" for industrial investment projects, and signed 18 key projects on site with an investment of 4.918 billion yuan. Twenty days ago, at the cooperation meeting of "State-owned enterprise Ziyang Bank" project in 2023, Ziyang and state-owned enterprises "joined hands" and signed 18 projects, with a total cooperation amount of 47.6 billion yuan …

Projects attract frequent actions, and the pace of seizing opportunities for development is also accelerating. The first Chinese New Year tea party for entrepreneurs, leading cadres at the municipal level and leading comrades at the county level studied and implemented a series of activities such as the Party’s 20th Spiritual Reading Class, studied and implemented the decision-making arrangements of the CPC Central Committee and the provincial party committee, and gathered consensus on development; The city’s industrial high-quality development conference and Ziyang High-tech Zone, Ziyang Airport Economic Zone high-quality development conference, the municipal party committee rural work conference and a series of meetings, special deployment of relevant work arrangements.

From the meeting place to the market, from planning to action, an agreement with wet ink, and a project site in full swing-Ziyang, which is struggling to write a new chapter in building socialist modernization in an all-round way, is moving steadily.

The Sixth Plenary Session of the Fifth ziyang Municipal Committee and the Economic Work Conference of the Municipal Party Committee made it clear that it is necessary to do a good job in promoting the development of Ziyang High-tech Zone and Ziyang Airport Economic Zone, implementing the strategy of strengthening the city through industry, deepening the "three major events" of the reform of municipal state-owned enterprises, implementing the "three major battles" of industrial projects, traffic construction and urban planning and construction, deepening the "n reforms" of state-owned enterprises, and speeding up the construction of a modern industrial new city in Chengdu metropolitan area and a demonstration zone for the rise of central Chengdu and Chongqing.

Stepping into a new journey, Ziyang is striving to embark on a road of modernization that grasps the general trend of the times, embodies the characteristics of Ziyang and serves the overall situation of the province.

Grasp the strategic opportunity and lead the modernization development.

On February 24th, at the construction site of the starting point of the shield section from Lingkong Economic Zone Station to Jiaozi Avenue Station on Ziyang Line of rail transit, two shield machines were started at the same time, and the belt conveyor made a "squeaking" sound, dozens of workers were working, and the muck in the tunnel was continuously transported outside.

"Project construction is accelerating." Tian Li, deputy commander of Ziyang Line Command of Rail Transit, said that at present, all stations on the rail line are capped, and the work of erecting beams on the elevated section has also come to an end. By the end of the year, the whole line of bridges and tunnels will be completed.

As the first cross-city intercity rail transit line in the province, the Ziyang line of rail transit will be pulled into the same city and enter a new stage of "rail city" after its completion.

In the past year, a number of transportation infrastructure projects have blossomed in Ziyang, focusing on the urbanization of Chengzi and the construction of the twin-city economic circle in Chengdu-Chongqing area: Chengdawan, Chengdu-Chongqing middle line and Chengziyi high-speed railway have been substantially promoted, Chengzi Avenue has been completed and opened to traffic, and Ziyang-Tongliang (Sichuan border) expressway has started construction …

The promotion of transportation infrastructure has opened up the "big channel" and also brought big projects: in Ziyang Airport Economic Zone, the construction of Ziyang Fangte Cultural Tourism Project has been accelerated, which is expected to attract millions of tourists from the province and even the whole country; In Lezhi County, the site construction of Fenan Aluminum Southwest Base is in full swing, and it will become a highland for the development of local intelligent manufacturing industry in the future; In Anyue County, the new project of Ziyang Gas Power Station of Sichuan Investment Group is carried out in an orderly manner. After the whole project is put into operation, it is estimated that the annual power generation will be 7 billion kWh, which can be used by 3 million families …

Ziyang has made it clear that it will adhere to the construction of the twin-city economic circle in Chengdu-Chongqing area as the general traction, promote high-quality development with the strategic support of the integration of capital into the same city, and accelerate the construction of a modern industrial new city in Chengdu metropolitan area and a demonstration zone for the rise of central Chengdu-Chongqing area.

The relevant person in charge of Ziyang Municipal Committee said that with the urbanization of capital and the construction of the twin-city economic circle in Chengdu-Chongqing area, various undertakings in Ziyang have opened up a new situation and entered a critical period of breakthrough and an opportunity period of high-quality development.

This point has been deeply felt by many people who are struggling in the front line. Zhong Ning, deputy general manager of CITIC Construction Co., Ltd. and chairman of Sichuan Ziyang Airport Industrial New Town Construction and Development Company, mentioned a change in attracting investment: compared with a few years ago, entrepreneurs who came to contact no longer asked questions about infrastructure construction, but consulted specific matters such as labor costs and upstream and downstream industrial chains around their own development. "This shows that enterprises have begun to consider the situation after landing, which reflects that the attractiveness of capital contribution to enterprises is increasing."

Focus on key breakthroughs and drive overall improvement.

On February 22nd, Ziyang held the city’s industrial high-quality development conference and the high-quality development conference of Ziyang High-tech Zone and Ziyang Airport Economic Zone.

One will focus on industrial development and the other will focus on regional development. Why should they be held together? The answer is "promoting the overall improvement through key breakthroughs".

The relevant person in charge of Ziyang Municipal Committee further explained: from the perspective of industrial development, industry is the main engine of modern industries, and it is necessary to concentrate resources to drive industrial breakthroughs with industrial development and achieve overall economic improvement with industrial breakthroughs; From the perspective of regional development, Ziyang High-tech Zone and Ziyang Airport Economic Zone are the main positions of Ziyang’s industrial development. The development of the two zones should drive the all-round development of the city and achieve the effect of "revitalizing all at once".

Accelerate the construction of a modern industrial system with industry as the main engine, and provide strong industrial support for accelerating the construction of a modern industrial new city in Chengdu metropolitan area and a demonstration zone for the rise of central Chengdu-Chongqing area. Ziyang has a clear path-we should focus on "three major events", implement "three major battles" and deepen "n reforms".

More expectations are also brewing. Tang Yiting, deputy director of ziyang Economic and Information Technology Bureau, said that the local government is promoting industrial clusters and industrial agglomeration, and accelerating the construction of a modern industrial system focusing on industries with distinctive advantages. In promoting major projects, Ziyang will promote the start of 14 projects such as the southwest production base of keeway electric vehicles, accelerate the construction of 17 projects such as the southwest base of Fenan Aluminum, and complete and put into operation 9 projects such as the expansion of auto parts in Gillista; In terms of strengthening industrial clusters, Ziyang will focus on precisely attracting investment, extending the chain and supplementing the chain around characteristic and advantageous industries, and promote the formation of a 10 billion-level industrial cluster, so as to realize the total output value of seven major industries, including medicine and health, equipment manufacturing, energy and chemical industry, with a scale of more than 45 billion yuan …

The shock has come, and everything is revived. On both sides of the Tuojiang River, projects have been accelerated and industrial clusters have taken shape … A new picture of Ziyang’s modernization full of vitality has been quietly unfolded. (Reporter Li Wei Gao Kun/Wen Hua Xiaofeng/map)

For four and a half months

Fishing season in East China Sea

Has already begun.

In 2024, the marine summer fishing moratorium system continued the management regulations in 2023, and continued to uniformly implement the fishing moratorium in the East China Sea from 12: 00 on May 1 to 12: 00 on September 16. Tens of thousands of fishing boats in Zhejiang Province fully entered the moratorium period.

Specific types of banned sales and

What are the prohibited places?

Let’s take a look ↓↓

According to the relevant regulations, from May 8 to August 1, it is forbidden to sell eight kinds of marine chilled or live aquatic products, such as hairtail, large yellow croaker, small yellow croaker, silver pomfret, mackerel, Portunus trituberculatus, dragon head fish and shrimp, in various trading places such as farmers’ markets, supermarkets and temporary stalls, as well as restaurants and food stalls.

Four types of fishing boats, such as shrimp trawling with truss, cage pot, gill net and light fence, were specially licensed to catch shrimps, crabs, pelagic fish and other resources on August 1. After August 1st, Zhejiang residents can buy seafood such as swimming crabs caught in the East China Sea in the market.

During the fishing moratorium, should Zhejiang people who love seafood say goodbye to seafood completely?

Cultured and imported seafood will take over the "baton" of local seafood fishing. Clams, clams, mussels, squid, sea urchins and abalone are all good choices to buy seafood at this time.

Aquatic products such as bass, snapper, grouper and American red fish from marine farms, as well as aquatic products imported from abroad and caught in the ocean, are not within the scope of the ban on fishing, which can make up for the vacancy during this period.

In addition, according to the Law of People’s Republic of China (PRC) on the Protection of Wild Animals and the Decision of the Standing Committee of Zhejiang Provincial People’s Congress on the Total Prohibition of Illegal Trading and Overeating of Wild Animals, market organizers such as commodity trading markets and farmers’ markets are strictly prohibited from providing display, trading and consumption services for illegally selling, buying, eating and using wild animals and their products or hunting tools that are prohibited from being used.

Market organizers should earnestly fulfill their main responsibilities, strengthen the study of relevant knowledge such as the fishing moratorium system and wildlife protection, carry out extensive publicity and education for business operators, strengthen the management on the market, and immediately stop illegal transactions in the market and report to relevant departments in a timely manner.

The market supervision department will strengthen the inspection and supervision of various markets in accordance with the law, carry out in-depth special law enforcement actions such as "Breeze Action" and "Zhijiang Sword", severely crack down on illegal sales of aquatic products and illegal wildlife transactions in the market, strengthen cooperation with forestry, public security and other departments, and promote the investigation and management of illegal transactions in a list and closed-loop manner.

Since 2010, the city has implemented the policy of free bus ride for the elderly over 65 years old, and more than 2 million elderly people in the city have enjoyed this benefit. This revision aims at the problems that the elderly in other places can’t ride for free, and the use of the car-respecting card is inconvenient, and further improves the free ride policy for the elderly, making the policy more inclusive and meeting the travel needs of the elderly groups more accurately.

In view of the problem that the elderly people from other places can’t ride free of charge, after the policy adjustment, the elderly people who are registered in this city, those who live in other places in this city and those who come to Tianjin temporarily can enjoy free ride benefits, which further expands the inclusive scope of the policy and implements the relevant provisions on the protection of the rights and interests of the elderly people in the country, so that all elderly people in Tianjin can enjoy free ride benefits.

In view of the inconvenience of using the card for respecting the elderly by car, after the policy adjustment, the elderly registered in this city and the elderly from other places holding the residence permit in this city can choose the third generation social security card, the card for respecting the elderly and the electronic card for riding for free; Old people who come to Tianjin temporarily can apply for a temporary electronic card and a temporary card to ride for free. The richness of free ride media provides a variety of choices and channels for the elderly to better meet the needs of different elderly groups.

In addition, after the policy adjustment, the elderly are encouraged to travel in peak hours and enjoy a safer and more comfortable ride environment, so as to reduce potential safety hazards and relieve the pressure of morning and evening peak rides.

　　Since the beginning of the year, the renovation of the old housing area in Gulou District has been reported frequently:

　　Three old renovation projects started at the beginning of the year, such as the renovation of the old housing area around Xianta Street, the plot around Fuda Yishan Campus (I) and the Guoyangdang plot, have basically completed the relocation;

　　The requisition and relocation of four contiguous old housing reconstruction projects, including the reconstruction project from Ouyechi to Chenghuang Temple (Phase I) and the reconstruction project around Huoxiang, are progressing in an orderly manner;

　　Two old housing reconstruction projects, including Sheshan in Mei Feng, are about to enter the site, and another eight projects are in the early stage of preparation, and the land requisition and relocation will be started in due course in the second half of the year.

　　The renovation of old housing areas bears the people’s dream of living in peace, and is also closely related to the improvement of urban functional quality. In order to speed up the construction of a blessed state with a more beautiful environment, better quality, more comprehensive functions and better service, last year, the municipal party committee and the municipal government decided to implement a three-year action plan for the renovation of contiguous old housing areas, and put forward the specific deployment of the "three-year action plan and two-year work arrangement".

　　Gulou District attaches great importance to it, responds quickly and takes the initiative to pressurize it. It has decided to start all the 17 450,000-square-meter old renovation projects involved in the "Three-year Action Plan" within this year. "Three-year old reform, one-year implementation", in this tough battle, the majority of cadres in Gulou District lifted their spirits, worked hard, carefully planned and coordinated, collected sunshine and provided sincere service, and carried out the action of "improving livable environment and building a happy home" in depth, striving to show new responsibilities and achieve new achievements in the new era.

The "Carp Jumping at the Dragon Gate" water feature of the four-story fountain, and the rockery waterfalls built by the real mountains are cut off … This is not a star-rated hotel in a metropolis, but a newly-built middle school in Zhen ‘an County, Shangluo City, a deep poverty-stricken county in Shaanxi Province. And there are more doubts behind this "luxury middle school".

Generally speaking, schools that are beautiful or even gorgeous will not be questioned too much. After all, "no matter how poor you are, you can’t be poor in education". However, according to a survey conducted by Xinhua Viewpoint, the local fiscal revenue of Zhen ‘an County in 2019 was less than 200 million yuan, and the total investment of this middle school was as high as 710 million yuan, which led to high debts, which made people not only confused about whether it was an "image project" variant under the "luxury" appearance, but also suspected that some school leaders’ office buildings exceeded the standard.

"luxury" campus in poverty-stricken counties: it costs more than 2 million yuan to cut mountains and fake waterfalls, and the area of several leading offices is suspected to exceed the standard.

In order to solve the problem of insufficient degree in urban areas, since 2015, Zhen ‘an County has started to build a new Zhen ‘an middle school project. The new campus is located in Taiping village, Yongle street, Zhen’ an county, about 14 kilometers away from the county seat, and has been delivered recently. According to the school, the school covers an area of 272 mu, with a total construction area of 129,000 square meters, and plans to accommodate 6,000 students.

The reporter recently visited the site and found that there are 24 main buildings such as teaching building, dormitory building, dining building, gymnasium and teachers’ apartment in the new site of Zhen ‘an Middle School, and 120 classes are set up, which greatly improves the educational conditions in mountainous areas.

However, there are some facilities that have nothing to do with teaching in the campus: entering the campus from the magnificent antique archway gate, the four-story fountain waterscape ascending the steps along the trail, 16 stone carvings of carp distributed on both sides, and the school motto marble tablet about 8 meters long and 1.5 meters high on one side is located at the end of the fountain. According to the staff of the school, the waterscape means "carp jumping at the dragon gate", and the school motto stone tablet pulled from Xi ‘an cost 50,000 to 60,000 yuan.

Passing through the huge square arch of the school administration building, the pyramidal roof with triple eaves and the library based on the Hall of Prayer for the Good Year in the Temple of Heaven are built on the high platform. There are some reading rooms in the building, but the space utilization rate is low. There is only one sand table in the large high school.

On campus, except for the stone railings that can be seen everywhere, every building has an imitation Tang-style building roof. In the southwest corner, a pavilion is built on a multi-level waterfall group with a length of about 50 meters and a drop of about 15 meters, surrounded by rockeries, waterwheels, plank roads, waterscapes and stone arch bridges.

According to the relevant person in charge of the preparation office of Zhen ‘an Middle School, the water features of rockery waterfall cost more than 2 million yuan, and for this reason, some mountains were leveled and anti-landslide retaining walls were built. The affiliated projects of the whole school, such as green belt and pipe network, cost more than 80 million yuan.

The internal facilities of the administrative office building are also quite eye-catching. The visual area of the office with the number of "Deputy Secretary" is more than 30 square meters, and the visual area of another office with the sign of "Director of Class Management Office" is about 30 square meters.

According to the Construction Standard for Office Buildings of Party and Government Organs, the area of county-level deputy offices of county-level organs shall not exceed 24 square meters. As a deputy county-level unit, Zhen’ an Middle School has obviously exceeded the office area of "Deputy Secretary" and "Director of Class Management Office".

In addition, in the school dining room with a total area of 14,000 square meters, there are several private rooms on the fourth floor, with mahogany floors, chairs with flowers and exquisite tableware.

A cadre of Zhen ‘an County Party Committee said that the reason why the campus should be built with Tang-style architecture style is because the local government wants to build Tang Wenhua to "promote the integration of culture and tourism".

Last year, the local fiscal revenue was only 178 million yuan, and it was necessary to repay more than 50 million yuan in loans every year for 12 consecutive years.

As early as February 2013, the Ministry of Education issued the Notice on Building an Economical Campus through Diligence and Thrift Education, proposing that school buildings should be built according to the principles of simplicity, practicality, applicability and resource conservation, and the cost standards of school building construction projects should be strictly controlled, and luxury decoration should not be allowed, and "luxury school gates" and "luxury office buildings (rooms)" should be resolutely put an end to.

The Opinions on Further Adjusting and Optimizing the Structure to Improve the Efficiency in the Use of Education Funds issued by the General Office of the State Council in August 2018 clearly states that education should be carried out with diligence and thrift, image projects and achievements projects are strictly prohibited, and luxury schools are strictly prohibited from being built beyond the standard. Every education fund should be used in key places. We should do our best, do what we can, and not engage in the project of "living beyond our means".

According to the reporter’s investigation, the total investment of Zhen ‘an Middle School Project is 710 million yuan, and Zhen ‘an County needs to repay at least 50 million yuan in loans every year for 12 consecutive years.

According to the relevant person in charge of the school preparation office, the Zhen ‘an Middle School project started in 2015, and the preliminary expenses such as land demolition, three links and one leveling, planning and design cost 90.8 million yuan. Subsequently, Zhen ‘an State Investment Corporation and the contractor jointly invested more than 100 million yuan to set up a project management company, and raised 320 million yuan from the bank, making up 510 million yuan of the total investment in the project budget.

"In the past few years, the final settlement cost has changed again, and the current investment has reached 710 million yuan." The person in charge said that in addition to the estimated annual repayment of 53.37 million yuan to the bank for 12 consecutive years, there are still about 200 million yuan in arrears. "In the future, the county will take part of the money, and then find ways to win the higher-level funds to solve part of it."

As a deep poverty-stricken county that took off its hat in May 2019, in 2019, Zhen ‘an County completed local fiscal revenue of 178 million yuan, and public budget expenditure mainly relied on fiscal transfer payment. Zhen ‘an County’s "Report on the Implementation of the Budget in 2019 and the Draft Budget in 2020" shows that in 2019, "the task of preventing and resolving government debt risks is arduous, and the debt repayment pressure is increasing". From January to May 2020, the county’s local tax revenue reached 60.81 million yuan, down 7.2% from the same period of last year. According to the report, in 2020, "the government debt service will surge, and the contradiction between revenue and expenditure will become more acute".

Beware of the spread of luxury and livelihood projects

In the interview, some local cadres believed that building schools with high standards reflected the concept of "no matter how poor you are, you can’t be poor in education", even if you build them ahead of time, it is understandable. However, some experts say that it sounds like a good thing to borrow money to run a school, but in fact, a lot of funds are not really used to improve teaching, which leads to a waste of funds, formalism and a distorted view of political achievements.

Some teachers in Zhen ‘an Middle School reported that while the hardware was improved, the software such as school teachers’ strength was not significantly improved. Moreover, some planning is unreasonable, resulting in a waste of resources.

According to the data of the school, there are four teacher apartment buildings in the school, of which 104 are two bedrooms, one living room, one kitchen and one bathroom, and 334 are one bedroom and one bathroom. All the apartments are "Simmons, wardrobes, bookcases, sofas, tables and chairs, dining tables, stoves, sanitary baths and TV broadband, and you can check in directly with your bag".

However, many teachers report that most teachers live in the county town and will not move in, which may cause apartment buildings to be idle. Moreover, the new school is 14 kilometers away from the county seat, and the monthly commuting expenses will be more than 1,000 yuan, which increases the burden on teachers.

Shi Ying, vice president of the Chinese Society of Social Sciences and head of the People’s Livelihood Group of the Shaanxi Provincial Decision-making Advisory Committee, said that it is understandable that the school is ahead of schedule, but the school is not a scenic spot, so it is unnecessary to build antique buildings and rockery waterfalls beyond its actual value.

Some experts said that the original intention of attaching importance to education in poor areas is worthy of recognition, but we must do what we can. Especially after the wind stops in the building, it is necessary to prevent the wind of luxury from spreading to people’s livelihood projects. While improving the educational hardware, the government should also invest in the construction of teaching staff and personnel training.

The highlight of NPU(AI chip) and GPU (common chip) is that they can run multiple parallel threads. NPU takes it to another level through some special hardware-level optimizations, such as providing some easily accessible cache systems for some truly different processing cores. These high-capacity cores are simpler than the usual "conventional" processors because they don’t need to perform many types of tasks.

On July 20th, CAMBRIAN was officially listed in A-share science and technology innovation board, becoming the first AI chip, which aroused heated discussion and concern in the industry.

According to relevant data, there are more than 1,500 IC design enterprises in China. However, there are fewer companies with AI chips, and there are only more than 20 companies. Among these AI chip companies, CAMBRIAN is the most prominent, especially the recent IPO, and the stock of Kechuang soared on the first day of listing. So what is AI chip, and how is it different from our ordinary CPU?

From the perspective of principle logic, AI processor is a special chip, which combines artificial intelligence technology and machine learning, making the mobile device of the chip smart enough to imitate the human brain, which is used to optimize the work of deep learning AI, and is also a system using multiple processors with specific functions. The ordinary chip (ordinary cpu) is packaged in a smaller chip package, which is designed to support mobile applications and provide all the system functions needed to support mobile device applications.

Most of the time, the marketing teams of major companies find the word AI (artificial intelligence) very "advanced and gorgeous", so they bind it to almost any possible commercial use. So, you must have heard of it

"Artificial Intelligence Chip" is actually a renamed version of NPU (Neuroprocessing Unit). These are special types of ASIC (Application Specific Integrated Circuits), which are designed to widely apply machine learning in the mobile market.

These ASIC have a special architecture design, which enables them to execute the machine learning model faster, instead of unloading data to the server and waiting for its response. This execution may not be so powerful, but it will be faster because there are fewer obstacles between the data and the processing center.

Generally speaking, we can understand that NPU is AI chip and ordinary chip is CPU.

The CPU will work well in a general load environment, because it has a high IPC, which can be executed through many serial ports. And the CPU follows the Von Neumann architecture, and its core is to store programs and execute them sequentially. The architecture of CPU needs a lot of space to put storage unit (Cache) and Control unit (control unit). Compared with it, the computing unit only occupies a small part, so it is extremely limited in the ability of large-scale parallel computing and is better at logical control.

The highlight of NPU and GPU is that they can run multiple parallel threads. NPU takes it to another level through some special hardware-level optimizations, such as providing some easily accessible cache systems for some truly different processing cores. These high-capacity cores are simpler than the usual "conventional" processors because they don’t need to perform many types of tasks. This whole set of "optimization" makes NPU more efficient, which is why so much research and development will be invested in ASIC.

Machine learning model processing requires CPU, DSP, GPU and NPU to be synchronized at the same time, which is because many chip processing units are working together. But it also explains why such execution is "heavy" for mobile devices.

One of the advantages of NPU is that most of the time is focused on low-precision algorithms, new data flow architecture or memory computing power. Unlike GPUs, they are more concerned with throughput than latency.

Of course, AI algorithm is very important. In image recognition and other fields, CNN convolution network, speech recognition, natural language processing and other fields are commonly used, mainly RNN, which are two different algorithms. However, in essence, they are all multiplication and addition of matrices or vector, and then cooperate with some algorithms such as division and exponent.

In addition, a mature AI algorithm is optimized for specific mathematics of convolution operation and weighted summation. This process is very fast. It is like a GPU without graphics hardware. For the AI chip, if the specific target size is determined, then the total number of multiplication and addition calculations is determined. For example, a trillion times, for example, if I run a program with an AI chip, I can have a meal, and the CPU needs to run for several weeks. No commercial company will waste time.

In addition to the CAMBRIAN, there are also these well-known AI chip companies in China, such as Bitcontinent, Horizon, Tianxin Zhixin, Yizhi Electronics, Exploration Technology, Suiyuan Technology, Hisilicon, Jianan Technology, etc., all of which have experienced the actual landing inspection period from 2015 to the present, before they get to the present situation. The products of each company are also unique, with their own styles in power consumption, performance and application scenarios, which can occupy a place in the vast market of China.

China AI chip company is in a development boom. What about the development of foreign AI chips? Now let’s look at the companies that we think are the top developers of artificial intelligence chips, although there is no specific order-just those companies that have demonstrated their technology and have put it into production or will put it into production soon. The details are as follows:

1. Alphabet (Google’s parent company)

Google’s parent company urges the development of artificial intelligence technology in many fields, including cloud computing, data centers, mobile devices and desktop computers. Perhaps the most noteworthy is its Tensor Processing Unit, which is an ASIC specially designed for Google’s TensorFlow programming framework, mainly used for two branches of AI, machine learning and deep learning.

Google’s Cloud TPU is used in data centers or cloud solutions, and its size is equivalent to a credit card, but the Edge TPU is a coin with a size less than one cent, which is specially designed for some specific devices. Nevertheless, analysts who observe this market more closely say that Google’s Edge TPU is unlikely to appear on the company’s own smartphones and tablets in the short term, and it is more likely to be used in higher-end, enterprise and expensive machines and equipment.

2. Apple

Apple has been developing its own arm chips for many years, and may eventually stop using suppliers such as Intel. Apple has basically got rid of the entanglement with Qualcomm, and it really seems determined to go its own way in the field of artificial intelligence in the future.

The company uses A13 "bionic" chips on the latest iphone and ipad. The chip uses Apple’s neural engine, which is part of the circuit and cannot be used by third-party applications. A13 bionic chip is faster and consumes less power than the previous version. According to reports, A14 version is currently in production and may appear on more mobile devices of the company this year.

3. ARM

The chip design produced by Arm (ArmHoldings) has been adopted by all prominent technology manufacturers including Apple. As a chip designer, it doesn’t make its own chips, which gives it some advantages, just like Microsoft doesn’t make its own computers. In other words, Arm has great influence in the market. The company is currently developing artificial intelligence chip design along three main directions: Project Trillium, an "ultra-efficient" and scalable new processor with the goal of machine learning applications; Machine learning processor, which is self-evident; Arm NN is the abbreviation of neural network, which is a processor for processing TensorFlow, Caffe is a deep learning framework, and there are other structures.

4. Intel

As early as 2016, according to the Wall Street Journal, the chip giant Intel announced the acquisition of the startup NervanaSystems, and Intel will acquire the company’s software, cloud computing services and hardware, so that the products can better adapt to the development of artificial intelligence. But its artificial intelligence chip series is called "neural network processor": artificial neural network imitates the working mode of human brain and learns through experience and examples, which is why you often hear that machines and deep learning systems need "training". With the previous release of Nervana, it seems that Intel will give priority to solving problems related to natural language processes and deep learning.

5. Nvidia (NVIDIA)

In the GPU market, we mentioned that GPU can handle artificial intelligence tasks much faster than CPU, and Nvidia seems to be in a prominent position. Similarly, the company seems to have gained an advantage in the nascent artificial intelligence chip market. These two technologies seem to be closely related, and NVIDIA’s progress in GPU will help accelerate the development of its artificial intelligence chip. In fact, gpu seems to be the support of Nvidia artificial intelligence products, and its chipset can be called artificial intelligence accelerator. Jetson Xavier was released in 2018, and Huang Renxun, CEO of Jetson Xavier, said at a news conference: "This small computer will become the brain of future robots".

Deep learning seems to be NVIDIA’s main interest. Deep learning is a higher level of machine learning. You can think of machine learning as short-term learning with relatively limited data sets, while deep learning uses a large amount of data collected over a long period of time to return results, which in turn are designed to solve deeper and potential problems.

6. AMD (Ultramicro Semiconductor)

Like NVIDIA, AMD is another chip manufacturer closely related to graphics cards and GPUs, partly due to the growth of the computer game market in the past few decades and the growth of the bitcoin mining industry. AMD provides hardware and software solutions, such as machine learning and deep learning of EPYC cpu and Radeon Instinct gpu. Epyc is the processor name provided by AMD for servers (mainly used in data centers), while Radeon is a graphics processor mainly for gamers. Other chips provided by AMD include Ryzen, and perhaps the more famous Athlon. It seems that the company is still in a relatively early stage in the development of artificial intelligence-specific chips, but in view of its relative strength in the GPU field, observers believe that it will become one of the leaders in this market. AMD has signed a contract to provide Epyc and Radeon systems to the U.S. Department of Energy to build one of the fastest and most powerful supercomputers in the world, which is called "Frontier".

7. Qualcomm (Qualcomm)

Qualcomm made a lot of money from the cooperation with Apple at the beginning of the smartphone craze, and Qualcomm may feel left out in the cold about Apple’s decision to stop buying its chips. Of course, Qualcomm itself is not a small company in this field, and considering the future, it has been making some major investments.

Last year, Qualcomm released a new "cloud artificial intelligence chip", which seems to be related to its development in the fifth generation telecommunications network (5G). These two technologies are considered to be the basis for building a new ecosystem of self-driving cars and mobile computing devices. Analysts said that Qualcomm is a latecomer in the field of artificial intelligence chips, but the company has rich experience in the mobile device market, which will help realize its goal of "making artificial intelligence on devices everywhere".

Of course, other large international companies, such as Samsung, TSMC, Facebook, IBM and LG, are also developing their own AI chips. Whoever can master the cutting-edge AI chips first will get a slice of the new economic rising trend.

The reality described by the marketing departments of major companies is completely different from the reality outside those companies. Although decades of research have given us new ways to process information and classify input, which is faster than ever, there is no real AI in the hardware we buy, so which chip company can seize the market pain point and realize the application first, it can gain a great advantage on the track of artificial intelligence chips.

At present, the global artificial intelligence industry is still in a high-speed development, and the distribution of different industries provides a broad market prospect for the application of artificial intelligence. The commercialized society needs the application of artificial intelligence. AI chip is the hardware foundation for realizing the algorithm, and it is also the strategic commanding height of the future artificial intelligence era, and all the top companies in the world will fight for it. However, because the current AI algorithms often have their own advantages and disadvantages, only by setting a suitable scene for them can they best play their role. I also hope that AI can enter the sight of ordinary people this morning.

From the perspective of industrial development, it is still in the primary stage of artificial intelligence chips, and there is extraordinary room for innovation in both scientific research and commercial applications. In the application scenario, the AI chip with iterative algorithm develops into a general intelligent chip with higher flexibility and adaptability, which is the inevitable direction of technology development. Less computing bit width of neural network parameters, more customized design of distributed memory, more sparse large-scale vector realization, higher computing efficiency, smaller volume and higher energy efficiency in complex heterogeneous environment, the integration of computing and storage will become the main characteristics and development trend of artificial intelligence chips in the future.

　　Affected by the COVID-19 epidemic, the Geneva Motor Show scheduled to open on March 3rd was cancelled. The BMW i4 pure electric concept car, which was originally planned to be unveiled at the Geneva Motor Show, will be held online at 15:15 on March 3, 2020.

　　BMW i4 is positioned as an electric coupe. It is understood that BMW i4 will not have an independent electric car platform, but will be developed on the basis of the new generation of 3 Series (G20)/4 Series born from BMW CLAR platform, or adopt the design language of the new generation of 4 Series Gran Coupe. Mr. Adrian van Hooydonk, senior vice president of design of BMW Group, said: "The BMW i4 concept car extends electrification to the core of the BMW brand, and its design is dynamic, simple and elegant. In short, this is a perfect BMW that has achieved zero emissions. "

　　As the i4 whose product positioning is between i3 and i8, the appearance design of the new car is also between the two cars — — Not so sci-fi, and not completely succumbing to practicality. Or to put it bluntly, this car generally doesn’t look much different from the 4 Series — — It can also be understood that, after all, i4 can be regarded as an extension of the 4-series product line. However, as a pure electric vehicle, it is expected that the grille on the front face of i4 will not be too big.

　　At the rear, the new car seems to have some characteristics of BMW "GT" models. According to other information, i4 is expected to provide two driving forms: rear drive (i4 80 sDrive) and four-wheel drive (i4 80 xDrive), and the battery is also expected to provide 60 and 80kWh capacities. The fifth-generation pure electric vehicle technology adopted in this car will make the cruising range of this car between 550-700km.

Fast Technology reported on May 14th that Gary Black, a well-known Tesla investor and future fund management partner, released the data released by YipitDate, a credit card data provider.

The data shows that,Although Tesla American car owners experienced the FSD service for free during the trial period, only 2% car owners chose to continue to subscribe after the trial period ended, far below Blake’s expectation of 6%.

Blake also reminded that because the sample size is only 3,500, it may not fully reflect the wishes of Tesla owners. It is suggested that Tesla deeply analyze the reasons for the low acceptance rate, whether it is related to the added value of services or the pricing of 99 US dollars/month.

It is understood that Tesla’s self-driving products are divided into three levels:Basic AP(Autopilot), enhanced assisted driving EAP(Enhanced Autopilot), and the highest level FSD.

At present, AP is provided free of charge in China, and EAP costs RMB 32,000.The price of FSD in North America is $15,000 or $199 per month, and its functions include navigation-assisted driving, automatic lane change and automatic parking.

Since the FSD v12 version, Tesla has introduced the "end-to-end neural network", which controls cars by neural networks instead of traditional programming codes, and is praised by Musk as an innovation of "changing the rules of the game".

He predicted that,FSD will be updated every two weeks, and 26 version iterations will be realized every year, bringing 78 major improvements, which indicates a significant improvement in the security and functionality of FSD.
