This article analyzes with you "what is the current situation of domestic CPU development?" The content is detailed and easy to understand. Friends who are interested in "what is the development status of CPU in China" can follow the editor's train of thought to read it slowly and deeply. I hope it will be helpful to everyone after reading. Let's follow the editor to learn the knowledge of "what is the development status of CPU in China".

After the ZTE incident not long ago, national leaders put chips at the core of the development of China's information industry. no, no, no. It is well known that CPU represents the core technology of the chip, but in terms of CPU design, the gap between China and developed countries is still quite obvious. At the present stage, the architecture of CPU in China is roughly divided into MIPS system, x86 system, Power system, Alpha system and ARM system. Now the editor will take stock of the development status of domestic CPU!

1. MIP system:

1. Godson

Godson CPU is developed by Godson Research Group of Institute of Computing Technology, Chinese Academy of Sciences and developed by Shenzhou Godson Integrated Circuit Design Company authorized by Computing Technology of Chinese Academy of Sciences (the current Godson Zhongke Technology Co., Ltd.). At present, the main products of Godson are Godson No. 1, Godson No. 2, Godson 3A, and Godson 3B and so on. The frequency of Godson-1 is 266MHz, which was first put into use in 2002. The main frequency of Godson 2 is 1GHz, which is mainly used in low-end notebooks and some high-end embedded devices. Godson 3A series is a commercial 4-core processor with a main frequency of up to 1.5GHz and a power consumption of about 30W, which is more suitable for notebook chips. At present, the chips of domestic processors used by many party and government offices and some educational institutions are mainly Godson 3. The Godson 3B series is an 8-core processor that supports vector computing and has a peak computing capacity of 1.28 * 100 billion operations per second with a high power consumption ratio. It is suitable for high-performance computers and high-end servers. At present, Godson processors have been widely used in the army and some secret units, and its development prospects are still relatively optimistic. The instruction set of Godson is fully compatible with the instruction set of MIPS32 and MIPS64, and on this basis, Godson has developed its own instruction. At this stage, Godson has permanently bought out the authorization of MIPS instruction, which is completely autonomous and controllable from an autonomous and controllable point of view, and there will be no situation of being limited by others' necks in the future. At present, the development situation of Godson involves embedded, PC, and servers, but the market has not really opened. At present, the main market is still in the military and party and government office education and other fields, while the real civil market has not been involved, so if you want to develop and grow, the civilian market is a big piece of fat, as long as it can be hit, its sales can not be estimated. Of course, to open the civil market, the first thing to keep up with is the software ecology that accompanies the processor. At present, Godson does its own operating system and does the adaptation of the upper software with a number of software institutions, so the improvement of the software is very important to Godson. MIPS architecture compared with ARM architecture, software ecology is its congenital deficiency. Of course, the performance and stability of the processor are also very important. As long as the software can keep up with users and compete with window, the era of Godson is coming to replace x86.

2. Junzheng

Beijing Junzheng, like Godson, belongs to the MIPS camp. Unlike Godson, which focuses on embedded areas, Beijing Junzheng is a local IC design company focused on wearable, Internet of things. Because the software in the embedded field is generally customized according to demand, this leads to the specificity of some wearable products and applications in the intelligent wearable market, the relatively short software ecological chain, and the diversification of application requirements. Therefore, a set of general solutions can not be used to meet the needs of everyone. So it is impossible for a company to monopolize in this field. Therefore, it is not easy for PC and mobile phone market to be monopolized by X86 and ARM architecture in the smart wearable market. Smart wearable chips and Internet of things chips do not require high performance, most of the focus should be on low power consumption, low cost and size and other factors, so Junzheng's production fully meets its requirements. X86 processors cannot be used in this field, and IC design companies in the ARM camp are subject to high licensing fees, and do not have competitiveness in the market when the output of chips can not keep up, so for Junzheng, who has more than ten years of chip design experience and technology accumulation, the development in this field is still very objective. At present, it is widely used in the fields of smartwatch and smart home appliances in China.

Second, X86 system:

1. Public aspirations of Peking University

Beijing Beida Zhongzhi Microsystem Technology Co., Ltd., founded in 2002, is an important backbone enterprise in China's integrated circuit design industry. In 2005, AMD reached an agreement with the Chinese government, and the Ministry of Science and Technology formulated the Microelectronics Center of Peking University to accept the authorization of AMD Geode-2 processors. AMD is undoubtedly X86 architecture, so China has obtained x86 technology. However, Geode-2 belongs to the embedded processor of AMD, so Peking University Public Records also focuses on the embedded field. From the perspective of autonomous controllability, it does not belong to autonomous controllability. Once its authorization is stopped, it will be subject to the situation of being subject to human beings.

2. Megacore

Shanghai Zhaoxin is also a domestic chip design company with x86 architecture, which is already well known by many people. As we all know, the core technology of x86 architecture lies in the technology mastered by AMD and Inel, which will be strictly authorized by the US government. In addition to these two companies, VIA of Taiwan once licensed an x86 architecture. Mega core got the license from Intel, and on this basis developed its own ZX-C processor, and achieved mass production in 2015. 28nm quad-core processor, whose main frequency can reach 2G and supports national secret algorithm encryption, announced in 2017 that its new generation of ZX-D series 4-core 8-core processors have been successfully taped out. At present, the field of its use is mainly in the field of servers. Before the ZTE incident, its sales volume in the domestic circle was quite considerable, but after the ZTE incident, from the perspective of self-control, it was not controllable at all. Now in the domestic circle, the market share is gradually decreasing.

3. Haiguang

In addition to Shanghai Zhaoxin, Haiguang in Tianjin also belongs to a domestic chip design company with x86 authorization. In 2016, AMD announced an agreement with China's Tianjin Haiguang Investment Company to license x86 technology to Haiguang. The two sides will also set up a joint venture to license and produce server processors. It is said that in order to open up China's high-performance server market, AMD will license Haiguang's state-of-the-art x86 technology. At present, its performance is really good, but in the domestic circle, when using its products, it will still be estimated that it is not self-controllable.

3. Power system:

1. Zhonghao Hongxin

The Power architecture of IBM supported by Blue Giant has always been a high-performance endorsement. IBM established the OpenPower Open Alliance with NVIDIA and other companies in 2013, and other companies also obtained the authorization of Power architecture. Since then, it has also promoted China's Power technology industry alliance and signed licensing agreements with a number of companies. Zhonghao Hongxin is one of them. Zhonghao Hongxin was founded in 2013 and is currently in the domestic market. There is no shadow of its production. I believe that it will be able to see its production in the market in a few years' time.

Alpha system:

2. Shenwei

Shenwei processor or Shenwei CPU referred to as "SW processor", Shenwei continues to deepen and upgrade its own Alpha architecture, expanding the multi-core architecture and SIMD and other features of the extended instruction set on the basis of dual-core Alpha. Its production is mainly aimed at the field of high-performance computing services. At the 2016 International Supercomputing Conference, Shenwei Taihu Light supercomputer system based on Shenwei 26010 processor was unveiled and won the championship for the first time. Its peak computing power can reach 1.25: 10 to the eighth power of computing, making it the first supercomputer in the world to run more than 109 billion times. At present, in the server field, the application is relatively good, and its high performance and stability have been favored by the majority of users.

4. ARM system:

ARM system is believed to be the most well-known framework. At present, there are many companies authorized by ARM architecture in our country, but their authorization methods are different. ARM can be authorized in two ways, one is to authorize its "ARM processor IP" to partners, and partners can directly use its processor IP to design SOC chips. Another way of licensing is to license its "ARM architecture" to partners, who independently develop their processor cores based on ARM architecture. Then use the processor core to design the SOC chip. In the field of autonomous control, the company that directly obtains the IP of ARM processor does not belong to the company of independent controllable and independent research and development. At present, the main companies authorized by ARM architecture in China are Feiteng, Huawei's Hayes and Spreadtrum. The two companies are introduced in detail below.

1. Feiteng

Feiteng Company is an enterprise established by the high-performance processor research team of China University of National Defense Science and Technology, which has accumulated strong technical strength in the field of CPU for many years. Tianjin Feiteng unveiled the latest product FT2000 in 2016, which was first unveiled at the 2015 HotChips conference. The code name Mars is located in the high-performance server field. FT2000 uses the ARMv8 instruction set, but the use of self-developed kernel is different from the ARMv8 kernel on the market. The reason why FT2000 is remarkable is that its performance is really outstanding, including 64 FTC61 processor cores, and its published Spec2006 test results are very outstanding. This is the first time that the performance of domestic server chips has equalled that of Intel. At present, it has a good market share in the server field, and Godson is a hot independent controllable chip manufacturer at present. Feiteng has the inherent software ecological advantage of ARM architecture. At present, in the domestic circle, the market is still good.

2. Huawei Hayes

Huawei Hayes is currently one of the most technologically powerful chip developers in China. Huawei's Kirin chip is on a par with leading chip companies such as Qualcomm Samsung in performance. At present, its production is mainly used in mobile phone devices, the high-performance server field also has a good market share, and now it has to enter the domestic circle, which is undoubtedly not a bad news for other chip manufacturers in the domestic circle. Huawei's strength is obvious to all. At the 12th five-year Science and Technology Innovation Achievement Exhibition, Huawei displayed a server on the ARM platform, "Tarzan", equipped with an independently developed ARM64 architecture, "Hi612", which uses TSMC's 16nm process, has more than 16 cores and is compatible with the ARMv8 instruction set, which has achieved good performance. It is believed that Huawei's performance in this area will be more outstanding in the future.

3. Exhibition News

In addition to Huawei, Spreadtrum is another leader in domestic mobile phone chips. Spreadtrum shipped 670 million sets of chips in 2016 and announced the successful development of its own ARM processor in 2017, claiming that it has implemented a 6-core design on the same area of the SC9850 4-core (Context-A7) chip, and its power consumption and performance can be achieved according to its own configuration. It marks that Spreadtrum will become the second mobile phone CPU chip manufacturer with independent ARM architecture after Qualcomm besides Apple and Samsung smartphone manufacturers.

4. Huaxintong

In 2016, Qualcomm and Guizhou Zungu jointly funded a chip company, Huaxintong Semiconductor, which aims to design and develop server-specific chips for the Chinese market. Huaxintong has been licensed under the ARMv8-An architecture and has become the second big data central market in the world on behalf of China. This license will help Huaxintong launch advanced server design technology in the rapidly expanding CPC server market and help Chinese enterprises provide ARM-based server technology in their home market, thus promoting the large-scale deployment of efficient server solutions. At present, the market has not been opened, so we will wait and see how it will come.
