China s self developed CPU chip and its performance

First of all, let's talk about the domestic CPU Loongson on the PC side, Loongson is a general-purpose CPU independently developed by the Institute of Computing of the Chinese Academy of Sciences, using a simple instruction set, similar to the MIPS instruction set. Loongson 1 has a frequency of 266MHz and was first used in 2002. Loongson 2 has a frequency of up to 1GHz.

Loongson 3A is the first domestic commercial 4-core processor, which operates at 900MHz 1GHz. The peak computing power of the Loongson 3A reaches 16Gflops. Loongson 3B is the first domestic commercial 8-core processor, with a main frequency of 1GHz, support vector operation acceleration, and a peak computing capacity of 128Gflops, with a high performance-per-watt ratio.

However, there is still a very big gap between Loongson and the internationally renowned CPU manufacturers Intel and AMD.

As the world's leading ICT company, Huawei started the development of smartphone chips in 2006, and the K3V2 launched in 2012 is the earliest demonstration of the smallest quad-core processor, becoming the first domestic high-end smartphone chip with a scale of 10 million. The Kirin processor launched later fully adopts the SoC (System on Chip) architecture, that is, it integrates a complete system such as processor, communication module, audio decoding and peripheral circuits on a single chip. At the same time, Kirin adopts the current industry-leading 28nm HPM high-performance mobile process to meet the dual characteristics of high performance and low power consumption.

The soon-to-be-released HiSilicon Kirin 950 processor has caught up with or even surpassed internationally renowned mobile CPU brands Qualcomm, Samsung Exynos, NVIDIA, and MediaTek.

In addition to Huawei's HiSilicon Kirin, which has been put into use, the more well-known ones are MediaTek, Allwinner A10, Nufront, Rockchip, and Lianxin. Among them, MediaTek currently has a considerable share in the domestic low-end mobile phones, MediaTek mobile phone chips focus on low power consumption, so MediaTek's mobile phone chips are more power-efficient, and the performance is also relatively good.

You mean Loongson that garbage?

As we all know, the strength of a country depends on the efforts of a team of high-tech talents. The reason why the United States is so strong is, of course, that it has absorbed elites from all walks of life around the world to serve it, which is why the United States is so powerful today. It seems that technology is the master of the world.

Whoever masters the commanding heights of science and technology controls the world. As the United States exerts pressure on Huawei's restrictions, cutting off Huawei's chips around the world has made it difficult for Huawei. At the same time, it awakens our people and vows to be inspired.

It is the last word to make your own Chinese core. So which teams are making such developed chips in the United States? 1st place:

His name is Yang Peidong and he was born in 1971. He is a native of Suzhou, Jiangsu Province, China, and graduated from the University of Science and Technology of China and is currently the University of California.

Associate professor. It has achieved the world's first in the field of top chip materials. Second place on the list: Yin Yadong, a native of Jiangsu, also graduated from the University of Science and Technology of China, and now works at the University of California, Berkeley and the Lorenz Berkeley National Laboratory.

He then joined the University of California, Riverside, where he is now a tenured professor. This is Yin Yadong, the world's second largest nanomaterial. Third place: Professor Huang Xuanyi, born in Taiwan Province, China.

Graduated from New York, USA.

He is currently a professor at Tsinghua University in Taiwan Province. Among the six top scientists, he is the only one who is not a student who did not graduate from the University of Science and Technology of China. Ranked fourth:

Xia Younan, now a U.S. citizen, studied at Jingjiang Middle School in Jiangsu Province and was admitted to the University of Science and Technology of China with excellent results. At present, the United States is engaged in nanotechnology research, which has a great impact on the world. 5th place:

Sun Yugang, a student who walked out of the University of Science and Technology of China. Since 2006, he has been engaged in independent research at the Nanomaterials Research Center of Argonne National Laboratory in the United States, becoming a tenured researcher, and is also the main person in charge of the nanomaterials synthesis laboratory. He is unique in nanocomposites, which has deeply influenced the world and ranks among the top in the world.

Sun Yugang does not have much information on the Internet. In sixth place is Wu Yiying, who is still a Chinese citizen and a graduate of the University of Science and Technology of China. His specific information is unknown.

It is now The Ohio State University.

He is a tenured professor in the Department of Chemistry. Yiying Wu is mainly engaged in the synthesis and design of photoelectric conversion of solar cells, dye-sensitized cells and low-dimensional nanomaterials, and has achieved a large number of research results. He is a rare talent in today's world.

Strengthening the country in science and technology is fundamental. Only by retaining talented people can the motherland develop faster. I also hope that international students will succeed in their studies as soon as possible, return to the embrace of the motherland, and strengthen China.

It is believed that in the near future, this oriental lion will definitely stand at the forefront of the world.

Domestic chip design companies have developed rapidly in recent years, such as Loongson, Feiteng, Zhaoxin, Haiguang, and HiSilicon, which are currently excellent chip design companies. But if the development prospects are better, it is still Feiteng Company. Now many fields are using Feiteng chips to work.

Moreover, Feiteng has a complete product lineage, high performance, and a high degree of autonomy, especially in the performance of high-performance desktop CPUs, with annual shipments of more than one million pieces, and is widely used.

China's processor research and development started relatively early, but the development process is relatively bumpy. In the sixties of the last century, microprocessors based on ultra-large-scale integrated circuits had not yet appeared, and the computer system was a large-scale processor with large volume and slow computing speed. At that time, the computer systems used in China were all independently designed, and there was not much gap with the international level, and the landmark products included the transistor 109 machine (developed in June 1965).

Fudan UniversityFudan University is one of the earliest universities in China to study microelectronics technology, and in 1988, Fudan University's "Microelectronics and Solid-State Electronics" was selected as a national key discipline.

Microelectronics and solid-state electronics belong to the first-level discipline of electronic science and technology.

The electronic science and technology of Fudan University was later listed as a national first-class key discipline. Therefore, Fudan University's chip R&D capabilities are at the top level in the country.

2. Peking University. The electronic science and technology disciplines of Peking University are all national first-class key disciplines, according to the fourth round of discipline evaluation of national universities.

As a result, the university's electronic science and technology disciplines have all been ranked among the top five universities in the country, and the electronic science and technology discipline of Peking University was also selected as a "world-class discipline construction discipline" in 2017.

Tsinghua UniversityTsinghua Academy, the predecessor of Tsinghua University, was founded in 1911.

And the name is Qing **.

Preparatory schools for studying in the United States. At present, Tsinghua University has 20 colleges and 58 departments, and has become a comprehensive research university with disciplines such as science, engineering, literature, art, history, philosophy, economics, management, law, education and medicine.

4. University of Electronic Science and Technology of China. The University of Electronic Science and Technology of China is a famous university in the field of information technology in China, and the School of Electronic Science and Engineering of this university is one of the first batch of demonstration microelectronics colleges in China.

At present, the School of Electronic Science and Engineering of the University of Electronic Science and Technology of China has three full-time academicians of the Chinese Academy of Sciences and the Chinese Academy of Sciences.

And have integrated circuits.

and integrated system innovation and intelligence introduction base, low-power microelectronics and microsystem innovation intelligence introduction base.

Xidian UniversityXidian University is also a famous university in the field of information technology in China, although this university is not a 985 university.

However, in the field of information technology, it is comparable to Tsinghua University and Peking University. In chip research and development, Xidian University is also strong, as early as 2003, this university has become a national integrated circuit talent training base allocated special funds for the construction of China.
