Free Science Chapter

  Li Guojie, from Shaoyang, Hunan.

   In 1985, he studied for a doctorate at Purdue University in the United States. After graduation, he joined the CSL laboratory and returned to China after many years.

In the field of integrated circuits and semiconductor physics, Li Guojie is only a junior. When it comes to his contributions to the country, he may not be ranked in the top ten. The reason why he is introduced in the popular science chapter is because Li Guojie has been in the 21st century. It is a scientific research worker who is struggling on the front line.

Anyone who is a little old will remember that in the 1990s, the American government strictly restricted the export of supercomputers to flower growers. In addition to the high purchase price, the computer was also placed in a transparent glass room, and the key was in the hands of the American people. , and each time you use it, explain the specific purpose to them.

   This is the famous glass house shame.

  In 1990, the state established the Intelligent Computer Research Center, Li Guojie was appointed in danger and served as the director of the center.

   He once said: "I thought about coming back before I went abroad. It's like asking someone why they choose to go home. There is no reason, just go home!"

  At the same time as the computer research center, Li Guojie also has a position, the CEO of "Dawning" company!

  In 1993, Dawning-1 was successfully developed, and the computing speed per second reached the world's advanced level at that time. On the third day of its birth, the United States announced the lifting of the embargo on computers with less than 1 billion times.

   The shame of the glass house was found by the flower gardener himself.

  In 1999, Academician Li Guojie served as the director of the Institute of Computer Science.

  On the condition of almost no funds, the Loongson research group was established, Loongson, a real general-purpose CPU.

   Hu Weiwu, who has worked in the Computer Institute for six years, was appointed as the head of the Loongson research group.

  In the early days, there was not a penny. Preliminary results must also be produced.

  5 months later, the results came out. Li Guojie took out all the 10 million innovation funds of the Institute of Computer Science and invested all of them into the Loongson project team.

After   , Hu Weiwu and 100 researchers in the system resigned from relevant public positions and established Godson Zhongke Technology Co., Ltd.

   In 2002, Godson-1 came out.

  Not long after the news could not be sent out, Hu Weiwu received a letter: "I am a retired worker, and the salary is not high, but please give me your bank account, and I will donate 1,000 yuan to you!"

   Today, as far as I know, Godson is explicitly applied to our Beidou system.

   In addition, although Loongson's IP core and instruction set were originally foreign, they should have obtained the final permanent authorization (to be verified).

  In addition to Godson, there is another heart, which is also introduced here.

  The combination of these cores produces a supercomputer with a peak performance of 12.54 memory times per second, and a maximum floating-point operation speed of 9.3 memory times per second in stable operation.

   This core is called Shenwei 26010 many-core processor chip, 64-bit autonomous (ALPHA architecture), 28nm node process, clocked at 1.45G and has 260 cores.

  The supercomputer composed of it, coupled with the autonomous Shenweiris operating system, won the championship at the 2016 International Supercomputing Conference.

   That was the world's No. 1 "Shenwei - Light of Taihu Lake" at that time

   At the time of writing this book, Xiaojia was getting divorced and everyone was being sanctioned by ZTE.

   Therefore, at the beginning of this book, the three views of the small family are not very correct, and the three views of everyone... should be very positive.

  Flowers are events, not in the outline, and don’t do much evaluation until the event is over.

   Here, I just want to apologize to my book friends for the description of ZTE Group in the public chapter.

   In the 2017 international PCT patent applications, ZTE Group is the world's first.

  2018 is the second year, and the first is Huawei.

   The one that gets stuck is related to analog circuits. At present, in the high-end field, my country's self-sufficiency rate is 0. ZTE can't do it. If you switch to other companies, it won't work either. It's just that ZTE has taken on the infamy.

If the LCD screen is also included in the integrated circuit industry, so far, the company that has contributed the most to the flower growers is not Huawei, not ZTE, but BOE, which has been paying for ten years in a row (personal opinion, don’t spray, the text will not have this view.)

  Because of BOE, we can watch cheap LCD TVs and use cheap LCD mobile phones!

   Follow-up, will meet the stabbing incident on the LCD screen of Science Bay Bay.

  Some book friends said that I should add something or something. Actually, I really don’t have much of such thoughts. If there is too much discrepancy between the paragraphs that imply reality and reality, and there is suspicion of Timing, please let me know and I will delete them!

In fact, sometimes I also complain that there are more than 9 million square kilometers of land and a population of more than one billion. What kind of economy did you develop in the first place, and how good it is to invest all your money in the integrated circuit industry. A full-fledged keyboard sprayer, what's the picture?

  Who knows what the picture is. There are a lot of complaints in the book, and it's just the complaints of a small commoner.

   In general, the people I love are all in this country, and what I write is the language of this nation, and my parents today are all people who read this language!

   So, I love this country!

  No problem!

   There are many documentary memoirs for reference, and try not to read what Qianduqianke can not read.

  References:

  《CHIPS》

   "The Game and Breakthrough of China's Chip Industry"

  《Core Matters》

   Xu Kuangdi "My Academic Career"

Wait.

   Finally, let me explain that, in reality, flower growers have replaced the United States as the world's largest integrated circuit market, and a full-scale war will be lost.

   Regarding Huawei, please refer to the Toshiba incident, there are many more on the Internet. The means are the same.
