Rebirth Turn of the Century

Li Guojie, from Shaoyang, Hunan.

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

Li Guojie is just a junior in the field of integrated circuits and semiconductor physics of flower growers. Speaking of his contribution to the country, he may not be ranked in the top ten. The reason why he is introduced in the single chapter of popular science is because since entering the 21st century, Li Guojie has been It is a scientific research worker who is struggling on the front line.

Any book lover 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 had to be placed in a transparent glass room, and the keys were in the hands of the Americans. , Every time you use it, explain the specific purpose to them.

This is the shame of the famous glass room.

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

He once said a word: "Before I went abroad, I wanted to come back. It's like you ask a person why he chooses to go home. There is no reason, just go home!"

At the same time as the computer research center, Li Guojie also has another position, the boss of "Dawn" company!

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

The shame of the glass house was brought back by the flower grower himself.

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

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

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

In the early days, there was no penny. Preliminary results must also be produced.

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

After that, Hu Weiwu and one hundred researchers in the system resigned from relevant public positions and established Godson 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 my salary is not high, but please give me your bank account number, and I will donate 1,000 yuan to you!"

Today, as far as I know, Godson is clearly used in our Beidou system.

In addition, although the IP core and instruction set of Loongson were originally imported from abroad, they should have obtained the final permanent authorization (to be verified).

In addition to Godson, there is another heart, and I will also introduce it here.

These cores are combined to make a supercomputer with a peak performance of 12.54 times per second, and a maximum floating-point operation speed of 9.3 times per second for stable operation.

This core is called Shenwei 26010 multi-core processor chip, 64-bit independent (ALPHA architecture), 28nm node technology, main frequency 1.45G with 260 cores.

The supercomputer composed of it, coupled with the autonomous god Veris operating system, won the championship in one fell swoop at the 2016 International Supercomputing Conference.

That was the world's number one "Shenwei—Light of Taihu Lake"

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 correct, but the three views of everyone... should be very correct.

The flower is an event, not in the outline, and there is no more evaluation before the matter is over.

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

In the 2017 international PCT patent application, ZTE Group is the first in the world.

2018 is the second, and the first is Huawei.

What is 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, and it can't be replaced by other companies, but ZTE has taken the blame.

If LCD screens are also counted in the integrated circuit industry, so far, the company that has contributed the most to flower growers is not Huawei, not ZTE, but BOE, which has been losing money for ten years (personal opinion, don’t spray, it won’t be mentioned in the text) There is this point of view.)

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

In the follow-up, there will be a stabbing incident on the LCD screen in Kepu Bay.

Some book friends said that I added something, and so on, but in fact, I really didn't have much thought about it. If the paragraphs in the article that allude to reality are too different from the reality, and there is suspicion of adding, please tell me, and I will delete it!

In fact, I sometimes complain, more than 9 million square kilometers of land, more than one billion people, what kind of economy did you develop at the beginning, how good it was to invest all the money in the integrated circuit industry, you see, now that the economy is booming, you have raised a group of food Full of keyboard trolls, what are you trying to figure out?

Who knows what to draw. There are a lot of complaints in the book, but they are just the complaints of ordinary people.

Generally speaking, all the people I love are in this country, what I write is in the language of this nation, and my current parents are all people who read this language!

So, I love this country!

Nothing wrong!

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

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 cause both sides to suffer.

Regarding flowers, please refer to the Toshiba incident, there are too many on the Internet. The means are exactly the same.
