The Science Fiction World of Xueba

September 15, 1994.

Shencheng Airport.

Pang Xuelin and Liu Qi stood together at the passenger exit, watching from a distance Ni Guangnan and an old lady in her sixties came out with a dozen men and women of various ages.

The old lady was dressed in a simple and elegant way. Although she was in her sixties, with fair skin and delicate face, she could vaguely see the demeanor of her youth in her eyebrows and eyes.

Pang Xuelin took the initiative to greet him: "President Ni, welcome to Shencheng, who is this?"

Pang Xuelin turned his gaze to the old lady beside Ni Guangnan.

Ni Guangnan smiled and said, "Mr. Pang, let me introduce you. This is Academician Xia Peisu of the Chinese Academy of Sciences. I heard that you are planning to engage in HiSilicon semiconductors. She came here to take a look."

"Academician Xia, hello!"

Pang Xuelin and Xia Peisu shook hands and smiled.

In fact, Pang Xuelin vaguely guessed the other party's identity long before Ni Guangnan introduced him.

Xia Peisu, academician of the Chinese Academy of Sciences, the founder of China's computer industry, is known as the mother of China's electronic computers, and is an extremely rare female computer expert in this era.

In 1958, she was responsible for the design and development of General Electronic Digital Computer 107, which was the first self-developed general electronic digital computer in China. Facts and actions proved that Chinese people at that time had the ability and ambition to design and develop their own computers.

She proposed the principle of the maximum time difference pipeline, which greatly improves the computing speed of the computer, which greatly shortens the clock cycle of the pipeline computer.

In addition, she also effectively solved the problem of waveform distortion during high-speed signal transmission in large computers.

This research result has been adopted or referenced by many domestic units developing large-scale high-speed computers. Based on this, she also formulated specific engineering design specifications for the multiple high-performance computers she was responsible for designing and developing later, and achieved good signal transmission effects.

She is responsible for the successful development of the high-speed array processor 150-AP. The calculation speed of the 150 computer is 1 million times per second, and the calculation speed of the 150-AP has reached 14 million times per second. The calculation speed of similar products embargoed by China has received great attention internationally and has made a significant contribution to China's oil exploration.

She presided over the functional distributed computer system, led the team to successfully develop the GF10 series computer,

This direction later became the research focus of the Institute of Computing Technology for a period of time.

In addition, she also founded the "Journal of Computer Science", which is the most influential in China's computer field, and "Journal of Computer Science", which is published abroad; she presided over the compilation of "English-Chinese Computer Dictionary", etc.

In later generations, academician Xia Peisu is known as the mother of Chinese computers and has a lofty status in the computer field.

"President Pang, hello!"

Xia Peisu looked at Pang Xuelin with some scrutiny.

She had heard a lot of rumors about this young man, what a genius boy, the youngest richest man, and a young entrepreneur.

But what attracted Xia Peisu the most was the paper written by Pang Xuelin on the outline of computer and Internet development.

That paper's elaboration of the entire ICT industry from a strategic position gives people a dreamy feeling of breaking through time and space and seeing through the fog of the future.

Because of this, Xia Peisu became very interested in Pang Xuelin.

It's a pity that she didn't know that Pang Xuelin had gone to the United States until she wanted to talk to Pang Xuelin.

This delay, nearly half a year has passed.

This time, she accidentally learned from Ni Guangnan that Pang Xuelin would set up HiSilicon Semiconductor in Shencheng, and invited Ni Guangnan and his team to settle in. She came along on a whim.

Pang Xuelin and Xia Peisu exchanged pleasantries, and then, Ni Guangnan first introduced to Pang Xuelin the team members he brought out from Lenovo.

These people are talents in the field of microelectronics that Ni Guangnan managed to poach from the Chinese Academy of Sciences and various universities. Most of them are not well-known, but Pang Xuelin did not expect to find a few future masters from these people.

After all, this era can be regarded as the dark age of China's semiconductor industry. If China does not intervene, China will have to explore for many years at least. After experiencing many setbacks, it will gradually get on the right track after 2010.

It was the two students brought by Xia Peisu that attracted Pang Xuelin's attention.

One of them is Hu Weiwu, the father of the later Godson.

This is a great man.

Hu Weiwu was born in a teacher's family in Yongkang, Zhejiang. When he was born, his body was relatively weak. His father named him "Weiwu" and hoped that his son would be strong, tall and heroic.

In September 1986, Hu Weiwu entered the University of Science and Technology of China as the champion of the college entrance examination in Yongkang County, Zhejiang Province.

The University of Science and Technology in that era was still more powerful than Qingbei.

Of the 600 to 700 students enrolled by the University of Science and Technology, 13 are provincial-level college entrance examination champions.

This shows Hu Weiwu's strength in high school.

After entering university, Hu Weiwu showed an amazing talent. During his university days, he used 74xx chips to solder an 8086 CPU.

In July 1991, after graduating from the University of Science and Technology of China, Hu Weiwu entered the Institute of Computer Technology, Chinese Academy of Sciences to study for a Ph.D.

During his PhD, his advisor was Academician Xia Peisu.

From undergraduate to master's and doctoral degrees, Hu Weiwu has been in China, and he can be called a true "native school", and he even dubbed himself the "local turtle school".

There are many opportunities for him to study abroad. His doctoral dissertation has won the "Special Award of the President of the Chinese Academy of Sciences Scholarship" and the first "National Hundred Outstanding Doctoral Dissertations" award. One of the awards is to go abroad at public expense.

But Hu Weiwu still decided to stay in the country, willing to be a "Turtle Sect".

There is no doubt about the level of Hu Weiwu. The two textbooks written by him, "Basics of Computer Architecture" and "Computer Architecture", can be called classics. They explain the computer system in a very thorough manner with the same method as a dog solving a cow. .

When Pang Xuelin studied computer-related materials in the real world, he read textbooks written by Hu Weiwu.

It's a pity that fate dictates it.

In early 2000, when the Institute of Computer Science of the Chinese Academy of Sciences decided to develop a general-purpose processor, Hu Weiwu chose the MIPS architecture instead of the later ARM architecture.

But this is also hindsight.

In fact, ARM did not develop very well before 2000. At that time, the strongest core design that ARM could come up with was only a very primitive ARM11, without out-of-order execution, without multi-launch, and without a cache system.

The original goal of Godson was desktop and supercomputing systems, which required high computing performance and could compete with the X86 system.

In contrast, the MIPS architecture realized advanced designs such as out-of-order four-launch, deep pipeline, branch prediction, register renaming, and Load-Store speculation in the 1990s. It is a CPU architecture that can compete with the X86 system worldwide. One, once brilliant.

In the 1990s, home game consoles that were popular all over the world generally used MIPS architecture CPUs, such as the well-known R3000A of SONY, the later R4000 of PSP, and the R4300i of Nintendo N64, as well as the CPUs of Motorola, Ericsson, Nokia, Cisco, Qualcomm, and SUN. , and other communications giants use MIPS chips in switches, routers, and communications equipment.

In the case that the patent barriers that the x86 camp has been operating for many years cannot be broken, the choices that can start for Chinese CPUs at that time are nothing more than MIPS, ALHPA, and ARM.

ARM is still in its infancy, and the MIPS architecture is used by a large number of Japanese technology companies as the main CPU of user terminal equipment due to its excellent computing performance. This has important reference value, so Hu Weiwu, the father of Loongson, chose MIPS.

It's just that no one thought that the MIPS architecture, which was still hot before, would fall apart in the end, and Godson became the only user of this architecture.

Loongson started to operate independently very early, and was responsible for its own profits and losses.

During the nearly 20 years of Godson's career after its birth, Hu Weiwu's team relied on meager income and the hard support of the Chinese Academy of Sciences to provide support for the development of our country in the fields of supercomputing, military, and aerospace as much as possible.

And formed a set of independent chip system.

The total R\u0026D expenses for the past two decades are less than two billion, which is equivalent to a fraction of Intel's annual R\u0026D expenses.

Without the full support of the state and the support of related industries, Hu Weiwu can be said to have achieved the ultimate in what he can do.

In his 20 years of teaching and scientific research career, Hu Weiwu also brought out many top talents in the field of microelectronics.

Among them, the most famous is Chen Yunji, who later founded the artificial intelligence chip Cambrian.

This boss led the Intelligent Processor Research Center of the Chinese Academy of Sciences in later generations and developed the world's first deep learning dedicated processor chip, which is regarded as the pioneer and pioneer in the field of artificial intelligence chips.

"President Pang, what's the matter?"

Seeing that Pang Xuelin was always staring at his disciple, Xia Peisu couldn't help feeling a little strange.

Pang Xuelin shook his head and said with a smile, "It's nothing."

Calculated according to the time, this year should be Hu Weiwu's last school year studying with Xia Peisu. Pang Xuelin would feel sorry for such a boss with a solid foundation and unlimited potential if he didn't fool him into working under him.

Next, Pang Xuelin and Liu Qi took Xia Peisu and Ni Guangnan onto a bus, and first led everyone to settle in a five-star hotel in Shencheng.

After lunch, Pang Xuelin took Ni Guangnan and Xia Peisu to the Shenyi Industrial Building in Nanshan District.

It is also the headquarters of Huawei.

Pang Xuelin has already used his ability to spend 500 million RMB to completely buy this building, and prepares to use it as the headquarters of Huawei and HiSilicon Semiconductor in the next few years.

Warwick also saves the need to keep moving around as the scale expands.

After arriving at Shenyi Industrial Building, Ren Zhengfei and the others had been waiting for a long time.

Pang Xuelin first asked Ren Zhengfei to take the people brought by Ni Guangnan to visit, and he himself took Xia Peisu and Ni Guangnan around the building first to let them get acquainted with the next office environment. They came to the meeting room of Warwick Company.

At this time, Ni Guangnan knew that Pang Xuelin actually owned 49% of Warwick's shares, and he couldn't help but sigh with emotion: "Mr. Pang, Huawei's current program-controlled switches are selling very well in the market. You are almost eating away at me, but I didn’t expect Warwick to be your company. Coupled with the ever-growing Xinghuan Technology, I think you have deserved the title of China’s richest man.”

Pang Xuelin smiled and said: "Ni Gong, these are just false names. To be honest, making money is meaningless to me. What I value more is whether the money can be converted into the scientific research resources we need."

Ni Guangnan nodded and said, "Mr. Pang, then I won't talk nonsense with you. If HiSilicon Semiconductor wants to develop chips next, have you considered the architecture? There are not many in the market that can compete with the X86 architecture. "

Pang Xuelin shook his head with a smile, and said: "Ni Gong, I originally wanted to acquire the ARM architecture and do it myself, but it failed. The British refused to sell us the ARM. So after thinking about it, I think that if we really If we want to make a chip that really belongs to us, then we must design a set of our own architecture system."

"Our own architecture?"

Ni Guangnan and Xia Peisu looked at each other and said in surprise, "Mr. Pang, this difficulty is not as simple as you think."

To develop a new architecture, the most difficult thing is not the technical level, but the time, money, and ecosystem.

On the one hand, the R\u0026D structure actually requires time accumulation and a lot of financial support.

Without these two, there is basically no way to talk about the development of new architectures.

But at the same time, the ecosystem is also a top priority.

The desktop processor market of x86, the low power consumption market of arm, and the cheap market of mips.

Even if you develop a new type of instruction set, but others don’t use it, you won’t get money if you don’t use it, and you can’t continue to develop if you don’t get money. This is an endless loop.

Therefore, in a sense, the importance of the ecological circle is far greater than that of technology. Once an advantage is established, it is difficult to overthrow it, just like the force of MAC is high, and it is impossible to overturn windows.

No matter how smooth wp is, it is like cannon fodder in front of Android.

With the new instruction set developed, how many applications are willing to optimize for you? How many people can agree and use it?

It's all a problem.

And the instruction set needs the support of the system. Is it useful for you to pirate other people's Windows system and Linux system, saying that you developed it yourself?

After all, it is impossible to develop your own instruction set on other people's systems. If you want to develop your own good instruction set, you must first develop a good system and a good CPU.
