Liang Yuan looked at the thin silicon crystal in his hand, and the gray-black surface of the back of the processor was printed with a constantly twisting Mebius ring, which looked very similar to the triangular loop icon that was common on computers in later generations, similar to the trash recycling bin, this thing should be the latest trademark designed by Su Liangyu and others for the chip real room.

After staring at Mebius for a few moments, Liang Yuan felt that this pattern with eternity, infinite exhibition, and even involving the fourth dimensional space was in line with the significance of microprocessors to human beings, and when the information age came, in a sense, the earth's civilization should be a history of carbon-based compounds based on silicon.

The right side of the product logo is printed with a capital art C2, and the word RISC falls on the back of C2, indicating that this is a processor with a reduced instruction set, but below it is a row of production number numbers such as NH1OO1127, and the working voltage of this CPU is marked below the number number3.2Volt.

Liang Yuan put this CPU in his hand over and over for a long time, although with a lazy smile on his face, it looked unfazed, but in fact, the love in his heart had already rolled like a huge wave, except for a small number of people, no one would realize how much impact this small silicon crystal would have on the entire human society.

In the 80s, it was the key era when the industrial system of the traditional industrial powers in the West transitioned from combined industrial automation to intelligent automation with chips as the core, and the mainstream CPU frequency broke through 1OOMHZ on a large scale as a sign of the maturity of intelligent automation, and this kind of technology was only left for five or six years. The peace winds of the information age are already blowing in our faces.

Now, Liang Yuan finally opened the door and squeezed in before the semiconductor train drove onto the high track.

"Lao Su, what is the main frequency of this CPU?" Liang Yuan finally raised his head and looked away from the chip in his hand.

Tang Wan has been famous for the high-tech of electronic computers for a long time, listening to the conversation between Liang Yuan and Su Liangyu, the small black sheet in Liang Yuan's hand is the brain of the electronic computer, not only interested, but also took the chip from Liang Yuan's hand and looked at it carefully.

"From 16MHz to 22MHz, it can be said that it is the highest frequency in the world's 8O286 level chips. It is 2MHz higher than the AM286Pro launched by AMD in 1984. Su Liangyu said with a smile.

It looks like there's only a four-year gap. It is within reach, but Liang Yuan clearly realizes that this C2 processor is the ultimate that the chip real room can do at present, and the 16-bit processor has entered the elimination stage. 32-bit is the enduring mainstream in the history of processor exhibitions in the future. This newly-born C2 processor was destined to be a short-lived fate.

"Listen to Lao Su. It seems that we have grabbed the tail of the international mainstream level, are there any shortcomings in the patent?" Liang Yuan asked with a smile.

Lao Fang's thinking is actually similar to that of Dr. John Hennessy, who founded MIPS at Stanford, but Wang An Computer was not optimistic about the C2 processor at the beginning. When the old side developed C2, the resources were limited and had to start with the 16-bit processor, while John Hennessy started from the 32-bit, and there were many similarities between the two buses and instruction sets in terms of patents. ”

"What's the difference now?" Liang Yuan asked curiously.

"The asking price of MIPS is too high, from the patent layout, involving the RISC architecture and MIPS instruction set of the basic patents as many as more than 20, although some patents of the C2 processor have the possibility of shaking the foundation of the MIPS patent, but the path to the upward development has been blocked by the MIPS, in the face of this situation, MIPS opened a price code of 100,000 US dollars for a basic patent authorization, and at the same time, all the patents of the C2 processor are owned by the MIPS company....... Su Liangyu and Liang Yuan explained in detail the complex patent relationship between C2 and MIPS.

A large list of proprietary computer words made Liang Yuan dizzy when he listened, and when Su Liangyu was still unfinished, Liang Yuan hurriedly asked: "Old Su, what are the chances of winning the lawsuit with MIPS Company?

According to the company's legal counsel in the United States, lawyer Zhang Jianxin, even if we enter the judicial process, the possibility of settling with MIPS in the future is still the greatest, but we will have a great chance of obtaining the right to use MIPS technology and part of the patent ownership for free. Su Liangyu explained.

"In fact, the MIPS company's asking price of 2 million is also related to the R3oo chip that it is currently fully open, according to my old colleagues in the United States, MIPS company's financial situation is very tight, if there is no such factor, MIPS is still very open to patent licensing. Fang Dongxing added.

"Old Su, the technology derived from the basic patent should belong to us, right?" asked Liang Yuan.

"Well, we have complete and exclusive ownership of all patents derived from the twenty basic patents. Su Liangyu nodded and said.

Liang Yuan tapped his fingers on the surface of the coffee table, his head was flying, on the one hand, the long-term lawsuit and the ownership of some MIPS patents, on the other hand, two million US dollars and the right to use MIPS patents, gritted his teeth, Liang Yuan still decided to settle down.

Although the partial ownership of MIPS patents looks beautiful, but this kind of large-scale patent lawsuit will not produce any results at all in three years and five years, and there are too many uncertain factors in the imminent great changes in the international shape, two million is two million, and the right to use is the right to use, from the architecture based on MIPS technology, the multi-threading technology of the development processor and the power consumption of high-performance embedded processors have great advantages compared to Arm, which will have a dominant position in the field of smartphones in the future.

Of course, Liang Yuan was willing to pay two million dollars. According to Liang Yuan's estimate of the future, it is not uncommon for the production of RISC chips to reach hundreds of millions of pieces in the future, and if each chip pays a certain licensing fee for MIPS, even if the lawsuit is fought for 1O years, Liang Yuan will stick to it.

After having all the authorization of MIPS, the chip room can open a variety of high-performance chips based on MIPS patents at will, without having to design chips across industries and deeply change the CPU architecture, and then re-obtain the architecture authorization from MIPS companies.

To put it bluntly, in addition to the American MIPS company, the chip real yàn room is equivalent to a Chinese MIPS company. In addition to the fact that there is no external authorization of the processor architecture for this right. The remaining rights are no different from the American MIPS, which is much more free than the deep authorization of ordinary processors.

"Fang Gong, I read the follow-up research report of the chip room some time ago, you have already put the C3 processor on the agenda, right?" Liang Yuan asked Fang Dongxing.

"Yes. The C2 is a full-fledged processor. In terms of structure, not much effort was put into the room. Just concentrate on improving the process of mass production, and the focus of the real research room is always on C3, and the entire project progress has been completed by 15%. Fang Dongxing briefly talked about the research progress of the C3 processor.

Liang Yuan estimated the time. According to the current research progress of the chip room, it will take at least 2O months to complete the C3 processor from 16-bit to 32-bit, and if you count the steps of small test, pilot test, tape-out, etc., it will take at least two years to go offline, which is really a bit unbearable for Liang Yuan, who is in urgent need of high-performance chips.

"Fang Gong, you just mentioned that MIPS is very open in terms of licensing processors, and the company's funds are tight, do you think it is possible for us to buy back the full license of the 32-bit RISC processor R2oo developed by MIPS in 85. Liang Yuan asked with a deep groan.

"Xiaoyuan is planning to integrate the C3 project with R2oo's technology?" Fang Dongxing asked.

Liang Yuan nodded and said: "Fang Gong, after the chip is successfully taped out, there are two main application directions, one is a variety of control chips based on C2, and the other is a level computer based on C2 processor. ”

"For all kinds of control chips, performance is not the most important, C2 can be fully afforded, but for the level of computers is different, in the case of using the same number of CPUs, C3 processing power can be at least 2 times more than C2. ”

"I think since the C3 processor and MIPS' R2oo are based on a technical system, the integration should greatly increase the degree of the C3 processor off the assembly line, of course, now these are my wishful thinking, whether it can be realized or not depends on the meaning of Fang Gong and Lao Su, after all, you are professional. Liang Yuan said sincerely.

"Used in the class computer, of course, the 32-bit processor has a huge advantage, Xiaoyuan's idea is good, but it is really hard to say whether it can be fully authorized by the R2oo chip, if we put this condition in the package of patent negotiations, and then pay a certain price, it is still possible to succeed, MIPS does not want its own patent system to have a heavy Dà vulnerability, and it is reasonable to use the technology of the previous generation to make appropriate compensation. Fang Dongxing said while thinking.

"Xiaoyuan has decided on the higher-level computer project?" After Fang Dongxing finished speaking, Su Liangyu asked with some surprise.

Liang Yuan nodded and said: "My mother has been talking with the British Rolls-Royce Company for more than a month, and it is estimated that the entire set of technology introduction agreements can be signed before New Year's Day. ”

"After having a certain foundation, no one can count on the follow-up research, and it is even more unrealistic to get a quick breakthrough from metallurgy and materials, so my mother put the idea on the design, anyway, I heard her say that at least 4o billion times per second are needed to run more than 4o billion times per second, in order to solve the new problems encountered in the design. ”

For the structure and focus of the entire Yuanjia, Su Liangyu is very clear, so there is no big surprise for Liang Yuan's determination to research computers, from the perspective of being based on the country, the research risk is small, the profit is high, and it is much more cost-effective than engaging in personal computers, for the Republic in the eighties, the annual computer consumption will not exceed 1o thousand units.

"4o billion times per second, which is about the same as the fastest Clay-28 computer in the United States equipped with the Roland Livermore National Real Yàn Room in California, USA, Xiaoyuan, Xiaoyuan, your requirements are really not low. Su Liangyu smacked his mouth and said.

"Lao Su, is this thing difficult, it's almost the same when you use 2oooo3oooo C2 processors to combine them. Liang Yuan asked puzzled.

"Xiaoyuan, not to mention the difficulty of parallel computing of 2oooo chips, the server cabinets used by the 2oooo processors alone can be connected together, at least four or five kilometers long, even if they are installed in a high-density way, they need a place the size of a football field to be placed. ”

"Wouldn't it, how do I think this room should fit in" Liang Yuan's face was full of disbelief, and he casually said the cognition from his previous life.

In Liang Yuan's memory, the computers of later generations all used multi-core blade servers, similar to Tianhe-level computers, which are composed of million-level chips, and they did not need a place as big as a football field.

"How is that possible. Su Liangyu and Fang Dongxing said with a smile.

"The level computer in Xiaoyuankou needs at least 2oooo CPUs, even if it is a high-density rack server, a cabinet needs to be close to 3ooo cabinets based on 7U, and the width of a cabinet is close to half a meter ....... Fang Dongxing calculated a detailed account for Liang Yuan to see how this place with the size of a football field came about.

After listening to Fang Dongxing, Liang Yuan intuitively felt that something was wrong, even if the processor in the future has more cores, a processor with 8 cores will be up to the sky, and a computer like Tianhe still has to face 1o million level processors, if it is according to Fang Dongxing's arrangement, I am afraid that a football field will not be able to put it down.

Something must have gone wrong, Liang Yuan bent his finger and tapped his forehead, thinking about Fang Dongxing's words, trying to find the root of the problem. (To be continued.) For mobile phone users, please go to read. )
