The call was from Li Wenjing,

"Wang Yinan! Get back to me, it's been more than a month, and your vacation should be over", Li Wenjing is still the eldest sister's tone,

"What's the matter, my side is almost over", thinking of losing the company to Li Wenjing for so long, Wang Yinan is still a little guilty.

"Sun Wei came up with a super idea, which can improve the performance of the Gödel system by more than an order of magnitude"

"I'm damned, so bullish B, what do you think, hurry up and tell me, I'll see if it's reliable",

"Cut, it must be reliable, do you want to know, no way, think about it yourself slowly, and I can tell you when I come back."

Wang Yinan almost didn't choke to death in one breath, how did this such a simple girl become like this. He doesn't want to think about the so-called red who is close to Zhu and black who is close to ink, and who Li Wenjing is mixed with after graduation.

After Wang Yinan answered the phone, he ran back to ask Leng Feng for leave, Leng Feng thought that this guy is now practicing drag racing, and the firearms have been almost practiced, and then he should teach the girl to fly a plane, forget it, anyway, I don't expect this demon to help him start a fight or something in the future, Leng Feng drove Wang Yinan back directly.

"You've graduated, let's go, if you don't leave, so many students on my side should doubt life."

Wang Yinan was thrown outside the barracks in a gray manner, and called Qian Zhonghua, but no one answered the phone for a long time, Wang Yinan hesitated for a long time, and was still embarrassed to call Deng Ruoyan to pick him up, probably because he was afraid of going to Ronghe Company, and accidentally got into a fight.

There was no way, Wang Yinan had to carry a huge shoulder bag and start the last training content, a ten-kilometer cross-country run.

Panting and running to the company's yard, Wang Yinan felt that this training camp was quite effective, such a long distance, how could it take an hour before, but this time he ran back in less than forty minutes.

When I walked into the office, I found that a group of people were discussing around Li Wenjing, Wang Yinan was immediately unhappy, what do you mean, the boss is not in a few days, and he is going to turn the rhythm of the sky?

Wang Yinan leaned over, Li Wenjing had already seen him coming, so he deliberately pretended not to see it, it is estimated that his anger has not subsided, she continued,

"Sun Wei's plan is very good, let's see if there is anything to add, if there is no supplement, just implement it according to this plan", several unscrupulous subordinates agreed, "Uh-huh, indeed", "I'm responsible for this part", "The part I'm responsible for is fine", "Mine is no problem",

Li Wenjing asked around, and finally said, "Then let's disperse", after speaking, everyone dispersed in a hurry, leaving Wang Yinan standing on the edge of the whiteboard stupidly.

"I'll go", Wang Yinan knocked on the whiteboard, "Hey, hey, hey, you don't exist for me", but everyone was busy in their positions, but no one paid attention to him.

After a long time, Li Wenjing paced over slowly, she looked Wang Yinan up and down carefully, "Hey, it feels a little different",

"Of course, I'm a man with eight-pack abs now", Wang Yinan said very proudly,

"It's really fake, come, let my sister touch it", Li Wenjing came up and was about to lift Wang Yinan's clothes, so scared that Wang Yinan shouted while hiding, "Hey, hey, don't be a hooligan."

Although Zhang Zifeng is far away, her ears are pointed, as soon as she heard Wang Yinan say about eight-pack abs, she was immediately happy, "Come on, boss, I haven't had a boyfriend with eight-pack abs yet."

"Why don't you let me touch it, and let's look around?"

These two female hooligans, Wang Yinan was so frightened that he was about to flee in the wilderness, Li Wenjing grabbed him and handed him a document, "Oh, this is Sun Wei's plan, you take a look first",

Wang Yinan grabbed the file and ran away, when he encountered some problems that needed to be considered, he didn't like to stay in the office, the small river, the bridge and the flowing water outside, it was a rare scenery in the imperial capital, although the weather had gradually cooled, but it was still very warm in the afternoon, while strolling on the tree-lined path by the river, while watching Sun Wei's whimsy, it was also a rare enjoyment.

This document is just a thin two-page paper, and as soon as he saw the title, Wang Yinan was startled, "From FPGA to CPU & GPU",

This is going against the sky, Wang Yinan thought, he actually started the idea of CPU, but it seems to make sense, when discussing the Gödel system performance improvement plan before, he once said that the performance improvement of FPGA has basically come to an end.

However, if you don't care about the cost and frantically pursue performance, the CPU or GPU, a specialized integrated circuit, must be far better than the FPGA, because after all, the FPGA emphasizes programmability, that is, similar to the interpreted programming language, and the CPU or GPU emphasizes the performance, that is, the similar compiled programming language.

Generally, the CPU/GPU in the same period, first of all, is much larger than the FPGA in terms of scale, a typical GPU can contain more than 10 billion transistors, and the number of FPGA transistors is a few percent of the GPU, and secondly, in terms of manufacturing process, the general GPU is at least one generation ahead of the FPGA generation, that is, when the GPU uses the 10nm process, the FPGA may still use the 30nm process.

In the past, when using multiple FPGAs, the interconnection between chips was a big problem, and even between the chips, the cost of using optical fiber for communication was quite large, because when the process reached the nanoscale, electromagnetic mutual interference would be very serious, so the speed of communication had a certain upper limit. Sun Wei: As a result of their calculations, even if more FPGA chips are added, there is no way to improve performance.

However, if the functional module is directly made in the chip, the communication in the chip is directly completed through the silicon engraved circuit, and because of the close distance (of course, it is close, all in a chip), so the interference is small, and the communication rate can be very high.

The more Wang Yinan thinks about it, the more it makes sense, the Gödel system is such a good thing, and it is obviously too low to only use FPGA to improve performance, and there must be a special chip to reflect his extraordinary.

As Wang Yinan thought, Sun Weiyang discussed the great contribution of the direct use of special chips to the improvement of performance, and finally made an estimate that using the most advanced SMIC technology in China, it is possible to achieve 500 million transistors and 0.5 micron processes, so that the performance of the Gödel system is improved by at least five times.

It's too weak, it's too weak, Wang Yinan thought to himself, spending so much effort, can only improve the performance by five times?

The key to the problem is still in the manufacturing capacity of the chip, the current strongest chip technology in foreign countries, about 10 billion transistors and 7 nanometer process, 7 nanometer process what does it mean, modern chip manufacturing is based on the lithography machine as the core, that is, on the silicon based chip (silicon is the main component of the sand that children usually play with), use the lithography machine to carve out transistors and lines, 7 nanometer process, which means that the thinnest line carved out, the width is 7 nanometers, that is 0.0000000007 meters.

Wang Yinan calculated that if the world's most advanced chip manufacturing technology was used, the performance of the Gödel system would be improved by at least 100 times.

Thinking about it, Wang Yinan walked into the office unconsciously, and his saliva flowed down unconsciously.

"Wipe it quickly, it's ugly to death", Li Wenjing handed over a tissue,

"I dreamed of the girl of the Deng family again, it's a shame to see your drooling."

"If you want to improve the performance of the Gödel system by a hundred times, will you also drool," Wang Yinan said.

Li Wenjing's saliva also came down, "It's really fake, if anyone can improve the performance of the Gödel system by a hundred times, let Zhang Zifeng marry him."

Zhang Zifeng quit, "If you want to marry yourself, why do you let the old lady betray her hue, believe it or not, I will find a reporter to send a message tomorrow."

"Unscrupulous bosses are embarrassed, and employees are forced to betray their hues."

Wang Yinan, this waterfall sweat, there is nothing to do with the eight characters, where is this, women are really troublesome.

But the ideal is very plump, and the reality is very skinny. Wang Yinan, what they can count on, that is, SMIC's 500 million transistors and 50nm process, even if SMIC's backward process, because Wang Yinan's amount is too small, even if SMIC takes the job, it is a sky-high price.

As for better craftsmanship, please, you should be a decoration in Batumi (Batumi's full name is the Paris Coordinating Committee, established during the Cold War, mainly for woolly bears and rabbits, all developed countries according to the list listed by this committee, embargo on woolly bears and rabbits, although with the disintegration of hairy bears, Batumi was dissolved in 1994, but the rice country took the lead, a new Wassenaar agreement, Da Mao shamelessly joined this agreement, this time they only have one main goal left, you know, that is rabbits)

The most advanced lithography machine is on this embargoed list, there is no doubt that it can rank in the top three, the ASML company of the windmill country is the only leader in the lithography machine industry, ASML's EUV lithography machine, that is just like the dragon slayer knife in Jin Daxia's novel, the artifact of the artifact, before there was also the Nikeng of the Sun Country can also pretend to be the Heavenly Sword, but after the process is developed to 50 nanometers, the Nikeng will be left behind, and only the lonely ASML will be proud of the world.

EUV not to mention Wang Yinan, the whole country of China is thinking about it, tossing and turning, if Wang Yinan can get it, it is estimated that Qian Zhonghua can hold his thigh and sing conquest to him. Of course, even if the dragon team is dispatched to grab it, it is estimated that they will not be able to grab it, and the Navy SEALs of the United States are waiting, Wang Yinan does not feel that he is a superman.

The only good news is that due to the existence of the Gödel system, Wang Yinan can fully simulate and test the circuits of the chip, that is to say, the possibility of a finished product in a tape-out is still very large, at least above 90%.

Before Wang Yinan came back, Sun Wei and the others had already started the design of integrated circuits, and according to conservative estimates, plus the time of three Gödel iterations, the design of the circuit could be completed in two months.

Can you only go to SMIC? Endure its starting price, as well as the 0.5 micron performance of the pit daddy, and improve the performance of the Gödel system by five times?

With a hundred-fold performance increase, it can be seen that he can't eat, Wang Yinan is unwilling.

If only I were really Superman, even if it wasn't, Brother Tom would be fine, that Mission Impossible, it seems that what he stole was the lithography machine?
