Rebirth of the Cyber ​​Hegemony

Li Biqing nodded: "How do I feel that you want to compete with the international mobile phone giant?"

"Dreams are always there, what if they come true."

Whether Chen Yu has not yet arrived.

"I really dare to think about it."

Li Biqing gave Chen Yu a thumbs up.

But after a while, he said very seriously: "However, Chen Yu, it is really too difficult to talk about making chips."

"Dean Li, I don't understand technology, can you tell me more about it?"

"how to say……"

Li Biqing hesitated for a while.

He has some don't know how to say.

To be honest, when it comes to chips, he doesn't know where to start.

Of course, this is somewhat exaggerated.

But on the other hand, it can be seen that the difficulty of chip technology is almost no less than that of aerospace.

Even, to some extent, it is more difficult than aerospace.

After all, the country in the field of aerospace has been researching since the founding of the country, but the chip has only been paid attention to in the last ten years.Whether it is technology or theory, there are decades of gaps with foreign countries.

Otherwise, why can't even a Chinese chip be made in China now.

Speaking of it, this is really an extremely embarrassing thing.

Even if Chen Yu said jokingly just now, it's not because Shencheng University can't do it.

I'm ashamed to say that I really can't figure it out.

"Chen Yu, let me tell you about the manufacturing process of the chip first."

If you want to talk about how to make domestic chips, you really have to start with the chip technology.

"If you want to build your own chip, the first step is the chip architecture, which is chip design."

"It's understandable, it's like making a mobile phone design first."

"What do you understand, understand, do you think chip design is that simple? If it were so simple, we would have figured it out a long time ago."

Li Biqing shook his head: "Okay, don't talk about other things, just talk about the chip architecture. If you want to make a chip, the first step is to make the design. If the architecture can't be done, then there is no need to talk about production. chip."

"The chip architecture is also called the instruction set, which is the command that instructs the computer to process various operations and functions. At present, there are four mainstream chip architectures in the world. The first is the x86 architecture, which is mainly for the PC. Intel technology Most mature."

"The second is the mips architecture developed by Stanford University in the United States. This architecture is the same as that of arm companies. They mainly do not produce chips themselves. If chip manufacturers want to produce, they can purchase the license of mpis."

"The third is IBM, Apple, and the powerPC architecture developed by Motorola. This architecture is aimed at the server market, and it is not available to you for the time being."

"The fourth is the arm architecture, which is also the most widely used architecture for various electronic products and mobile phones."

Li Biqing briefly introduced the four most commonly used chip architectures to Chen Yu.

Although Chen Yu doesn't understand technology, he still understands this simple introduction.

"In other words, we can't even do the first step now?"

Chen Yu asked.

"You can't say that either."

Li Biqing shook his head, but nodded again: "It's not impossible to make it, but there are still difficulties in making a mature structure."

Having said that, Chen Yu understood.

Even if combined with the most top domestic professional research for many years, I am afraid that only a simple chip architecture can be made.And this chip architecture may be decades behind others.

If that's the case, it's not very interesting.

"At present, in the production of chips in China, we tend to purchase mature architecture solutions, and then make appropriate modifications to produce our chips. But even so, it is still difficult for us to produce more mature chips. On the one hand, our The technology is limited, and on the other hand, these chip architecture companies will not license the top chip architecture to us. What we can buy is only the low-end chip architecture.”

Chen Yu felt even more deeply about this part.

In the previous life, when the arm company was booming, it sold dozens of architecture licenses a year.

But each of them has a different structure.

In other words, Apple's chip design is different from Qualcomm's and Huawei's.

Undoubtedly, the designs of Apple and Qualcomm are even better, and Huawei's is not bad, but it is still a bit worse.

The worst is MediaTek, which is the low-end chip design.

"Buying is not an option either."

Chen Yu shook his head: "Purchasing chip architecture authorization seems to solve the temporary problem, but if you can buy it now, what if they don't sell it in the future?"

"So, there's a problem with that, too."

Li Biqing also agrees with Chen Yu's statement: "It may take a long time to do it yourself, and even if you do it yourself, you may not be able to come up with a mature design. Buying someone else's will get stuck from time to time."

"Now you know why making chips is so difficult."

Li Biqing said helplessly.

In fact, this is just chip design.

There are still many problems in chip making.

Chapter 454: Got an idea

"In fact, it's not just a question of architecture."

After Li Biqing said, Professor Wang added: "Although the design of such things as architecture is relatively difficult, as long as you find top experts to study, you will be able to research it sooner or later. The most important thing is the constraints of the entire environment."

"Professor Wang, are you talking about the ecosystem?"

"ecosystem?"

Professor Wang heard this word for the first time, but he understood it just after thinking about it: "Your ecosystem is right, it is indeed a problem of the ecosystem. Microtel's cpu is supported by Microsoft, and it runs on the Microsoft Windows operating system. Under this, a powerful ecosystem has been created. This ecosystem is so strong that Apple didn’t use Intel’s cpu in the first place, and eventually had to use it. In addition, the ARM chip is also licensed to all electronic devices because of its openness. Enterprises, so ARM can be considered to have built a very strong ecosystem."

"If we want to make our own chip, even if we make it, it will be useless without software and hardware support."

At this point, Chen Yu also nodded extremely.

In the previous life, Huawei was so powerful, why didn't it produce an independent chip, why didn't it launch its own operating system for the time being.

It's not that they don't have this technology, it's all because they haven't created their own ecosystem yet.

If they come up with their own ecosystem, whether it's ARM or Android, they can completely ditch it.

However, thinking of this made Chen Yu even more headache.

In the previous life, even Huawei didn't do it, how could I break this situation?

"The best thing to do now is to buy their license and develop your own chips."

Seeing that Chen Yu was silent, Li Biqing suggested: "Although the licenses we purchased are not the most advanced, they are still commercially available. And we can also do our own research on this basis. Let's see if the technology grows in the future." Are there any other opportunities?"

However, Chen Yu also shook his head at Li Biqing's suggestion.

Of course you can buy, but the more you buy, the deeper you sink.

Just like ARM, he uses this kind of open authorization to let the whole world cooperate with him.

After he dominates the world in the future, even if you don't want to cooperate with him, you won't be able to.

Because at this time, all the commercial markets are his, and it is difficult to replace them.

This is why ARM can be so awesome.

Speaking of which, there are more opportunities to enter the chip field at this time.

Aside from other things, at this time ARM has not yet unified the rivers and lakes.

"Is there no other way?"

Chen Yu frowned incomparably.

However, suddenly, Chen Yu thought of a new idea of ​​structure in his previous life.

RISC-V.

This is a new structure that was created in 2014 in the previous life.

However, unlike other architectures, RISC-V is open source.

Thinking of this, Chen Yu asked: "Professors, if we come up with an open source chip architecture, is there a chance?"

"Open source architecture?"

Chen Yu's proposal caught the eyes of several professors.

"The idea is fresh."

"From the operating system point of view, linux is an open source operating system."

It’s just that, after thinking about it, several professors still shook their heads: “It seems feasible, but it’s very difficult to operate in practice. In addition, there are open source software, but I’ve never heard of open source chip architecture.”

"Open source chip architecture is indeed a good idea, but if it is open source, it must have a strong company to promote it around the world. Just like windows, if there is no such company, it is considered an open source chip architecture, and cannot create its own ecosystem, which is why linux has not become popular."

"And this open source may not have many people willing to participate."

However, when Chen Yu thought about open source, he had more ideas.

"Companies like Microsoft have not appeared in China for the time being, but they may not appear in the future. As for no one participating, this is easy to solve. I can set up a foundation. As long as someone can propose a new structure and new ideas, even if they If only a little bit of the entire architecture design is completed, the foundation can reward him with a sum of money.”

"This idea seems possible, but it's impossible for you to spend money all the time."

Li Biqing asked.

"In the early stage, I can spend money first, but we can't always spend money. We can set a rule, the foundation can be divided into various parts, each manufacturer pays a sum of money, and the chip architecture designed in the future after the sum of money is paid You can use it for free without any conditions.”

"Then how do you get other manufacturers to pay the money?"

"Then see if they have this vision."

Of course, Chen Yu said so, but Chen Yu still has some confidence in this point.

Although a large number of domestic electronics manufacturers have not become bigger, it does not mean that they have no vision.

On the contrary, many large companies and enterprises have been silently waiting for this opportunity.

Of course, the interests involved in this have to be clearly planned.

Even if you want people to participate, you have to let them see the benefits in it.

Otherwise, to generate electricity for love, just to build a Chinese chip, there is no real benefit, this will not work.

After all, they are pure businessmen like Chen Yu, and they are not here to complete national tasks.Even if it is to complete the national mission, if there is no interest in it, it will be difficult to develop the entire market.

"Thank you, professors, I have an idea."

Chen Yu was a little excited.

He wants to perfect the idea just now.

"Let me take my leave first, thank you professors, I will visit you next time."

"Okay, go get busy. If you have anything to do, come to the school to find us at any time."

After speaking, Chen Yu left in a hurry.

"Old Li, do you think Chen Yu's idea can work?"

"How would I know."

Li Biqing smiled and shook his head: "However, I am looking forward to it."

"So are we."

Several professors glanced at each other, all looking forward to it.

Although they know the chance is not great, if they don't do it, then there is no chance at all.

……

"Yi Fei, Wu Kai, come to the office."

"By the way, invite some of our experts over."
