Chapter 455

"Why, Chen Yu, I'm in trouble."

After introducing several professors to Chen Yu, Li Biqing looked at Chen Yu with a smile.

"There's no trouble, just some ideas don't work out."

"Oh, tell me."

Chen Yu is not modest.

Today, he came to Li Biqing to listen to their ideas.

"Dean Li, three professors, you must know that we have entered the mobile phone recently."

"Yes."

The crowd nodded and motioned Chen Yu to go on.

"However, as president Li said on the phone just now, our mobile phones actually have no technical content. They may sell well now, but there will be pressure in the future."

Li Biqing nodded: "mobile phones are a big market, and major mobile phone manufacturers will definitely try their best. Your Tianyu mobile phone has stolen a chicken, but when they slow down, they can also sink into the low-end market. In addition, there are some foreign mobile phone giants, you will have great pressure for survival in the future."

"So we just want to do something with technical content."

"Children can be taught."

All three professors nodded.

Things without technical content will be eliminated by the market sooner or later.

"So you want to cooperate with the school and do something with technical content?"

"Yes."

"That's a good idea. Later, you donate some money to the school. We'll set up a research laboratory. What do you think?"

"OK, no problem."

Chen Yu readily agreed.

Of course there's no problem donating money.

If you donate money, you can solve the problem. Chen Yu is willing to donate 1 billion.

But

At this time, Li Biqing then asked, "Chen Yu, I haven't asked which technology you want to focus on?"

"Chip."

"What..."

Not only Li Biqing, but also the three professors shook their hands when they heard Chen Yuyi say about the chip.

"Chip?"

Li Biqing looked at Chen Yu and asked.

"Yes."

Chen Yu nodded and said very seriously.

"This, this..."

Li Biqing was a little embarrassed.

"Dean Li, what's the matter?"

"No, nothing."

"Do you have to donate a lot of money to make chips?"

"Nothing..."

"What's that?"

Chen Yu asked weakly, "no, the school can't do it."

"Cough..."

Li Biqing coughed heavily: "you boy, make fun of us."

Seeing Chen Yu's serious remarks, Li Biqing glared at Chen Yu.

Chip technology.

Let alone Shencheng University, even Peking University and Tsinghua University, they are also very embarrassed.

Of course, not only at home, but also in the world, except for a few countries in Europe and the United States, there is no chip technology in other countries.

"No, Dean Li, I really want to make chips."

Chen Yu did not joke, then said: "in fact, before entering the mobile phone market, I was thinking about this problem. The strongest technology of mobile phone is chip. But our mobile phone chip has always been subject to foreign manufacturers. Now I can't see anything. It will be restricted by them sooner or later when we become bigger and stronger in the future."

Chen Yu said truthfully.

"Chen Yu, you see far enough."

When Chen Yu said this, Professor Liu on one side sighed.

As professors in the field of computer, they know this best.

Although the domestic electronic industry is developing rapidly, to be honest, there are not many with real technical content.

Many mobile phone manufacturers are actually assembly companies.

Even Lenovo doesn't have much real technology.

Not to mention chip technology, there are a series of other key technologies, which are incomparably weak in China.

"It's really far."

Li Biqing nodded: "how do I feel that you want to compete with the international mobile phone giant PK."

"There must always be dreams. What if they come true."

Chen Yu didn't say whether he could.

"How dare you think."

Li Biqing gave Chen Yu a thumbs up.

But after a while, he said very seriously, "however, Chen Yu, it's really difficult to make chips."

"President Li, I don't understand technology. Can you tell me more?"

"How to say..."

Li Biqing hesitated for a moment.

He doesn't know what to say.

Seriously, when it comes to chips, he doesn't know where to start.

Of course, this is a little 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 aerospace field has been studied since the founding of the country, but the chip has only been paid attention to in the last decade. Whether it is technology or theory, there is a gap of decades with foreign countries.

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

Speaking of it, this is a very embarrassing thing.

Even if Chen Yu joked just now, Shencheng university can't do it.

Say a very ashamed word, really can't get it out.

"Chen Yu, I'd better tell you the manufacturing process of the chip first."

To say how to make domestic chips, we really have to start with the technology of chips.

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

"This can be understood. It's like making a mobile phone and making a mobile phone design first."

"What do you understand? Do you think chip design is so simple? If it was so simple, we would have worked it out long ago."

Li Biqing shook his head: "well, don't say anything else, 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 made, there's no need to talk about making a chip."

"Chip architecture, also known as instruction set, 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 x86 architecture, which is mainly aimed at the PC, and Intel technology is the most mature."

"The second is the MIPs architecture developed by Stanford University in the United States. Like arm, they mainly do not produce chips themselves. If chip manufacturers want to produce, they can buy MPIS authorization."

"The third is the PowerPC architecture developed by IBM, apple and Motorola. This is an architecture for the server market. You can't use it for the time being."

"The fourth is the arm architecture, which is also the architecture most used by all kinds of 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."

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

So, Chen Yuming is white.

Even if it is combined with the most top professional research in China for many years, I'm afraid it can only make a simple chip architecture. And the chip architecture may be decades behind others.

If so, it's not interesting.

"At present, domestic chip manufacturers prefer to buy mature architecture solutions, and then make appropriate modifications to make our chips. But even so, it is still difficult for us to make more mature chips. On the one hand, our technology is limited, and on the other hand, these chip architecture companies will not license the top chip architecture to us. We can What I bought was just a medium - and low-end chip architecture. "

Chen Yu felt the same and deeply.

In the past, arm sold dozens of architecture licenses a year.

But each of their structures is different.

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

Undoubtedly, the designs of apple and Qualcomm are more awesome. Huawei's are also good, but they are still worse.

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

"Buying is not the way."

Chen Yu shook his head: "buying chip architecture authorization seems to solve the problem for a while, but it can be purchased now. What if they don't sell it in the future?"

"So there are problems."

Li Biqing also agrees with Chen Yu: "it may take a long time to do it by yourself, and even if you do it by yourself, you may not be able to produce a mature design. If you buy someone else's, you 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.
