"Why, Chen Yu, I'm in trouble. ”

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

"It's not a problem, it's just that some ideas can't be figured out. ”

"Oh, tell me. ”

Chen Yu is also not modest.

Today he came to Li Biqing just to hear their thoughts.

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

"Hmm. ”

Everyone nodded and motioned for Chen Yu to continue.

"However, as Dean Li said on the phone just now, our mobile phones actually don't have much technical content. It may sell okay now, but in the future, there will be a lot of competition, and there will be pressure. ”

Saying this, Li Biqing also nodded: "Mobile phones are a big market, and major mobile phone manufacturers will definitely do their best." Your Tianyu mobile phone can be regarded as stealing a handful of chickens, but when they recover their strength, they can also sink into the low-end market. In addition, there are some foreign mobile phone giants, and the pressure on your future survival will be very great. ”

"So, we just wanted to do something technological. ”

"The child can be taught. ”

All three professors nodded their heads.

Sooner or later, things that have no technical content will be eliminated by the market.

"So you want to work with the school to do something technological?"

"Yes. ”

"That's a good idea, you donate some money to the school, and we will set up a research room, what do you think? ”

"Okay, no problem. ”

Chen Yu readily agreed.

Of course, it's okay to donate money.

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

But......

At this time, Li Biqing continued to ask: "Chen Yu, haven't you asked which piece of technology you want to focus on?"

"Chips. ”

"What......"

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

"Chips?"

Li Biqing looked at Chen Yu and asked.

"That's right. ”

Chen Yu nodded and said very seriously.

"This, this ......"

Li Biqing was a little embarrassed.

"Dean Li, what's wrong?"

"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." ”

"Ahem......"

Li Biqing coughed heavily: "You kid, make fun of us." ”

Seeing Chen Yu say seriously, Li Biqing glared at Chen Yu.

Chip technology.

Not to mention their Shencheng University, even Peking University and Tsinghua University, they are also extremely embarrassed.

Of course, not only domestic, but also in the world, except for a few countries in Europe and the United States, other countries do not have any chip technology.

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

Chen Yu was not joking, and then said: "In fact, before entering the mobile phone market, I was thinking about this aspect. When it comes to mobile phone technology, the strongest thing is the chip. However, our mobile phone chips have always been subject to foreign manufacturers. There may not be anything to see now, and when the future becomes bigger and stronger, sooner or later it will be constrained by them. ”

Chen Yu said truthfully.

"Chen Yu, you can see far enough. ”

Hearing Chen Yu say this, Professor Liu on the side said with a sigh.

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

Don't look at the rapid development of the domestic electronics industry, but to be honest, there are not many that really have technical content.

Many mobile phone manufacturers are actually assembly companies.

Even if it's Lenovo, there aren't many real technologies.

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

"Far indeed. ”

Li Biqing nodded: "How do I feel that this kid of yours wants to talk to the international mobile phone giant Pk." ”

"Dreams always have to come true. ”

Chen Yu is not yet available.

"I 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 difficult to talk about chips." ”

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

"How can I say it......"

Li Biqing hesitated for a moment.

He had some that he didn't know what to say.

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

Of course, this is an exaggeration.

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

Even, in some ways, more difficult than astronautics.

After all, the aerospace field has been researched since the founding of the country, but the chip has only been paid attention to in the past ten years. Whether it is technology or theory, there is a gap of decades between it and foreign countries.

Otherwise, how can we not even make a Chinese core in China now.

Speaking of which, this is a very embarrassing thing.

Even if Chen Yu jokingly said just now, it won't be that Shencheng University can't do it.

To put it mildly, I really can't do it.

"Chen Yu, I'll tell you about the chip manufacturing process first. ”

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

"If you want to build your own chip, the first step is the chip architecture, that is, the 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 figured it out a long time ago. ”

Li Biqing shook his head: "Okay, don't talk about anything else, just talk about this chip architecture." If you want to make a chip, the first step is to get the design out. If the architecture can't be figured out, then there's no need to talk about making chips at all. ”

"Chip architecture, also known as instruction set, is a command that instructs a 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 oriented to the PC, and Intel technology is the most mature. ”

"The second is the MIPS architecture developed by Stanford University in the United States, which is the same as Arm, they mainly do not produce chips themselves, and if chip manufacturers want to produce MPIS licenses, they can buy MPIS. ”

"The third is the powerPC architecture developed by IBM and Apple, and Mocarola, which is an architecture for the server market, and it is not useful for you for the time being. ”

"The fourth is the ARM architecture, which is also the most used architecture for 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.

"So we can't even take the first step right now?"

Chen Yu asked.

"The same cannot be said. ”

Li Biqing shook his head, but nodded again: "It's not that it's completely impossible, but there are still difficulties in this aspect to really make a mature architecture." ”

Saying this, Chen Yu understood.

Even if it is combined with the top professional research in China for several 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, then it's not much fun.

"At present, the domestic side of the chip production is biased towards buying mature architecture solutions, and then making appropriate modifications to make our chips. But even so, it is still difficult for us to make a more mature chip. On the one hand, our technology is limited, and on the other hand, these chip architecture companies do not license the top chip architecture to us. All we can buy is the low-end chip architecture. ”

This piece Chen Yu is even more sympathetic.

In the previous life, when ARM was awesome, it sold dozens of architecture licenses a year.

But each of them is different.

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

Undoubtedly, the design of Apple and Qualcomm is more awesome, and Huawei's is not bad, but it is still a little worse.

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

"It's not an option to buy. ”

Chen Yu shook his head: "Buying a chip architecture license seems to solve a 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 as well. ”

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." If you buy someone else's, it will get stuck in your neck from time to time. ”

"Now you know why it's so hard to make chips. ”

Li Biqing said helplessly.

In fact, this is just the chip design.

There are still many problems in chip production.
