Super entertainment red envelope

Chapter 821 What is Li Zhifan going to do?
"Come, come, Brother Zhifan, come and taste my Dahongpao."

As soon as he was seated, Lei Shanhe pushed the teacup in front of Li Zhifan, very cordial.

"Boss Lei!"

Li Zhifan also greeted him with a smile, "Now that the technology circle is so turbulent, the major media are reporting on you, but you are a very busy person, how can you have the time to ask me out for tea?"

"Hey, it's not about the endorsement contract!"

Lei Shanhe said bluntly, "I will not hide our friendship and relationship. The company has encountered great difficulties now, so I hope to renew the contract for two quarters first. If your new product can turn the situation around and renew the contract later, I will definitely not lose you, and the endorsement fee... Can you refer to last year's price?"

These words were addressed to Li Zhifan, and also to Liu Zexin who was at the side.

As a manager, Liu Zexin handles everything related to the endorsement. Besides, Li Zhifan is not eating alone now, and it is useless for him to nod alone. We have to proceed and consider the overall situation, and we cannot ignore the people behind him for the sake of temporary loyalty everyone.

However, Lei Shanhe's conditions were not very harsh. After some bargaining, the endorsement contract was renewed and finally signed.

After signing the agreement, Li Zhifan asked Lei Shanhe, "Boss Lei, is the chip a headache?"

"Yes!"

As soon as this topic was mentioned, Lei Shanhe began to be longer than short, "Oh! This is not my own core disease, but the national core disease. If we can independently develop and mass-produce it, then the cost of each mobile phone will be reduced. It has dropped a lot. You know, there are more than 20 kinds of large and small chips in each mobile phone. Take the Touch currently under development as an example, there are 12 types that need to pay intellectual property fees, of which only the baseband processor chip and the GPU chip. It needs to be purchased from abroad, so the cost of a mobile phone has increased by about 400 yuan. Using our own developed chips can completely save this cost, but the performance of the currently developed chips is too low, not as good as foreign chips five years ago .”

Li Zhifan summed it up in one sentence: "In conclusion, the baseband processor chip is a problem, right?"

"Yes, it is!"

Lei Shanhe said, "But I'm still very optimistic. At least our technology is constantly improving. Although the performance of independent research and development is low, it must be improved! It's like a domestic car worth 4 yuan. In the past, you You have to take a taxi, or sell imported cars to pay a lot of tariffs, but now with this 4 yuan domestic car, at least more people can afford to drive.”

"I understand the truth!"

Li Zhifan smiled, "Hey, Mr. Lei, I have an unfeeling request. I wonder if you can agree?"

"Say it!" Lei Shanhe waved his hand, he didn't think Li Zhifan would make any particularly difficult request.

"I want to see the detailed information of all the most advanced CPU and GPU chips in the world, especially the intellectual property technologies involved in each of their chips. It would be best if you can provide me with detailed algorithms for every detail. But!"

After Li Zhifan finished speaking, Lei Shanhe stared: "What are you doing? You don't want to plagiarize it for some research institution, do you?"

"Plagiarism?" Li Zhifan was taken aback, "No, no, no! No way!"

He thought to himself: Even if he wanted to copy, he would not copy from this world!
"Using other people's films to decipher plagiarism, there is basically no market at all, either in the name of scientific research, or in the name of national defense, or purely cheating money!"

Lei Shanhe said, "So when we develop our own chips, even if we have to, we can only buy foreign architectures, and then we develop Socs independently on this basis. Plagiarism is not allowed."

"I know!"

Li Zhifan explained, "I'm not in your line of business, I'm just doing research. After I figure it out, I plan to make a documentary, and I may go to Mr. Lei's company to shoot scenes at that time, so don't let it go! "

"Oh? Oh! Oh..."

Lei Shanhe made a surprised expression three times, and then he suddenly realized - Li Zhifan is a person in the entertainment industry, how could he know about technology, well, it seems that he was thinking too much.

"OK then!"

Lei Shanhe smiled wryly, "I'm confused when you say that, so I'll prepare it for you, but some of the information is top-secret, and the original company didn't open source it or spread it outside."

Li Zhifan said regretfully, "Uh, so it's just incomplete?"

"Haha!" Lei Shanhe smiled mysteriously, "Of course we can get it all, don't worry! I can get you whatever you want to see, and I will send it to your email in two days!"

"That's good!" Li Zhifan still instructed, "Boss Lei, do what you can and don't break the law!"

"No! No!"

Lei Shanhe's smile was even more mysterious, and he was even more sure that Li Zhifan was a rookie who didn't understand anything in the technology industry.

In fact, not only in the technology circle, but in today's society, there are no secrets that are completely kept secret, only to whom and at what price.

If it were to be announced directly to the whole society, there would be many more people involved in compensation and various links, and it might even be traced back to the top of the original company.

In this society, there is a kind of person called a commercial spy. In their hands, all betrayals are reasonable, even if he has reached the position of president, CEO, or chairman of the company, as long as he is not the company's major shareholder Professional managers who receive annual salaries and share dividends are one of them.

……

Two days later, Li Zhifan received an email from Lei Shanhe.

I thought it would be a small amount of data, but I didn't expect it to be a file of nearly 23 G.

The three most basic components of a CPU are the control unit, the computing unit and the storage unit.

Subdivided, it is divided into CPU architecture, core frequency, GPU, memory, and baseband. But in addition to these five items, there is another item that is the manufacturing process, that is, the CPU process, commonly known as size, and the unit is nanometers.

Reducing the core area of ​​the chip can bring lower power consumption, but the technical difficulties are also very high, especially the material, the underlying structure of the transistor, and the technical physical and performance limits must be overcome to achieve these.

The current mainstream chip in the world is the 5nm LPE process, especially the three cutting-edge CPUs, namely the "K2-17" developed by Bailey, the "Fst0301" developed by Foster, and the "Dingdian 798" developed by Dingdian. , are all using the 5nmLPE process.

Among them, "K2-17" is the most outstanding chip currently used in iRon series mobile phones, which is also the world's mobile phone sales champion. Its technology is jointly developed by iRon and Bailey Technology, so this chip is only used in iRon's mobile phones superior.

The second is Fst0301, which is the fixed chip used by most high-end flagship phones at present, especially the major domestic mobile phone manufacturers, such as Touch phones, not only high-end flagship phones use Fst0301, but also low-end phones use Foster FstA023, another low-end chip, is a castrated version of Fst0301.

As for "Dingdian 798", it is generally used in low-end machines, which is comparable to Foster's FstA023. The market is pretty much all-inclusive.

But what Li Zhifan wants to study is not just these three chips, but all the current chips in the world, including chips that are being developed by foreign chip companies.

Even the chips under development cannot be separated from the architecture and technology of the company's previous generation of products, and those intellectual property rights will still be used later. Even if a certain intellectual property right may be completely replaced or abandoned in the future, at least for now , not much difference.

After three weeks, Li Zhifan finally finished reading these materials, and in his mind, he also formed a complete set of materials. If he wrote them out, he could directly compile a "History of Human Microchips".

The purpose of his research on these is because of an amazing plan-to manufacture real Chinese cores!
In the eyes of industry insiders, this plan is a world-class problem, and it is completely nonsense when it comes to Li Zhifan.

how can that be possible?
You are an artist!
Even if you can play on a computer, can you program?Do you understand?

Yes, Li Zhifan may not understand it before, but it doesn't mean he will never understand it.

Moreover, he was worried about such rumors, so he didn't tell anyone about it, but started a project that was similar to building a car behind closed doors.

First is the hardware.

Li Zhifan directly spent 2500 million yuan. He rented a warehouse of more than 100 square meters in Zhongguancun, Beijing as an office, and assembled five engineer-level computers. The total cost of assembly cost more than 230 million yuan.

Once the hardware was finished, Li Zhifan started his lonely development journey.

Even bringing chips from another world is not an easy task, because in some details, it is very possible to cause similarities, which will constitute infringement, so Li Zhifan can only take them apart. , a step-by-step operation.

The first is architecture.

The CPU architecture of this world is currently controlled by the three major international semiconductor intellectual property suppliers, and firmly occupies the entire civilian CPU architecture market.

Of these three major suppliers, one is in the UK, one is in Sweden, and the other is in the United States. No matter which CPU architecture is used for domestic chips, it is to make money for foreigners. It is too difficult to independently develop the architecture because of compatibility issues. At present, whether it is in the field of computers or electronic products, it is only compatible with these three suppliers.

At first, Li Zhifan thought it was a headache.

But after getting the architecture from another world-named ARM supplier, I couldn't help but be surprised!
This structure is completely different from the three major structures of this world!
In the other world, more than 95% of smartphones and tablets use the ARM architecture, which shows that this architecture is mature and sophisticated enough.

However, whether this architecture can be used and compatible with all operators in the world is the most important issue.

But if it is not produced, it will never be sorted out after practice. Li Zhifan immediately got into the carrying work.

For the production of China Chip this time, Li Zhifan absorbed dozens of computer skills books, and the red envelopes of these skills books all came from technology experts from other worlds.

Even if he starts research and development now, Li Zhifan will still use AI technology to enter another world every night, and stay in Zhongguancun, grabbing the red envelopes dropped by those technology R&D personnel.

As for the porting of the ARM architecture in another world, it is actually a wrong thing.

When Li Zhifan had strong computer skills, he suddenly discovered that there were stores of major technology companies in the mall, such as Intel, ARM, Apple, Samsung, Qualcomm, Huawei, Xiaomi...these companies all have them, and they can be bought directly. to their core technology.

Of course, if Li Zhifan did not have the prerequisites for learning and absorbing skills, even if he had these technical red envelopes, he would not be able to use them.

……

A month later.

Li Zhifan finally got the test of the ARM architecture, and he is also preparing to learn the strategy of ARM, that is, ARM itself does not rely on its own design to manufacture or sell CPUs, but licenses the processor architecture to interested manufacturers.

Therefore, Li Zhifan intends to set up a special authorization company called Zhuofan Architecture Co., Ltd.

Zhuofan will provide a variety of licensing terms, including items such as price and dissemination, and each manufacturer gets a unique set of related technologies and services.

For the authorized party, Zhuofan Architecture Co., Ltd. provides an integrated hardware description of the kernel, including complete software development tools, and the right to sell CPU chips containing Zhuofan architecture.

Of course, it is hard to say whether Li Zhifan will set up another company to produce chips. This will attract more chip manufacturers to become partners.

January.

Li Zhifan posted a poster on Kuaibo, the background color of the poster is black, and there are two gold characters on it - Zhuo Fan!
There is a line of small white characters below - 2023 Zhuofan Technology Conference / October 10th!
Next to the small white characters is Li Zhifan's handwritten signature.

Many netizens couldn't understand this poster when they saw it, and they were confused: What is Li Zhifan doing?
Technology?

Could it be that he did something?
Smart camera equipment?

Smart unmanned playing electronic musical instruments?

Now when it comes to technology, emerging industries such as unmanned driving, VR/AR, and artificial intelligence are inseparable. However, in terms of the most basic civilian CPU architecture, it is automatically ignored because of its weak strength.

But with the little news released now, even if the netizens guessed their heads, they still can't guess what Li Zhifan is going to do, and what technology-related things he has done!
……

Ray's Group.

Lei Shanhe ate and walked around wearing socks on the thick carpet.

Since Li Zhifan came to the door a week ago and showed him the Zhuofan structure, Lei Shanhe was completely stunned, shocked, terrified, and subverted his cognition.

What kind of monster is this?

In such a short period of time, with the strength of one person, he actually developed a unique and exclusive CPU infrastructure?

How can it be?

How can it be achieved?

And Li Zhifan came to his door with two requests. One is that the chip research and development team under Lei's Group can help test this infrastructure, and the other is that Lei Shanhe can help him organize a press conference.
