Rebirth: I carry a desktop computer inside me

As soon as the ACM qualifiers were over, Jiang Cheng also felt relieved.

Although it is said that there is a powerful plug-in for the computer in the body, I have to admit that there are still many cows and gods under the sky.

Even if Li Zhengtao lost, they were also runners-up.

It is completely based on its own strength to make the topic.

No wonder the classmates called him "Tao Shen".

Of course, what Jiang Cheng didn't know was that after they won the Jinmen Division Championship, they had already been called "Jiang Shen".

Jiang Cheng, who returned to Mizuki, did not rest and continued to start his own chip design business.

Starting from a simple switching circuit, Jiang Cheng has mastered and understood the circuit principles of important components such as adders and subtractions, registers, etc.

But when it came to designing a small chip, Jiang Cheng felt the weakness of his own strength.

The design of a chip must have design documents and protocol documents at the beginning.

Have an architect to determine which parts of the protocol can be implemented in software and which parts need to be implemented in hardware.

Then there are the algorithm engineers, who have to choose the algorithm that implements the requirements according to the requirements.

In addition, there must be chip design engineers, described as RTL; Chip verification engineer, functional and performance verification of RTL....

Of course, under today's social division of labor, Jiang Cheng does not need to fight the world alone.

After design, there can be a special foundry company, which can be foundry, packaged, and have a special verification company to measure performance.

Now, what he's doing is designing a battery charge management chip.

This is a small chip.

But it is also a chip that has been very useful in recent years.

Jiang Cheng chose it after careful consideration.

In EDA software, Jiang Cheng began to write logic circuit code.

He needed to design a four-switch buck-boost, buck-boost converter.

This is a single-tube non-isolated DC converter in charge management with an output voltage less than the input voltage.

Jiang Cheng needs to make the battery fully charged faster through a more reasonable design and charging management of low voltage and high current.

Yes, Jiang Cheng now intends to design flash charging technology similar to "5 minutes of charging, 2 hours of talking".

Jiang Cheng thought to himself.

This advertising message is very good, I want it!

However, this kind of IC chip design and manufacturing is fine, but CPU chip design is not an easy task.

Even if a hundred million is invested, it is difficult to bubble up many bubbles.

Optical architects, the annual salary is 40W starting at 40W.

Not to mention the purchase of ARM architecture authorization, it is another million meters to start....

If you plan to develop your own architecture, you must be able to bypass the existing patents, and you will also face the dilemma of not having an ecology in the later stage.

The money prepared by Jiang Cheng only registered one Maple Fire Semiconductor Co., Ltd.

Even the venue has not yet been implemented.

He plans to use the internal computer to develop and design first, and then consider setting up a chip research and development laboratory after it is more mature.

Whether it is a mobile phone or a desktop-level CPU, these chips are even more difficult.

Jiang Cheng can only start with a simple chip.

The battery charge management chip is Jiangcheng's starting design product.

---^_^o~ Effort! -----

class of the School of Microelectronics, Jiang Cheng audited it for the first time.

There were not many courses in his senior year, and Jiang Cheng did not spend a lot of time to complete the preliminary self-study.

Now, his focus is on software development and chip design and manufacturing.

One is software and the other is hardware.

In terms of software, Jiang Cheng is currently updating the Maple Fire PE special effects production software, and he will sort out a version to launch on the market for commercialization (of course, the best version belongs to his own company);

In terms of hardware, Jiang Cheng is ready to design and manufacture battery charging management chips.

In the computer science department, Jiang Cheng has learned a lot of low-level circuit knowledge, but his in-depth understanding of the hardware layer is still not enough.

When he arrived at the Department of Microelectronics, Jiang Cheng felt another kind of boring.

Mode electricity, number sets, modular sets, semiconductor devices, semiconductor physics...

It's all full of dry goods.

Make people's brains swollen.

Fortunately, Jiang Cheng brought a computer in his body.

These underlying logic circuits can be better understood.

How do you rub a handful of sand into I9 9900K?

From purification to wafer, from lithography and etching, to packaging and verification.

This series of technological processes also involves materials, chemistry, physics and many other disciplines.

Modern science is extremely comprehensive and has a strong division of labor.

Can Jiang Cheng alone learn all the knowledge?

Even Jiang Cheng himself sometimes doubts.

"Classmate, you're not our major, are you?"

Just as Jiang Cheng finished listening and was about to leave.

A man wearing glasses sitting next to him patted him on the shoulder and asked.

Jiang Cheng said honestly, "I am a computer to understand the knowledge of mode electricity and semiconductor physics." "

Really," the man looked suspicious, "didn't you come to chase our girls?" "

Jiang Cheng looked at it at a glance, although the number of girls was more than that of the computer department, it was also less." No, no, I have a girlfriend.

"Well, there are not many girls in our department, so you don't want to grab resources anymore." The man warned solemnly.

"...,"

the man stretched out his hand again, "My name is Wang Xiaogang, do you know me?" "

Computer Department Jiang Cheng."

"Your family rarely comes to us, you are the first I have seen." Wang Xiaogang looks good, that is, his hair is a little non-mainstream, he is a little long, and when he speaks, he likes to raise his head and let his hair show.

Jiang Cheng is very modest, "It's just curious, I don't know if microelectronics are good to learn."

"Brother Jiang, you must dispel your curiosity." Wang Xiaogang spoke a little seriously, "Let me tell you, we have studied too much in our majors, what semiconductor physics and devices, solid state physics, microelectronic processes and so on." Hardware must be learned, software must also be learned, and people feel like listening to heavenly books every day..." Jiang

Cheng nodded, indicating understanding.

No wonder you sit in the back row like this.

"Alas! The difficulty of mold electricity is difficult to go to the sky. Integrated or enlarged, how dazed are the eyes..." Wang Dagang shook his head and sang a poem, his face was indignant.

"Well, it shouldn't be so difficult, I feel that this self-study time is not bad." Jiang Cheng was a little speechless, and he made up songs.

Wang Dagang hummed, "The content in this book is one thing, but the title is not that. Young man, you are still young, don't raise it. "

Understood." Jiang Cheng accepted it humbly. Just the feeling of buyer show, seller show!

The two talked for a while, and Jiang Cheng also asked a lot of information.

For example, which teacher is the most awesome, which course is the most difficult, which direction is the most promising, and so on.

After some conversation, the two became more familiar.

"Brother Wang, I want to go to the Institute of Microelectronics, I wonder if there is any way?"

Wang Xiaogang hated that iron could not become steel, and said very formally, "Your family's future is so bright, why come to my microelectronics to find hardships." "

......

"It's not what you think, I want to learn to design chips." Jiang Cheng explained.

"Then don't come and learn, you guys are engaged in software, just understand it." Wang Xiaogang said, "But if you really want to see and see, we have an SRT project in the work, I can take you in to see." Jiang

Cheng never thought that this was also a big guy, and he felt disrespectful.

"Brother Wang's SRT project?"

"Hey, I just mixed up with the big guy." Wang Dagang smiled and looked at his watch again, "Go, I'll take you to the research institute." While

speaking, he pulled Jiang Cheng and left.

Jiang Cheng was really interested in the institute, followed the big guy, and soon entered the institute.

It is not the same as Jiang Cheng's imagination, the feeling of being very high-tech, after entering the institute, it feels similar to the style of most scientific research institutes.

And this is an old building, some old.

Wang Xiaogang said, "Just follow me around, the project can't take you in." "

Understood."

Just after speaking, a few men came around the corner.

"Xiao Gang! Why did you bring unrelated people in again? The man who took the lead looked cold and asked sharply.
