Siheyuan: Starting from a fitter

Chapter 308 The Birth of Core i1
As soon as the rewards were handed out, Representative Luo blocked Li Guocheng into the office.

"Old Li, you have been away for a month or two, do you know how I have lived this year?"

"Okay, Lao Luo, you are a fool and I am me. We have nothing to do with each other," Li Guocheng joked.

"Bah! Just tell me, when will you surprise me?" Representative Luo understood anyway, this person had to force him, otherwise he wouldn't know where he would run to again.

"Look, I just came back. I have a lot of things. How can you tolerate me for a while? I will definitely let you see it for a month at most."

"Keep your word, or I will stay in your office." Representative Luo was willing to give up.

"I'm afraid of you, don't worry, your matter has the highest priority now." Li Guocheng felt that it was a bit outrageous, and he had pushed it for too long.

Representative Luo, who had received the promise, suddenly became obsessed, "I heard that you change female stars every day in Xiangjiang?"

"Get lost!" Li Guocheng became angry in embarrassment.

Representative Luo jumped up and ran away. Li Guocheng looked at it and smiled, "Damn, it was passed pretty fast."

Li Guocheng thought for a while, whether it is a notebook now or a "surprise" in the future, CPU performance is the key. Using KT32F7400 in Kunpeng [-] is too advanced and inappropriate.

Moreover, the definition method is based on the Shuguang Kaitian series. Now that Longhua Technology has been established, it is no longer appropriate to continue to use the past numbering method.

The core is still based on the ARM architecture, and Li Guocheng is preparing to redesign a CPU chip.

After Ertein launched the 80386, other manufacturers also developed compatible CPUs based on the X86 architecture, and motherboard manufacturers also developed compatible motherboards.

Domestic products are mainly Kaitian series, such as the latest KT32F105.In order to improve the compatibility of domestic CPUs, it seems that it is recommended to set up a special standardization organization.

Otherwise, when facing competition in the future, it is easy to be defeated one by one.

Thinking of this, he thought of a name similar to X86. As an engineering student, he was really not good at naming. In the end, he simply used the Core after Ertein X86.

Go your own way, leaving nowhere else to go.

First version chip name: LH Core i1 01 240
The naming rules are as follows:

LH represents Longhua Technology brand;

Core chip series;

i1 chip level, the lowest level;
01 represents the first generation;
240 means the main frequency is 240MHz.

The main purpose of this chip is commercial office, scientific computing, engineering design, multimedia processing, etc.

管脚定义和鲲鹏2000使用KT32F7400兼容，和KT32F105基本兼容，只是在小部分管脚上定义不一样。

The main difference is that the pins are added, but the incremental method is adopted, and the pinholes reserved on the motherboard can be compatible with Core and Kaitian series CPUs.

The performance characteristics of this product are that the main frequency is increased to 240MHz, and an image processing module and a power management module are added inside, which can improve image processing capabilities and save power.

The main functions and performance are determined, and combined with the gains from this trip to Silicon Valley, the new CPU will beat all current ones.

The laboratory purchased the latest parallel server from the National Semiconductor Research Institute, and he directly used EDA software to design the chip. Although it runs slower, the advantage is that the technology can be passed on.

He originally designed the chip in his mind, and the output was a mask engraved by his own hands, which could not be passed down.

Although I had an idea, it still took 3 months to design the chip.This is also Li Guocheng. If it were someone else, such a complicated chip would not be completed in half a year to a year.

When I saw the mask manufacturing equipment that Yan Jiefang was operating, my heart collapsed.

Every time he moves the engraving knife, he needs to measure it repeatedly. When moving the knife, he also uses a magnifying glass to look at the scale to avoid moving the knife too far.

"How long does it take you to produce a mask?"

"It's as complicated as yours. It's estimated to take more than 3 months, and it also depends on the number of scraps. If there are too many scraps, a year is not impossible."

Yan Jiefang saw Li Guocheng's dissatisfaction and explained weakly.

Forget it, you can go to Master Yi and ask him to help you design a three-axis precision CNC machine tool.The engraving can be replaced by laser, I will help you with this.

Currently, he has no choice but to continue carving the mask manually.

A week later, the mask plate was engraved and handed over to Yan Jiefang to help manufacture the chips.

He hurriedly began designing 'surprises'.

In fact, it is a remote control handle with a 12-inch LCD screen.

The circuit diagram design is relatively simple, the only difficulty is CPU heat dissipation.

Thinking that this is for military use, the usage environment is very harsh and fans cannot be used.Therefore, the shell of the remote control is made of aluminum. The CPU is directly attached to the shell, and the entire shell is a radiator.

For aesthetic reasons, the front and handle are made of plastic and have an all-black design.

Another half month later, the development of the new remote control and display all-in-one machine was completed, and a total of 5 prototypes were made.

At the same time, he wrote a proposal for the establishment of a semiconductor standardization organization and handed it over to Representative Luo.You can't look for Mr. Zhao for everything, that would make him appear too incompetent.

After dealing with these matters, Li Guocheng was ready to take a rest for the time being.As for how to promote his Core CPU, it was left to Wu Liankui.

Because he was preparing to build Longhua Computer Branch, specializing in manufacturing and selling commercial computers.

This time I visited Sfortan University in Sam Country, and saw a long wall of honor in the school history exhibition hall, listing professors and graduates who have made outstanding contributions.

There is also a display of the great achievements that Siftan University has made in the world's science and technology, humanities, education, etc.

It leaves every visitor in awe and inspires all faculty, staff and students at Sfortan.

Now that he has obtained the book and was inspired by Sfortan University, he wants to show future generations the scientific and technological wisdom of his ancestors.

So he made an appointment with the mayor of Kyoto and applied for a piece of land.

When Mayor Gao heard that Li Guocheng wanted to build an 'Ancient Chinese Science and Technology Exhibition Hall', he was very interested.

"Mr. Li, first of all, thank you for your investment in China, and thank you even more for building a laboratory in Kyoto City. I wonder if you can tell me more about the concept of this exhibition hall?"

"Okay, Mr. Mayor. The Ancient Chinese Science and Technology Exhibition Hall is divided into three areas. The first area is the ancient science and technology exhibition. It mainly restores the physical objects of ancient Chinese science and technology and allows the Chinese people to understand the splendid scientific and technological civilization of ancient China.

The second area is the conference hall, which mainly provides professional conference services for various social groups or organizations.

The Chinese Cultural Activity Hall in District [-] is mainly for student groups and provides them with a professional Chinese cultural activity venue.Competitions are held regularly and certain prizes are provided.

In short, the main purpose of the Chinese Ancient Science and Technology Exhibition Hall is to promote Chinese culture."

"Sounds very tempting, but I'm curious, why are you so persistent in promoting Chinese culture?"

"First, my ancestors are Chinese, and the blood of Chinese people flows in them; second, today's children are more interested in Western culture and have insufficient understanding of Chinese culture; third, only by recognizing the greatness of Chinese culture can people I will be proud of being a Chinese."
