The rejuvenation of a great nation: from educated youth to national treasure scientist

Chapter 129 The world's computer development pattern will be broken
In fact, Wang Haoran did not spend too much time on the project of large-scale programmable switching system.

After the 24-door programmable switching system was developed, other team members Qian Dake and Xiao Renming had basically mastered the methods and ideas for developing other types of switches.

Wang Haoran only needed to give some simple instructions, and the team led by two people could start working.

Wang Haoran himself turned his attention to electronic computers again.

It took him two days to finally write the project application report.

In fact, the current development of electronic computers in China is not particularly backward.

In this era, Longguo's scientific community still has a large number of outstanding scientific and technological talents.

They developed Longguo's own computer model, and electronic computers have been widely used in scientific research.

However, one thing that needs to be explained is that Longguo’s current computer models are generally used for various complex logical operations, and there are no application functions such as office document software and design software.

Moreover, computers are now basically all produced by hand, and even the circuit diagrams are soldered on manually one by one.

This also makes Longguo's domestic electronic computer production efficiency extremely low, with annual output of only a dozen units.

What Wang Haoran wants to change now is actually the fatal problem of backward production methods.

He wanted to transform Longguo's electronic computer production into truly modern large-scale machine production.

He wants to develop document editing software and design software.

He wanted to create a true microcomputer.

As I said, there is really no shortage of capable people in Dragon Country nowadays.

In April 1977, Tsinghua University, Anhui Radio Factory and the 4th Institute of the Ministry of Electronics jointly developed a microcomputer DJS-6.

This computer is said to be the first microcomputer in the true sense of the Dragon Country.

Its CPU is 8-bit and its appearance is quite similar to that of later computers.

But even such a computer product is mainly used for various computing tasks.

In Wang Haoran's own research project application report, he defined his research topic as "Research on modern production lines for microcomputers."

The main contents he wants to study are divided into software and hardware.

The software mainly includes operating system and application software.

However, research on operating systems is still very difficult.

After all, since it is a domestic operating system, it must use a Chinese system. However, the total number of Chinese characters is as high as tens of thousands. Under the current hardware conditions with very limited computing speed and storage capacity, it is quite difficult to create such a system.

But this is actually not difficult to solve for Wang Haoran.

In terms of computer hardware, the most core hardware CPU has been solved.

Pangu 1 CPU is still quite advanced.

With the completion of the entire chip industry chain, the production of CPUs will no longer be a problem.

Now, Wang Haoran needs to do the following work in terms of hardware:

First, continue to launch more advanced Pangu architecture CPUs.

Second, we need to develop more advanced memory chips.

Third, we need to design and develop graphics card chips, or GPUs.

Fourth, other supporting chips need to be developed, such as the south bridge chip and the north bridge chip, which are important components of the motherboard. The north bridge chip is mainly responsible for communicating with the CPU and providing support for high-speed devices, etc. The south bridge chip is responsible for communicating with high-speed devices such as USB ports and PCI slots...

Fifth, the computer’s mechanical hard drive is also a big technical difficulty and must be solved.

The sixth is to get the computer motherboard. However, after getting the above, the computer motherboard is not a big problem. After all, the PCB production line is mature and can completely process and produce computer motherboards.

For modern computers, the hardware mentioned above is actually the core technology.

For Wang Haoran, who has a biochip memory capsule in his brain, the design of these chips will not be a problem at all.

Moreover, the material foundation for researching microcomputer production lines has basically been laid.

For example: computer motherboards can easily use the current PCB circuit board production line, and chip production is basically not a problem.

In fact, after all, software is still a tough nut to crack.

Wang Haoran submitted his project application report to the Fourth Ministry of Machine Building again.

There is no way around it. The field of electronic computers is still under the jurisdiction of the Fourth Ministry of Machine Building.

After Wang Haoran submitted his project application report, it was quickly noticed by Lin Xiangyang, who was in charge of scientific research project approval.

After Lin Xiangyang finished reading it, he frowned.

Wang Haoran wants to study electronic computers?
However, a new type of electronic computer has been developed in China.

The DJS-050 microcomputer was just approved in April 1977. This microcomputer is very easy to use in all aspects and is currently being produced for use by major scientific research institutions.

Wang Haoran also wants to study electronic computers, so is this duplication of research?
However, judging from the contents of Wang Haoran's research project application report, the microcomputer he wants to study seems to be very different from DJS-050.

Lin Xiangyang took Wang Haoran's project application report to see Guo Weiyang, the head of the Fourth Ministry of Machine Building.

After reading Wang Haoran's research report, Guo Weiyang said, "I think Comrade Haoran's research topic is quite interesting."

"What he wants to make is an application-oriented microcomputer. This kind of computer can be used to create spreadsheets, edit documents, and create presentation documents. Hmm! From what he said, it can also help scientific research institutions and construction units to design and draw design drawings and construction drawings."

“I think this is great!”

Lin Xiangyang said: "Leader, the key point is: I think his research will not have a large scope of application in the future..."

"As you know, our domestic electronic computer production is very slow. A factory can only produce a few products a year. The cost is too high and it is not suitable for popularization at all."

Guo Weiyang nodded and said, "The current production efficiency is indeed very poor."

"However, according to Comrade Haoran's research application, if we can use a highly efficient production line to produce microcomputers, the production cost will probably drop exponentially! The output of microcomputers will also increase rapidly, just like our domestically produced color TVs!"

"I think this topic is very meaningful! It should be listed as a key topic of our Fourth Machine Department!"

Just like that, Guo Weiyang made the decision.

……

Lin Yuanchao is a famous professor in the Department of Computer Science at Tsinghua University.

He was also one of the main participants in the research of DJS-050 microcomputer.

He and his team are mainly responsible for the development of 15 types and 40 small and medium-scale integrated circuits.

In fact, this DJS-050 microcomputer mainly imitates Intel's 8080 series microcomputer.

The two are even compatible.

After Wang Haoran stood out, Lin Yuanchao has been paying attention to him.

He watched Wang Haoran build a PCB circuit board production line.

He watched Wang Haoran develop a chip production line with a complete industrial chain.

He watched Wang Haoran develop the Pangu No. 1 CPU, which was more advanced than the one he had led in developing.

To be honest, Lin Yuanchao was very surprised.

At the beginning, he was also invited to join Wang Haoran's chip production line project team.

However, Lin Yuanchao refused at that time.

Because he had more important tasks at hand at that time.

His research project is to develop a newer and more user-friendly microcomputer.

During his research, Lin Yuanchao also tried to use the Pangu No. 1 CPU developed by Wang Haoran. After using it, he felt that it was indeed very easy to use.

Lin Yuanchao's new microcomputer is almost ready.

But at this time, he saw that the Fourth Ministry of Machine Building had approved Wang Haoran's new project.

And Wang Haoran’s new topic is to research a new type of microcomputer production line?

Lin Yuanchao was immediately a little annoyed.

He thought to himself: What is this?
My new computer is almost finished, and you're going to start work on it too?

This is a typical case of you stealing credit!

Lin Yuanchao immediately went to find Guo Weiyang, the head of the Fourth Machine Department.

"Leader, I really don't understand!" Lin Yuanchao said to Guo Weiyang.

Guo Weiyang smiled and asked, "What don't you understand?"

"Far beyond comrade, just say it directly."

Lin Yuanchao said: "My team is researching a new type of microcomputer, and we are basically close to producing results."

"Now it's good. Wang Haoran is also going to do almost the same project."

“Isn’t this a serious waste of resources?”

Guo Weiyang suddenly realized: "So this is what you are talking about!"

"Comrade Haoran's research is somewhat different from yours. He focuses on the research of modern microcomputer production line equipment. And you are researching microcomputers themselves."

Lin Yuanchao said angrily: "Leader, don't be fooled by appearances."

"If he wants to build a production line, then he must also develop computers!"

Guo Weiyang frowned and said, "The Third Plenary Session of the 18th CPC Central Committee has already been held. We need to reform and introduce market mechanisms in the future."

"And the most basic feature of the market is to allow competition to occur."

"Comrade Yuanchao, please carefully study Comrade Wang Haoran's research application report!"

"I think their research is completely different from yours."

Guo Weiyang took out Wang Haoran's project application report and showed it to Lin Yuanchao.

Lin Yuanchao looked through Wang Haoran's project application report with a critical eye.

The more he looked, the more surprised he became.

After all, Lin Yuanchao is an expert in computers!

He also went there to see the world.

He knew that the technology direction of Lizard Country's current microcomputers was different from that of Dragon Country.

The various application software for Xifang's microcomputers are well developed. In addition to office software, their computers also have design software and even computer games.

In comparison, Xifang's microcomputers have a wider range of application scenarios.

The main function of Dragon Country’s electronic computers today is computing.

Lin Yuanchao once thought about developing a microcomputer like Xifang's. However, he couldn't get the software right and the hardware couldn't keep up. It was extremely difficult to produce results in a short period of time!

Now, Wang Haoran is actually going to develop a microcomputer with more widespread applications like the Lizard?

Can he really do it?
Lin Yuanchao sighed in his heart. He had a hunch: that young man would definitely succeed.

Because the other party has succeeded many times. Take the chip production line of the entire industrial chain for example. He led the team to complete such a complex industrial chain in less than half a year.

Moreover, in the process of developing the chip production line, the team members led by Wang Haoran achieved dozens of major scientific research breakthroughs in succession.

At present, Longguo’s chip industry chain is being implemented in the Yangtze River Delta, and has basically been completed.

Lin Yuanchao visited the place not long ago and was impressed by the advanced production equipment.

He discovered that the chip production line led by Wang Haoran had the most advanced equipment in the world in every link.

Take the photolithography workshop for example. There are very advanced air purification devices here, which require the air purification level in the workshop to reach above level 100.

When Lin Yuanchao was visiting, the accompanying technician explained to him that one of the important reasons why the yield rate of chip production in China was too low in the past was that the air quality in the workshop was too poor, which led to the contamination of the chips.

The technician also said that Wang Haoran's team had even formulated various operating specifications for the workshop. Even the large-scale purification device used in the workshop was developed by Wang Haoran's team...

Lin Yuanchao took a deep breath, and his originally unbalanced emotions finally stabilized.

Lin Yuanchao knew that he had always been jealous of this young man.

He tried desperately to make a name for himself, in fact, he just wanted to prove that he was not as bad as Wang Haoran.

"Leader, Comrade Haoran's project is really ambitious..."

"He is trying to catch up with the most advanced computer level in Lizard Country."

"And what I find most incredible is that he actually thinks that the Chinese operating system can be easily solved."

"If he can really succeed, the pattern of the development of electronic computers in the world will be disrupted."

Lin Yuanchao said to Guo Weiyang.

Guo Weiyang smiled and said, "So, do you think Comrade Haoran's topic is necessary?"

Lin Yuanchao hesitated for a moment and said, "Oh...it is necessary."

"However, his topic is quite difficult."

"Especially the Chinese operating system, it's not easy to achieve..."

Guo Weiyang smiled and said, "Since Comrade Haoran said he wants to get this done, then I think he can definitely do it!"

Guo Weiyang trusts Wang Haoran very much.

Lin Yuanchao nodded, his face full of embarrassment: "I hope so."

"If you need me to do something, I can also share some of the tasks..."

Lin Yuanchao's words were a bit vague.

He hopes to cooperate with Wang Haoran.

However, he would never take the initiative to find Wang Haoran and ask for cooperation.

Guo Weiyang smiled and said, "According to my understanding, Comrade Haoran's research team has already completed its preliminary construction."

"Teacher Lin, you can take the initiative to ask him and see if he needs you to do something for the research group."

Lin Yuanchao waved his hands in a panic and said, "Oh, let's talk about it later."

He still couldn't bring himself to ask Wang Haoran for cooperation.

He hoped that Guo Weiyang could help Wang Haoran pass on a message.

When it came to the last big project on the chip production line, Wang Haoran took the initiative to find him and hoped that he could join.

But he refused that time.

That time, he had projects on hand and also didn't want to help the young people.

Lin Yuanchao knew very well that it would be difficult to get Wang Haoran to invite him again.

After all, there are so many people who are willing to cooperate with Wang Haoran now.

Lin Yuanchao came out of the Fourth Ministry of Machine Building. He rode his bicycle all the way while frowning and thinking.

The more he thought about it, the more he felt that if Wang Haoran's computer production line project was completed, then even if he developed a better microcomputer than DJS-050, it would not make much sense.

Because Wang Haoran's project results will completely crush him.

"Then, I think it's unlikely that I will just sit and wait for Wang Haoran to invite me to join his team."

"No, I have to take the initiative to find Wang Haoran and see if we can cooperate."

"But it would be really embarrassing if the other party rejected you."

"But if I don't go to him to see if we can work together, wouldn't that be like watching the opportunity slip away?"

"In the election for additional faculty members that just ended, I was eliminated because I didn't have solid results."

"Among the professors from our school who worked with Wang Haoran, three of them were successfully elected as academic committee members."

“So, I have to fight for it.”

"Alas! My opinion of Wang Haoran in the past was too biased. We should be more respectful of young geniuses."

Thinking of this, Lin Yuanchao gritted his teeth and rode his bike straight to Beijing Institute of Technology.

When he arrived at the gate of Beijing Institute of Technology, Lin Yuanchao looked at the glittering school name that had been replaced at the gate, and he felt very emotional.

Although this school is considered a national key school, to be honest, it was not very prominent before!

However, his recent performance has been really outstanding.

Especially in the last election of academicians, as many as 22 professors and researchers were successfully elected as academicians, ranking first in the country!

Tsinghua University only has a pitiful 8.

Our old rival Peking University has 11 of them.

Beijing Institute of Technology shines brightly!

Isn’t the reason why Beijing Institute of Technology can perform so well because of Wang Haoran?
This young man is really amazing.

Lin Yuanchao arrived at the gate, he identified himself to the guard and expressed his wish to meet Wang Haoran.

The guard said to Lin Yuanchao, "Then I'll call Comrade Haoran's office and see if he's willing to see you."

Lin Yuanchao nodded and said, "Thank you!"

Lin Yuanchao thought, it's troublesome to make a phone call and have to go through the switchboard, and it will also occupy the phone line. Usually, the guard will go over and ask in person.

He stood outside the window, watching the security guard pick up the phone and dial the number directly. Soon, the call was connected.

"Comrade Haoran, there is a professor from Tsinghua University named Lin Yuanchao who wants to visit you at the gate. Do you think it's okay?" the guard said into the microphone.

Lin Yuanchao was surprised: He called Wang Haoran’s office directly?

Is this the function of the programmable switching system that Wang Haoran previously studied?

At this time, Wang Haoran was in his office working on the research application for the refrigerator production line.

If we want to significantly improve China's industrial level within 10 years, we must accelerate research.

Wang Haoran has decided to work on several scientific research projects at the same time.

Anyway, all the scientific researchers of Beijing Institute of Technology can be mobilized. He just needs to give guidance and let other members of the team implement it!
Wang Haoran was thinking about it when the phone on his desk rang.

He reached out, grabbed the phone and put it to his ear.

The guard actually said that there was a professor of computer science at Tsinghua University named Lin Yuanchao who wanted to visit him at the gate?

After a brief thought, Wang Haoran remembered who Lin Yuanchao was.

When he was building the chip production line, he personally invited Lin Yuanchao to join the team.

However, the other party declined, saying that he had a critical scientific research project at hand.

I didn't expect that the other party would come to visit me on his own initiative.

Wang Haoran thought, this sudden visit must be related to my new topic, right?

Wang Haoran knew that Lin Yuanchao was also a master in the field of computers in Longguo and had developed domestically produced CPUs.

But, to be honest, the CPU that Lin Yuanchao made was too simple.

"Let Teacher Lin come over."

"Oh, I'll go downstairs to greet them, too."

Wang Haoran said to the guard.

Wang Haoran thought: Maybe Lin Yuan was a little arrogant in the past.

But if the other party takes the initiative to come to us, and has a good attitude and is very willing to cooperate.

Then Wang Haoran doesn't mind cooperating with Lin Yuanchao.

After all, there are many difficulties in both the software and hardware aspects of computers.

Even if he has an idea in his mind, he still needs more professional assistance.

In Beijing today, the two schools that opened computer departments relatively early are Tsinghua University and Peking University.

The Computer Science Department of Beijing Institute of Technology was established under the promotion of Wang Haoran.

The director of the Computer Science Department of Beijing Institute of Technology is a recent graduate of Tsinghua University, named Feng Xiang.

In order to develop advanced computers and their production lines, it is necessary to train a large number of professional talents.

Wang Haoran came down from the office and walked to the gate of the office building. He happened to see Lin Yuanchao riding a Phoenix bicycle towards him.

Wang Haoran had an impression of Lin Yuanchao.

Lin Yuanchao also saw Wang Haoran from a distance.

Although Lin Yuanchao has the nobleness of a scholar, he is still a relatively cheerful person.

Since you have decided to join someone and achieve some success under their leadership, you must have a good attitude.

Therefore, Lin Yuanchao smiled and greeted him from a distance: "Hello, Comrade Haoran! I am really flattered."

Wang Haoran smiled, walked over without stopping, nodded and said: "Senior, if you come to guide us, we must welcome you with open arms!"

Lin Yuanchao put his bicycle away and shook hands with Wang Haoran.

His heart, which had been hanging in the air, finally settled down a little.

He thought that Wang Haoran seemed to have a good personality and was not the kind of person who was difficult to deal with.

Lin Yuanchao followed Wang Haoran to his office.

After a few pleasantries, Lin Yuanchao took the initiative to explain his purpose: he hoped to collaborate with Wang Haoran on his new project.

After finishing speaking, Lin Yuanchao felt a little uneasy.
In fact, Wang Haoran has been secretly observing Lin Yuanchao.

He felt that the other party was reliable, so he decided to cooperate with him.
