The ups and downs of life in the Siheyuan

Li Yuan knew Huang Yan too well. As long as it was something novel, she would be busy developing it herself without any urging.

Now that the CPU is not fast, the bus matrix can connect several CPUs and RAM together.

Hao Wei's distributed algorithm has been successfully developed. By then, using current technology, computing power will be greatly improved.

As technology accumulates and servers are developed, it becomes possible to build large computer arrays.

Now Li Yuan is more like a conductor and strategist, constantly giving technical guidance, hoping that they can spontaneously carry out technological upgrades.

In this way, the team can be cultivated and trained. In the future, these people will be the seeds, and there will be greater possibilities in the future.

In the days that followed, Hao Wei's team rarely stayed in the laboratory and fully participated in the construction of the military Internet.

Li Yuan is currently more concerned about the work of the simulation technology team.

They were selected from the team of Senior Brother Gong and Senior Sister Huang Yan to serve as the team leader and deputy team leader respectively. The team leader is a graduate of the 60s named Shao Yong.

They are currently working hard on analog devices and are mainly responsible for the design, optimization and improvement of power supplies, power devices, operational amplifiers, ADCs, DACs and other components.

The main customer is the military, and the research content is mainly automatic control.

Representative Tiantong found Li Yuan again.

"Old Li, the current circuit board is still too big. The National Research Institute has obtained an American air-to-air missile from the south and is working on it.

The main bottlenecks at present are the flight control system and the engine.

They have been working on it for more than a year, and the engine is making good progress, but the flight control system has been a problem.

Taking into account your outstanding performance in the Turbo-6 modification, the chief hopes that you will also help design a low-power control system."

After finishing speaking, he took out a document and handed it to Li Yuan.

After roughly browsing it, Li Yuan felt confident.

Although the model of the missile is not known, only the guidance and control module information is available, but it can be seen that America's current missile technology is very advanced.

The guidance and control cabin is equipped with gyroscopes, accelerometers, antennas and receivers, computing devices, servos, batteries and high-voltage energy sources.

A circuit made of soldered semiconductor components selected for use in computing devices.

This aspect is really the advantage of the laboratory.

"No problem, how long will it take?"

"The sooner the better!"

Li Yuan glanced at him angrily, "There must be a number."

Representative Tong didn’t have any embarrassment, “Is it feasible in half a year?”

"How much does it cost?"

"Why is it funding again? We are helping you build a new laboratory, and we will be a family from now on."

"Then is later, now is now"

"You are just stubborn. Okay, I'll go back and ask. There won't be any problem in half a year."

"It's difficult, but we can find ways to overcome it."

"That's enough. I'll go back and ask you for funds first, and then you can get started."

Representative Tong left, and Li Yuan fell into deep thought.

He was considering whether to hand over this project to others, but after looking through everyone's projects, he found that they were all at critical moments.

In the end, I had no choice but to do it myself.

The current Pangu CPU itself is a streamlined system, and its power consumption is much smaller than that of later generations of X86.

So for now, we only need to consider how to design a more streamlined microcontroller, similar to the ARM series of later generations.

After many calculations, I decided to add internal FLASH and RAM on the basis of Pangu CPU, add a serial port to the periphery, and integrate a 16-bit timer internally.

Compared with later generations, although external resources are much poorer, they can basically meet the application needs in the next ten or twenty years.

The external package adopts the same LQFP144 compact design as Pangu.

The next work is basically the workload.

The final parameters are:

32-bit Pangu computing unit;

8-bit external data bus;

16KB internal RAM;

8KB internal FLASH;

2-way UART full-duplex serial port;

2-way CAN interface;

3-way 16-bit timer.

The others are mature designs, and the only new design is the CAN bus.

Time has entered April, and most of the designs have been completed for the microprocessor temporarily named Pangu series by Li Yuan.

I have urged the construction progress of the new laboratory several times, and today I received bad news.

The construction of the new laboratory was stopped by superiors on the grounds that the project investment should be re-evaluated to prevent duplication of construction.

Hearing the news, Li Yuan felt uneasy. He did not expect that the process of history would be so fast.

"Old Tong, you have heard some rumors about the importance of the laboratory, and you should know it best.

If we cannot move out of here as soon as possible, we will not be able to bear any danger."

After Li Yuan finished speaking, Representative Tong lowered his head and said nothing.

"What do you mean, you should just squeak!"

"I didn't want to tell you that General Tan was transferred to the southwest two months ago to attend a study class. The new chief began to reorganize the base as soon as he arrived.

I have just finished studying, and I rushed to you as soon as I came out.

If you have any way, find it as soon as possible."

After Representative Tong finished speaking, his eyes were filled with confusion.

Li Yuan was just stunned for a while, then got up and left.

As soon as I walked out of the small conference room, I met Leader Xu who came in a hurry.

Seeing his expression, Li Yuan couldn't help but smile bitterly. He knew that what was supposed to come would still come.

He let Leader Xu into the small meeting and closed the door behind him.

"Xiao Li, I have to go south to study in another week, and I can't take care of you here."

"What to do here?"

"I suggest that this laboratory be temporarily closed. The person who takes over my job is a lunatic. He only knows how to shout slogans and does not care about scientific research at all. He wants to send all scientific researchers to the suburbs to work."

"Isn't there anyone from above to take care of it?"

"There are some things I can't tell you clearly. How to retain the talents here is the most important. I can transfer some people to the 700 factory, but I can't do anything about the others."

"Gong Liming, Huang Yan, Xiao Zhiwu, Zhang Yang, Guo Jun, Hao Wei, Ai Xing, Bi Yandong, Wang Kai and Shao Yong must be protected," Li Yuan said with a firm expression.

"As for you, you have to know that you are more important than others," Leader Xu said anxiously, and Representative Tong nodded.

Li Yuan did not speak and stepped back. When Representative Tong was confused, he appeared beside Representative Tong and put a knife on his neck.

"Xiao Li!" Leader Xu shouted.

Li Yuan let go of the frightened representative Tong and walked to the conference table. He patted it lightly with his right hand. There was not much movement, and the table immediately shattered.

Before they could ask questions, Li Yuan took out an ID and handed it to Leader Xu.

Leader Xu only glanced at it and handed it to Representative Tong. He knew Li Yuan's other identity.

"Your skills are good, but it's too risky for you to stay," Leader Xu said.

After reading the certificate, Representative Tong nodded and said, "You must know your importance."

"In order to keep this place, I have to stay. With another identity, there should be no problem with safety."

"It's still too risky." Leader Xu found it difficult to accept his decision.

“There are so many people here, and once I leave, they will inevitably do something that we cannot accept.

Moreover, I am also the director of the maintenance shop. From now on, they will all be employees of the maintenance shop and power supply station.

Our two factories together are proletarian, and there is nothing we can do about others.”

"Let me think about this. I'll take away these people you reported first."
