The Immortal Warrior: From Reverse Engineering to Forging Swords for the Country

Chapter 13 Mastering ARM Architecture Patterns
  In the process of Zhang Zhipeng studying the 286CPU in his hand, the experience progress bar of CPU design skills was also increasing rapidly.

Forty-three percent, forty-four percent... ninety-seven percent, ninety-eight percent... one hundred percent!
  [Congratulations to the host for acquiring primary CPU design skills! 】

[You have mastered the skills and experience of designing CPU with ×86 architecture! 】

[Now, please try to design your own CPU using the x86 architecture. During the design process, your CPU design skills will continue to improve! 】

Zhang Zhipeng snapped his fingers, with a look of joy on his face.

Now, he found that he had a very deep understanding of CPU design.

There are a total of 4 modes in the mainstream design architecture of CPU.

The earliest one to appear was Intel's ×86 architecture, a 1978-bit microprocessor that appeared in 16. Its emergence ushered in a new era of computer development and made microcomputers popular.

Zhang Zhipeng immediately began to design his own processor based on the ×86 architecture.

As soon as he started, he discovered that this was really a very complicated project.

Even if he already has basic CPU design skills, this cannot be achieved overnight.

Zhang Zhipeng spent the entire morning designing his first CPU.

He was so involved that he didn't even eat after dinner time.

By about 1:40 in the afternoon, he was almost finished.

And throughout the process of designing his first CPU based on the ×86 architecture, his experience value was also increasing.

[Congratulations to the host, your CPU design skills have been upgraded to intermediate level! 】

[Congratulations to the host! The system unlocks the progress bar for improving the design skills of ARM architecture microprocessors for you! Please keep up the good work! 】

ARM architecture, which is another independent CPU design architecture model. It was officially formed in 1985, using a reduced instruction set and using a 3-micron chip. In its previous life, this architectural model was very widely used in embedded system design products, yes! Later, when mobile phones began to develop rapidly and become popular, most mobile phone manufacturers adopted the ARM architecture.

Therefore, this ARM architecture is really important. Zhang Zhipeng stretched himself. Only then did he feel his stomach growling.

I looked at my watch and saw that it was almost 2 p.m.

At this point, there must be no food in the restaurant.

He got up and grabbed a glass of hot water and drank it in one gulp.

The hunger still cannot be suppressed.

Zhang Zhipeng hesitated whether to go to the street to buy something to eat.

But he felt that it was a waste of time!

Because the design drawing of the first CPU based on the ×86 architecture he designed is now just a little bit closer to completion.

He thought that if it didn't work, he would just finish the work at hand and then go eat.

But at this time, my stomach was rumbling and very uncomfortable.

Just when he was struggling, the door to his office was pushed open and Zheng Jingzhi walked in.

"Zhipeng, didn't you go out to eat at noon?" Zheng Jingzhi held an aluminum lunch box in his hand.

Zhang Zhipeng could already smell the aroma of the food.

It smells so good!

My mouth is almost watering.

Zhang Zhipeng thought to himself, Teacher Zheng is not here to deliver food to me, right?

No, that's impossible. I'd better not be too pretentious.

Zhang Zhipeng said with a smile: "After I got busy, I forgot about eating."

"I just said I was going to go down and have something to eat."

Zheng Jingzhi put the lunch box in his hand on his table and glanced at the scattered things on the table. He couldn't figure out what Zhang Zhipeng was busy with.

The table was filled with various drawing tools and a computer motherboard that had been torn into pieces. It looked really messy.

There are drawings on the table. It looks like a circuit diagram?

Zheng Jingzhi said: "People are like iron rice and steel. If you don't eat one meal, you will be hungry."

"Be sure to eat in time!"       "I bought you a lunch box from the street."

Zhang Zhipeng was overjoyed and moved, and he quickly said thanks: "Thank you, teacher."

Zheng Jingzhi waved his hand to say you're welcome, but finally couldn't help but ask: "What are you drawing?"

Zhang Zhipeng said: "I'm not busy with anything, I'm just trying to design the CPU."

"Our avionics system needs the support of the CPU to be more intelligent and easy to control."

"I want to design a CPU that can be used in aircraft avionics systems to centrally process information transmitted from sensors in various subsystems, thereby greatly simplifying the control and stability of the aircraft."

Zheng Jingzhi's eyes widened: What Zhang Zhipeng wants to do is exactly what the current domestic third-generation fighter jets are required to achieve!

In fact, Yingjiang's fighter planes have already achieved this goal.

China once wanted to introduce the other party's entire avionics system technology through imports.

However, after many twists and turns, it ultimately failed.

How could the West allow its imaginary opponent to obtain this killer weapon?
  Our country has no choice but to rely on our own efforts!
  Zheng Jingzhi did not expect that Zhang Zhipeng would take care of this matter himself.

He took a breath and forced himself to suppress his inner excitement, thinking, this time, maybe I really picked up a treasure.

He smiled and said: "Eat quickly! You can continue to work only when you are full."

Zhang Zhipeng smiled and nodded and said, "Okay! Thank you teacher for your concern!"

Zheng Jingzhi patted Zhang Zhipeng on the shoulder and said: "My knowledge reserve is already outdated, and I can't get involved in the work you want to do! However, if you need anything, just tell me! I will try my best to help you. Settle it!"

Zhang Zhipeng opened the lunch box and saw braised pork, fried fish cubes and vegetables inside.

He swallowed his saliva and said with a smile: "Teacher, you are too humble. You are experienced and knowledgeable. You are one of the top authorities in the entire avionics field. I will still ask for your advice in the future."

Zheng Jingzhi smiled and said, "Okay, stop flattering and have a good meal. I'll leave first."

Zheng Jingzhi returned to his office. As soon as he sat down, he received a call from Qian Yizhou, secretary of principal Dong Haoming.

"Teacher Zheng, is there something wrong with the application you made?"

"That Zhang Zhipeng is just a worker. If you suddenly mentioned the salary level of a researcher to him, I'm afraid it's very inconsistent with the regulations, right?"

"Doing this will cause great dissatisfaction among the entire school staff."

Researcher is equivalent to a senior professional title and is on the same level as a professor. It's definitely a bit outrageous to go from being an ordinary school worker to enjoying the status of a professor.

Therefore, it is normal for the principal's secretary to have this question.

Zheng Jingzhi explained patiently: "Xiao Qian, Zhang Zhipeng is not an ordinary person. He is a top programming expert that we urgently need."

"It's not easy to find such a person across the country."

"Our employment mechanism cannot be too rigid, right?"

"For such outstanding talents, we should give him the best treatment so that he can work with peace of mind and help the school achieve results as soon as possible."

Qian Yizhou smiled and said, "I don't believe what you said."

"Not to mention the whole country, our school's electronic engineering department probably has quite a few programming experts, right?"

"Also, the rules of the school should not be broken casually. All kinds of unfair things can easily happen. Don't make it worse if the time comes. You are a leading authority in the academic world. You should know not to suffer from injustice rather than from being few. principle."

When Zheng Jingzhi heard this, he immediately became very angry: "What do you mean? Do you suspect that I am nepotistic?"

"I am also doing this to get the current topic at hand to open up as soon as possible."

"What time is it now? It's urgent!"

"Our third-generation aircraft has been waiting for many years, and it has not yet flown into the sky! Is it easy for me to find a talent after all my hard work?"

“Aren’t we doing everything for the advancement and development of national defense?”

"Why are you talking to me about this?"

"Xiaoqian, just tell me, whose opinion is this? Is it yours or the principal's?"

"I'm going to see the principal right away and ask him to give me an explanation!"
