The Red Era, the Opening University Speech

Chapter 106 Li Mu, the country needs you!

Kyoto, morning.

The spring snow has melted, and wisps of mist are hanging on the treetops along the campus roads.

After getting up and exercising on the playground for half an hour, Li Mu didn't feel tired at all except for a little sweat on his body.

He touched his head and thought to himself, "Luckily I'm not bald."

I continued running for half an hour before stopping to rest.

He returned to the tree beside the playground, took out a green military canteen from his bag, and drank it in a big gulp, feeling refreshed.

Although it was comfortable, Li Mu frowned: "It's been too long!"

It is such a waste to spend an hour or even more on exercise every day.

No matter how healthy he is, can he still become Ultraman? Besides, can Ultraman resist the giant mushroom? No.

Moreover, Ultraman’s maximum speed is only Mach 35, but future missiles can reach speeds of up to Mach 42, which is still controllable.

This is the power of technology!
"If that doesn't work, try tying some iron sand bags on your body." Li Mu finished drinking the water, rested for a while, and came up with a compromise.

Putting the kettle into his bag, he wiped his mouth and walked back to the dormitory.

……

Just as he arrived downstairs of the dormitory building, Li Mu suddenly saw a GAZ-69 military green pickup truck parked in front of the open space.

Before he could walk in, the people in the car got out.

Wang Shoujue, and a young officer he didn't know, whose rank looked like a battalion commander.

"Why are you here again?" Li Mu was a little confused.

Wasn’t this the reward for coming to France yesterday?
He looked at the young officer next to Wang Shoujue and felt something was wrong.

Sure enough, after the two approached, the first thing Wang Shoujue said was: "Li Mu, the country needs you!"

Without any nonsense, Li Mu nodded and followed the two into the car.

Wang Shoujue was rarely in a hurry to talk to him. Instead, he frowned and thought about something silently.

……

The car drove all the way to the Semiconductor Research Institute before slowly stopping.

Li Mu felt a little relieved when he saw a familiar place instead of a train station.

He was really afraid that Wang Shoujue would drag him to the Gobi Desert after hearing what he said.

The two men got out of the car, and Wang Shoujue seemed to wake up from his deep thoughts, and said as he walked:

"To make a long story short, Yuan personally issued an order for the entire institute to focus its efforts and find a way to use integrated circuits to create a tool to help with calculations."

"This mission is extremely urgent and strictly confidential. No one can leave the institute until the research is successful."

"Don't worry about the school. We will ask for leave for you, and someone will go to your home to explain and resolve your worries."

"Next, we have only one goal, to develop this computing tool as quickly as possible!"

……

Wang Shoujue spoke very quickly. While he was talking, he had already walked to the door of a meeting room.

When I opened the door, I saw that all the seats behind it were occupied except for one.

Li Mu walked towards the empty seat and sat down.

Wang Shoujue walked up to the podium in the conference room and said in a deep voice: "Comrades, the time has come for the D and the people to test us!"

This sentence was like the fuse that ignited a powder keg, causing the conference room to boil!
Li Mu looked at the national flag above the conference room, and his heart felt hot!
……

Immediately afterwards, all researchers at the Semiconductor Research Institute divided themselves into groups and launched intense discussions and research on the computing applications of chips.

One point after another was raised and debated fiercely:
"Using digital logic circuits, we can implement simple serial operations. Applying it to a chip makes it easy to do digital calculations."

"We now have dynamic random access memory, and I think we can use it in calculators."

……

Li Mu's brain was working rapidly, recording and analyzing these ideas.

At the same time, he did not forget to ask for help from Ask on the chat page: "Asker, please help me compile a set of development materials for integrated circuit calculators. My friend wants it."

"Also, the structural principles and so on, all need to be written clearly, the more detailed the better."

After receiving the message, Ask's F2A rushed into the opposing Protoss' home base, ending the two-hour bladder confrontation, and quickly replied:
"Okay, you wait for me to get off."

Not long after, Ask sent the information.

"Thank you." Li Mu thanked.

Ask: “You’re welcome.”

"Let's not talk about that for now. I need to go to the bathroom first. The Protoss I just defeated typed and taunted me, and even invited me to play another game."

"Today I will make him admit defeat with full conviction!"

After saying this, Ask didn't say anything else, probably because he went to relieve his bladder.

Li Mu sent an emoticon of "cheer up", and then turned his attention to the information.

His eyes immediately turned to the introduction of the chip:
"Are they large-scale integrated circuits made using CMOS technology?"

“It was proposed in 1963, so it should have the basis for realization.”

Li Mu quickly finished reading the chip information.

CMOS is developed based on PMOS and NMOS processes and is the mainstream process technology for future large-scale integrated circuits.

If we can take this opportunity to be the first to put forward the CMOS technology, it will undoubtedly be a good thing for the future development of semiconductors in Xiaguo.

……

Just as Li Mu frowned and thought, as the discussion was drawing to a close, Wang Shoujue called on him and said, "Li Mu, tell me, which direction should we go in for research."

Upon hearing this, everyone in the conference room immediately focused their attention on Li Mu.

Li Mu, who was already an "expert", did not shirk his responsibilities as he had done before. Instead, he stood up and said, "I think many of the professors' ideas just now are correct."

Although you are not afraid, you still need to be humble and not give people the impression that you are too arrogant.

After applying the BUFF, Li Mu continued:
"Let me sort it out first. To make a calculator, we first need an arithmetic logic unit, a general register group, a component to control data input and output, and a bus for galaxy transmission with other components."

"You may think this is complicated, but what we want to do is not to copy the functions of a hand-cranked calculator to an integrated circuit calculator."

"Instead, we need to develop more functions, such as operations on exponentiation, opening, exponentiation, logarithm, trigonometric functions, etc."

……

Li Mu first instilled some calculator concepts into everyone present.

After all, no matter what semiconductor process technology it is, it is relatively blank in China now. It is not enough for him to understand it alone, everyone must understand it.

The people in the audience were listening to the story with either frowning faces, or looking thoughtful, or having sudden enlightenment.

But they did one thing in common, which was to use pens to quickly record what Li Mu said.

When Li Mu finished speaking, there was warm applause from the audience:

"Well said, with a novel perspective and a penetrating analysis of the nature of calculators."

"My mind was a mess just now, but after listening to his analysis, my thoughts became more clear."

"You are indeed a genius. Your ideas are always ahead of ours."

……

Faced with the applause and praise, Li Mu turned around and bowed deeply.

When the applause died down, Wang Shoujue looked at his watch and said, "Well, it's already 12 o'clock today. Let's take a break first and we will continue the discussion tomorrow."

"Accommodation has been arranged for everyone. Someone will lead the professors there later."

After saying that, he waved to Li Mu again and walked out of the meeting room.

After coming out, Wang Shoujue hesitated and said, "Our school has limited accommodation, how about you squeeze in with me?" "I'll obey your arrangement." Li Mu agreed without hesitation.

Wang Shoujue couldn’t see the chat page, so he was careful not to be exposed.

The next day.

Waking up on time, Li Mu left Wang Shoujue's residence and went to the small playground to start exercising.

Although it was his first time living in a semiconductor research institute, he was not unfamiliar with this place at all.

After running, I went to the cafeteria to eat.

Before he opened his mouth, the lady serving the food understood: "I know, I know. Seven servings of rice, four meat dishes, and two non-vegetarian dishes."

Hearing this amount of food, people in the cafeteria looked at him sideways.

But when they realized it was Li Mu, they looked away.

You are called a big eater, so eating just this little bit is nothing.

……

Holding the meal, Li Mu found an empty seat and sat down. He ate while writing and drawing on the side.

This is an indispensable disguise to reasonably bring out the various technological processes of the calculator.

Just when Li Mu was enjoying his meal, a voice sounded behind him: "Li Mu, what are you thinking about? You are so absorbed in your thoughts."

Hearing this voice, he stopped his fingers and smiled, "I was just thinking about the calculator."

"Ha, you are so focused that you even forgot to eat. How about it? Do you have any ideas? Tell us and we can discuss them together." Wu Xi sat down with a smile and sighed:

"Your words yesterday benefited many senior researchers and professors a lot!"

"It's just the basics, and it hasn't touched the core." Li Mu waved his hand.

Although he had the information in hand yesterday, he would not dare to tell the truth if he did not understand it well, otherwise he would not be able to explain it clearly.

"Hey, this is a relatively unfamiliar application field. It's normal that you have no idea for a while." Wu Xi thought he was under pressure and comforted him.

"Not really." Li Mu smiled and said, "I actually have some ideas, but they still need to be verified."

"What?" The bun in Wu Xi's hand fell onto the plate.

He didn't even bother to eat breakfast. He grabbed Li Mu's hand and said, "Let's go to the meeting room now!"

……

In the conference room.

Several halogen lamps on the roof emit orange light.

At this time, there were already quite a few people inside.

Wang Shoujue got up a little later than Li Mu, but he didn't need to exercise, so he came to the meeting room after breakfast.

He held yesterday's notes in one hand and kept calculating on the manuscript paper with the other, his brows furrowed into a big "川" shape.

He raised his head slightly when he heard the sound of someone running in breathlessly.

Wu Xi pushed Li Mu forward and said, "Director Wang, Li Mu said he has a new idea."

Hearing this, seven or eight people in the conference room put down their research and looked at him expectantly.

Wang Shoujue couldn't wait any longer and said, "Tell us about it quickly."

Facing everyone's gaze, Li Mu hesitated for a moment before saying, "I have made some improvements to our original practical chip."

"First, in terms of process, we create the same inversion region on the P-type silicon substrate and N-type silicon substrate, the basic structure of the transistor."

"Before implantation, high-energy, high-dose ion implantation is used to adjust the threshold voltage of the transistor..."

……

The process principles of COMS technology are quite complicated. Although it has been simplified again and again, it still took Li Mu nearly half an hour to finish explaining it.

When he finished reading the last word, he just breathed a sigh of relief, but when he looked up, he was shocked.

I don't know when the conference room was already full of people.

Warm applause broke out the moment he raised his head:

"It is a blessing for the country to have Li Mu!"

"We haven't even figured it out yet, but he has already figured out the key technology. I really don't know how to describe his talent!"

“Haha, maybe this is the difference between ordinary people like us and Tesla!”

……

When the applause died down, Wang Shoujue sighed:
"He not only solved the problem of calculators, but also solved part of the problems of integrated circuit computers in the future!"

Only then did everyone realize that chips made with CMOS technology can be used not only in calculators, but also in computers.

Then there was another round of thunderous applause.

Soon after, with the basic principles of CMOS technology, the Semiconductor Research Institute quickly took action.

After Wang Shoujue assigned the tasks, he looked at Li Mu and asked:
"I want to set up a special research group to study CMOS technology. Are you interested in taking on this responsibility?"

What he meant was obviously not to let Li Mu just serve as an assistant as before.

After all, Li Mu is now an "expert".

"No, no, I'm okay with the theory, but I can't take the lead." Li Mu shook his head quickly. It was difficult for him to understand it, let alone lead a team to do it.

Instead of torturing yourself painfully, it is better to let the big guys solve it.

"But now, apart from you, who else in the Semiconductor Research Institute can take on this important task?" Wang Shoujue asked back.

Li Mu also felt it was a bit prickly.

He frowned, then looked around as if he suddenly realized something and asked, "Director Wang, where is Professor Huang? Isn't he participating in this emergency mission?"

If we talk about the big names in the semiconductor industry, Huang Xinhua must be one of them.

"Professor Huang, it seems he is out for exchange and study, and was delayed on the road. However, after receiving the order, he should be here in the next two days." Wang Shoujue said.

He vaguely guessed what Li Mu was thinking.

As expected, Li Mu immediately said, "Then wait for two days and let Professor Huang lead the team to do the research. I can then perfect the theory."

"Besides, having a CMOS alone is not enough. The calculator is an urgent task assigned by the higher-ups. I think we should focus on this first."

Wang Shoujue nodded when he heard this, and thought that it was indeed true.

The calculator is related to the research in the northwest. Although his superiors did not say it explicitly, how could he not guess it?

He nodded slightly and said, "Okay, then step back a little."

……

Two days later.

As computer experiments continued to move forward.

Huang Xinhua rushed back to the Semiconductor Research Institute exhausted.

As soon as he entered the institute, he went to the meeting room without taking a rest.

Li Mu on the stage talked freely:

"In a matrix keyboard, after setting all row lines to low level, the status of the column lines is detected. As long as one column is low, it means that a key on the matrix keyboard is pressed."

"Delaying keypresses can be accomplished by adding a bistable trigger or a monostable trigger to the key output to form a de-bouncing circuit."

……

After Li Mu finished speaking, applause broke out from the audience.

Afterwards, Wang Shoujue walked out from the side and quickly assigned research tasks according to Li Mu's ideas.
