The Red Era, the Opening University Speech

Chapter 107 sets another precedent!
Huang Xinhua came in from outside when he saw this, and said with a smile as he walked towards Li Mu:
"Your speech just now was very good. You are becoming more and more like an 'expert'!"

"Thank you for the compliment." Li Mu turned his head and saw that it was Huang Xinhua. He smiled but did not show any more modesty.

The rapid improvement in his status and position meant that he was destined to be different from before, otherwise people might think he was hypocritical.

While the two were talking, Wang Shoujue finished his arrangements and came over. He greeted Huang Xinhua first, then said:

"Professor Huang, someone should have explained this emergency mission to you on the way here, but you probably don't know the specific content of the mission yet..."

He briefly recounted the calculator mission and the research progress of the past two days.

When he heard Li Mu propose the CMOS process, even though he was mentally prepared, he was still shocked.

Huang Xinhua sighed:

"This idea is really amazing. CMOS technology plays an extremely important role in the development of integrated circuits. Who would have thought that it was invented during the development of calculators?"

"Professor Huang, you are not entirely right. CMOS technology is important, but calculators are not necessarily that bad. Sometimes one achievement is just to pave the way for another." Wang Shoujue said meaningfully.

Hearing this, Huang Xinhua was stunned for a moment, then reacted.

The biggest function of a calculator is calculation. In the field of scientific research, no research can bypass this issue.

But there was only one person who could get the superiors to issue an urgent task and mobilize the entire Semiconductor Research Institute and other experts and professors in the semiconductor industry to devote their full attention to the research of calculators.

Listening to the conversation between the two, Li Mu was also thoughtful.

He had never really thought about why his superiors suddenly gave the Semiconductor Research Institute the task of developing a calculator.

Now that I think about it, there is probably only one possibility:
"Big mushroom!"

"Director Wang..." The moment Li Mu realized it, he couldn't help but want to confirm with Wang Shoujue.

That’s a big mushroom!
Compared with those scientists who have left their mark in history books, his achievements in semiconductors can only be regarded as a tiny ripple in the long river of history.

"Hehe." Wang Shoujue looked at the question in Li Mu's eyes, just smiled and did not give a direct answer.

Huang Xinhua also smiled but said nothing.

But this further confirmed Li Mu's guess.

If it wasn't a top-secret study like Big Mushroom's, it would be impossible not to tell him anything.
Wang Shoujue coughed lightly and continued, "Well, since Professor Huang is here, we can put our research on CMOS technology on the agenda."

"You will also be the leader of this research team!"

Hearing this, Huang Xinhua was a little surprised: "Director Wang, shouldn't Li Mu be the leader? How can I do it?"

"Before, he was just a student and his status was not appropriate, but now he has an expert allowance and is no less than us in terms of academics and status."

"He should be the one leading the CMOS process this time!"

Faced with the doubts, Wang Shoujue did not say anything, but just looked at Li Mu.

He won't take the blame.

"Professor Huang, this is my idea." Li Mu took over the conversation, "Please listen to me first. I have two considerations for letting you be the leader."

"First, the entire institute is now focusing on completing the urgent tasks assigned by the superiors, and I am needed to contribute in this regard."

"Second, I am still in school. Researching CMOS technology is not a small project and requires a lot of time and energy."

"You don't want me to fail the course and not graduate because of skipping classes, do you?"

These two reasons left Huang Xinhua speechless.

He could only agree first.

……

With the joining of Huang Xinhua, the research on CMOS process officially began.

However, CMOS is essentially used to develop computers, and the current research focus of the entire Semiconductor Research Institute is still calculators.

……

Ten days later.

After basically solving the problems of the arithmetic unit, controller, memory, keyboard, etc., the next thing to discuss is the display problem:
"I think we can just use the hand-cranked calculator method and add a conversion method to display the result."

"Hand-crank calculators are mechanically driven, which is completely different from the chip calculators we are studying. We should find a new, simpler and clearer way."

……

The atmosphere in the conference room became noticeably more relaxed and cheerful.

There are many veteran researchers and professors who have participated in emergency missions before, and they originally thought that this would be an arduous scientific research battle.

But in just twelve days, a complete theoretical framework was established and experiments were started, which amazed them all.

Thinking of this, they all turned their heads and looked towards the back of the meeting room: "Li Mu, what do you think?"

Such inquiries after discussion have almost become their routine.

Mainly, I can really hear things.

Li Mu slowly stood up, walked quickly to the stage, glanced at the expectant crowd, and said: "I think we can make a light-emitting diode based on the diode."

"Light emitting diode, what is that new thing?" Wang Shoujue on the side couldn't help but ask.

Li Mu said: "In fact, the principle is very simple, that is, when electrons and holes recombine in a diode, they can radiate visible light."

"Using this visible light, we can create a display of text or numbers."

"Assume that each light-emitting diode is placed at the intersection of a row line and a column line. When a corresponding row is set to 1 and a corresponding column is set to 0, the corresponding diode will light up."

……

As Li Mu spoke, he drew a sketch on the blackboard.

Light emitting diode is actually LED.

But unlike later LED display screens that use hundreds of thousands of light-emitting diodes, a calculator only needs 8X8, a total of 64 light-emitting diodes to be made.

This is completely achievable with current technical conditions.

After he finished speaking, Wang Shoujue was the first to applaud: "He is indeed the Edison + Tesla-like genius that President Guo praised. He is good at research and inventions!"

The researchers and professors in the audience also applauded and praised generously:

"This application of diodes is probably the first in the world!"

"Yes, it has set a new precedent!"

……

The display problem was successfully solved.

The meeting ended quickly. Under the pressure of the urgent task, everyone rushed to study.

Now that the technical theoretical framework of the calculator has been fully established, the next step is to continue experimenting.

After arranging the tasks, Wang Shoujue looked at Li Mu again and said, "Do you want to go to Professor Huang to continue studying CMOS technology?"

Huang Xinhua just happened to walk over and looked expectant when he heard this. He also wanted to talk about this.

Although Li Mu would occasionally provide guidance, the effect would definitely not be as good as if he participated in person.

"I don't think that's necessary. Professor Huang will lead the way, and it will be enough for me to go there occasionally." Li Mu thought for a while and said, "And I plan to do some more in-depth exploration on light-emitting diodes."

After he finished speaking, Huang Xinhua showed a strange look in his eyes and asked:

"Light-emitting diodes are just displays on calculators. They are not as important as CMOS technology. Why did you think of studying this?"

Li Mu said: "Integrating only 64 LEDs is of course nothing, but what if we can integrate thousands, tens of thousands, or even hundreds of thousands?"

"Since it can form numbers and words, it can also form images."

"However, unlike movies, which simply play recorded images, its images can be controlled and changed by us."

After he finished speaking, Wang Shoujue and Huang Xinhua couldn't help but frown.

"But what's the use of simple image display?" Wang Shoujue asked.

Just forming control images doesn't seem to be of much help to their research.

"Of course it is useful!" Li Mu affirmed: "For example, when computers are used for missile calculations, it was previously necessary to draw a 'shooting chart' and then determine the muzzle angle after looking up the table to accurately hit the target." "But with the image display, we can not only simulate the entire process, but also simplify the 'shooting chart' into the most intuitive muzzle angle."

"In this case, the soldiers just need to fight according to the parameters."

After listening to this, Wang Shoujue said thoughtfully: "So its function is to simplify the process?"

"But if it's just a simple simplification of the process, the value may not be very high." Huang Xinhua still wanted Li Mu to participate in the more important tobacco and alcohol.

"Of course it's not as simple as simplifying the process." Li Mu thought for a moment and said:

"Its greatest use is that it forms a human-computer interaction window between humans and computers."

"Through this window, we can give instructions to the computer, view stored files on the computer at any time, and perform multitasking..."

"So that's how it is. That's indeed very important!" Wang Shoujue suddenly reacted when he heard this.

The current computer job sequence is to record the work into a tape drive in an offline manner, and then configure a supervisory program in the system to complete the work in batches.

This method obviously cannot fully utilize the computing power advantages of integrated circuit computers.

"In the long run, the role of this light-emitting diode is no less than that of CMOS technology!" Huang Xinhua also agreed.

Wang Shoujue continued, "Then you can just be the instructor. When you are free, you can study light-emitting diodes."

Li Mu nodded happily.

……

After solving the theoretical problems, Li Mu had some free time.

Most of the remaining research are minor problems that can be solved by the people in the Semiconductor Research Institute themselves.

His daily task was to go to Huang Xinhua's place. If there was something to do, he would stay there. If there was nothing to do, he would return to his residence and take out manuscript paper to study the chip problems of integrated circuit computers.

Occasionally chatting and gossiping with Ask is one of the few entertainment and leisure activities.

……

Time flies and another seven days have passed.

Under the urgent task from above, all researchers worked overtime and finally developed the first chip computer.

"Success, success!" The cheers of the researcher came from the laboratory and fell into Li Mu's ears.

He took a few quick steps and walked into the laboratory.

There was cheering in the laboratory.

In front of the operating table, a calculator with a slightly sloppy appearance was placed in the center and was being debugged by Wang Shoujue, Huang Xinhua and others.

Seeing him coming, Wang Shoujue hurriedly said, "Li Mu, come over here and try!"

This sound immediately silenced the researchers who were originally cheering, and their eyes showed tension.

"Okay, let me take a look." Li Mu was also a little excited. He took a few steps forward and looked at the calculator.

Its size is completely different from the light and compact ones of later generations, and it is as big as a basketball.

But appearance is not important, function is the key.

Li Mu stood in front of the operating table and started with the simplest 1+1.

=2.

The answer is quickly displayed on the dot matrix LED display.

A little more complicated, 5323X8924.

=475854452.

Power, open, exponent, logarithm... after the numbers are input one by one, the answers are output quickly.

The entire calculation process does not exceed 1 second.

This speed has left hand-cranked calculators far behind.

"No problem at all!" Li Mu made his judgment.

Everyone in the laboratory was excited after receiving his affirmation.

Wang Shoujue immediately said loudly: "Thank you all for your hard work. Our efforts over the past few days have paid off."

"Everyone, go and rest now, I will report this news to the director."

"Let's celebrate together tomorrow!"

After saying that, he looked at Li Mu and said, "Let's go find Director Wu together!"

……

After Wang Shoujue and Li Mu reported, the news of the successful development of the calculator was quickly sent to Nanyuan by Guo Mo, the president of the Chinese Academy of Sciences.

The superior leader couldn't help but laugh and said, "This Li Mu really didn't disappoint me."

"With this calculator, the research progress of the giant mushroom can be accelerated a lot!"

He was really happy.

Even if it is an urgent task, in theory it would take at least half a year of research to produce useful results.

But who would have thought that the Semiconductor Research Institute completed the development of the chip calculator in less than a month.

The secretary quickly took the order and left.

The superior leader couldn't help but think of a question: "What kind of reward should be given to this little guy Li Mu?"

There is also the Semiconductor Research Institute. I have been there twice, so going again would be too often.

Thinking of this, the superior leader walked out of the house and decided to find Leader Yuan to discuss the matter and tell him the good news.

……

Seven days later.

Northwest, a base.

Trucks, braving the wind and sand, crossed the vast Gobi Desert and drove into the gate of the base.

The director of the research institute had been waiting here early, and the moment he saw the truck, his eyes lit up with joy.

"Here they come, here they come." A middle-aged researcher in his forties next to him looked excited.

After saying that, he quickly ran back and called the researchers in the base to come out.

Soon, the truck stopped and boxes of machines were unloaded from the truck.

The base researchers lined up to receive their calculators and were very curious about this brand new machine.

When the person in charge saw the finished calculator and the instruction manual, he was shocked and surprised.

He originally thought he had just made a calculator to replace the abacus.

But after looking at the instructions, I found that the functions of this chip calculator can not only replace the abacus, but can even replace the traditional hand-cranked calculator.

Moreover, this improvement is not just a little bit. Not only has the number of calculation bits increased, but the calculation time has also been shortened to less than 1 second.

In this way, the big mushroom research will save a lot of time in calculations.

"Comrades!" The person in charge held up a calculator and said, "Everyone should get familiar with the use of calculators as soon as possible. Don't let down the country's support and expectations of us!"

"We must get the big mushroom out as soon as possible and give our motherland a satisfactory answer!"

After a brief encouragement, without much delay, the researchers at the base quickly returned to the laboratory to continue their computing tasks.
