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

Chapter 125 CMOS and CCD Mode

Zhang Zhipeng smiled and patted her back and said, "Thank you for your hard work."

"However, I still want to criticize you a few words. Minmin, your working methods are not quite right."

"You don't have to do everything personally and do the kind of management that sticks to the end."

"If you do that, you will feel very tired, and your subordinates will also feel very tired."

"Learn to let go!"

“Let the management system do its job.”

“It is much more effective to use systems to manage employees than to manage them personally in every detail.”

"A smart boss values ​​governance by doing nothing. I don't look at your work process, I only assess your final results! That's great!"

Zhao Min shook his head and said: "I have actually been trying to be a bystander-style manager."

"However, many times, when I see working methods and behaviors that I think are bad, I just can't help but want to take care of them. Alas! Maybe it's because of my personality! I'm a bit pursuing perfection..."

"I will change it."

Zhang Zhipeng said with a smile: "I was wondering if we have been unable to have children because we are both too busy and under too much pressure?"

"How about I give you a year's leave and you can be my life secretary from now on?"

Zhao Min smiled and said: "Really or not? I am willing to be your life secretary! But if you are busy with other things all day long, who will manage the company? If the company does not have a responsible manager, it will probably Is there something going on?"

"Also, I feel that my inability to get pregnant may not be due to stress, but may also be due to my body not being well-conditioned."

"I went to the hospital for a physical check-up and everything is fine."

"Perhaps, with a little more conditioning, you can get pregnant?"

"In addition, I asked for a prescription from an old Chinese medicine doctor. From now on, if you have been in Chang'an during this period, try drinking it for a while. How about it?"

Her words were a bit reserved.

But Zhang Zhipeng could hear what she meant.

Zhang Zhipeng's heart skipped a beat: If there is no problem with Zhao Min, then it's not because I have any problem, right?

However, he immediately rejected the idea.

Because, although he has been a little busy in the past two years or so.

However, I have no problem sleeping and eating, and my body is quite healthy.

There are no bad habits, and there is no relevant medical history in the family.

You shouldn't have a problem with yourself.

With this thought in mind, he smiled and said, "Okay, it won't be a problem to adjust it."

After Zhang Zhipeng returned to Chang'an, he naturally had to be busy for a while to deal with the problem of squeeze from companies on both sides.

However, overall, there are no major problems with either Loongson or Huaxing.

This is mainly due to the fact that Zhang Zhipeng has established a complete and reasonable system in both companies.

Moreover, the people employed are also very capable. In addition, the company is booming and the employees have a strong sense of belonging.

In this way, company management only needs to follow the rules, and then it can move forward steadily.

But even so, as the boss, he still needs to show his face, give a speech, do research and so on.

The most important thing is that he must hold Huaxing's financial and personnel rights in his hands.

He should be familiar with every talent, understand them, put them in the right position and let them contribute to the company.

This also takes some time.

While handling company affairs, he also found several partners to help him conduct research.

Two days later, Zhang Zhipeng began to retreat.

He has to start working as quickly as possible and strive to produce a digital high-definition camera (video camera) as soon as possible.

Therefore, Zhang Zhipeng locked himself in a room for many days to check information and design CMOS chips on process design software.

Hard work paid off. After nearly a week of hard study, he finally upgraded his CMOS chip process design skills to an advanced level.

He finally came up with a CMOS chip design through careful consideration.

Looking at the first CMOS chip he designed, Zhang Zhipeng was a little ecstatic. By the way, this is not the category of reverse engineering...

This is already an innovation from scratch to 1!

In this process, he has no object to reverse engineer.

He needs to figure it out and do his own research.

Go look up some unclear theoretical knowledge and papers yourself.

These papers are really hard to find!

After all, there are no Internet search tools these days.

If he wants to find information, he must go to the library.

The library may not necessarily have relevant information.

He also has to ask someone to find relevant papers.

But, no matter what, his CMOS chip was finally designed.

This CMOS chip was very important in smartphones in previous lives. Without it, would a smartphone want to achieve high-definition photography? There are no doors.

In fact, there are two technical routes for digital cameras.

One is a CMOS camera.

Another type is the CCD camera.

CMOS stands for "Complementary Metal Oxide Semiconductor", which is essentially a large-scale integrated circuit chip.

CMOS cameras capture images using a CMOS sensor, reading pixel data in a progressive scan manner.

It has fast reading speed and low power consumption. It can use semiconductor manufacturing processes and can be integrated with other circuit chips.

The full name of CCD is charge-coupled device. It is also a semiconductor chip used to capture images. It reads pixel data through charge transfer.

However, CCD sensors require specialized manufacturing processes and are more expensive than CMOS.

However, CCD has an advantage: because it uses charge transfer, its resolution is relatively high and there is less noise.

However, if the design and manufacturing technology of CMOS are greatly improved, then the shortcomings of CMOS will become less and less, even in terms of resolution and noise, it will not be worse than CCD. In this case, the era of CMOS dominance has arrived. .

At the very least, in the previous life, by the 21s, even those so-called professional SLR digital cameras almost all used CMOS sensors, and CCDs had been eliminated.

What Zhang Zhipeng has to do now is also very simple. He must first manufacture the first CMOS chip he designed.

Then iterate on the basis of this chip.

As for other technical difficulties of high-definition cameras, Zhang Zhipeng has chosen to cooperate with other research institutes or professors.

He gives the standards and then lets the other party carry out research and development.

Of course, he will give the other party some scientific research funds.

This is called scientific research outsourcing.

Subsequently, Zhang Zhipeng plunged into the test workshop of Loongson Company. With the help of other scientific researchers, he began to manufacture the first CMOS chip he designed.

The manufacturing process also needs to be explored.

Because it is necessary to find out a reasonable manufacturing process.

After two or three days of exploration and experimentation, Zhang Zhipeng finally built the first CMOS chip he designed.

He went to see his partners again. More than half a month had passed, and some of them hadn't even started to work on it yet.

Some have just started and are going through the extremely difficult trial-and-error phase of research.

When Zhang Zhipeng saw this, he couldn't stand it.

Is this too slow?

However, he also knew that this was a normal scientific research situation.

It cannot be said that it is impossible to achieve results in ten days and a half like him, but it can only be said that it is very rare!

However, Zhang Zhipeng really can't wait.

So, he started helping these partners.

For example, one of his partners is a professor of optoelectronic information science and engineering at NPU.

This professor’s name is Wu Qingbo.

This person is also considered a famous expert in the research of optical lenses.

He once participated in research on the National Large Astronomical Telescope Project.

Zhang Zhipeng thinks that asking him to build a set of high-definition telephoto space telescope lenses should be considered childish, right?

But when he went to visit Wu Qingbo, he found that Wu Qingbo was looking through the information.

If Zhang Zhipeng hadn't come to visit him, no one would have known that Wu Qingbo planned to spend at least half a year researching relevant scientific and technological materials in the world.

Then, he planned to enter the laboratory and start doing research and development.

After hearing Wu Qingbo's plan, Zhang Zhipeng's blood pressure instantly increased.

I go!

According to Professor Wu's plan, it would probably take two years to complete a set of lenses, right?

Zhang Zhipeng said to Wu Qingbo: "Teacher Wu, I need very little time for this set of shots."

"How about we go to the laboratory and try to develop it while thinking about it?"

"I also want to learn some optical knowledge from you." Wu Qingbo said with a smile: "Comrade Zhipeng, you really can't be in a hurry when doing scientific research, and you can't be in a hurry!"

"You must be fully prepared before you can do your best!"

"However, if you are really anxious, then I will go directly to the laboratory and try to see if I can directly make a set of lenses that suit your requirements!"

Wu Qingbo has a pretty good personality.

He also followed the good advice. Zhang Zhipeng asked to start development immediately, so he immediately took Zhang Zhipeng into the laboratory.

Zhang Zhipeng didn't know much about optical lenses before, but he had a system to help him.

After spending two days in Wu Qingbo's laboratory, Zhang Zhipeng relied on the system to improve his optical lens design and manufacturing skills to an advanced level.

After being promoted, Zhang Zhipeng began to be busy in Wu Qingbo's laboratory.

Originally, Wu Qingbo was the protagonist, with Zhang Zhipeng as his assistant.

Later, everything changed.

Wu Qingbo became Zhang Zhipeng's assistant.

Under the leadership of Zhang Zhipeng, it took them only four or five days to come up with a set of long-focus space telescope lenses. Of course, large apertures and other arrangements were also made.

Most importantly, Zhang Zhipeng summarized a set of process manufacturing drawings for mass production.

After making it, I tested it and found that the performance of this set of lenses is quite excellent.

If you use this set of lenses to look at the moon on a moonlit night, you will be able to see the craters on the moon.

"Congratulations to Teacher Wu. Look, isn't this result coming out? We still have to get into the laboratory and seize the time to do things. Just checking the information and making preparations is just a waste of time." Zhang Zhipeng said with a smile.

Wu Qingbo himself knew very clearly at this moment: This set of shots was not created by him at all!

This is what Zhang Zhipeng did himself, okay? !

Wu Qingbo was very ashamed: "Comrade Zhipeng, this achievement is not mine."

"You did it, I was just there to help you."

Zhang Zhipeng said with a smile: "But if Teacher Wu hadn't taught me, I wouldn't have been able to make such a set of shots."

"Anyway, this still counts as your achievement!"

Wu Qingbo opened his mouth, not knowing what to say.

He blushed and said: "Then, I think it should be regarded as the achievement of both of us. When I write the paper, I will name you as the second author, okay?"

Zhang Zhipeng smiled and said: "Sure! Then do whatever you want!"

"However, when writing a paper, remember to keep it confidential and be sure not to write down specific parameters or anything like that."

Wu Qingbo nodded and said, "I understand."

In this way, Zhang Zhipeng helped his partners one by one, and finally developed the high-altitude high-speed digital camera as a whole in 1 days of one month.

He assembled the world's first high-altitude, high-speed digital camera and tested it specifically.

He stood on the roof of a tall building in Chang'an City and used this camera to record the scene on the other side of the Wei River, which is 20 kilometers away.

Through the telephoto adjustment, he could actually see the patterns on the clothes of the fishermen on the edge of the Wei River. Of course, the image is still blurry!

However, this already made Zhang Zhipeng very happy.

In the following time, Zhang Zhipeng designed a more superior CMOS chip and continued to try.

After trying it several times, the improvement in recording clarity is still very obvious.

Zhang Zhipeng thought again, everyone said that CCD cameras are clearer, so should I also study CCD and compare it with CMOS?

As soon as he said it, Zhang Zhipeng began to work on CCD sensors again.

No matter what, he wanted to compare.

What if CCD is indeed faster and clearer?

He knew: In the previous life, the main reason why CMOS eliminated CCD was that the manufacturing cost of CCD was much higher than that of CMOS.

In order to save more costs, merchants can only work hard on CMOS.

After another ten days of hard work, Zhang Zhipeng finally produced the process design drawing of the CCD sensor.

After it was developed, it was a lot more troublesome to produce samples.

Because CCD requires a unique process and cannot be produced like chips.

Therefore, it needs to develop a new set of manufacturing equipment and assembly lines.

Zhang Zhipeng can only figure it out by himself in the laboratory.

After pondering for more than twenty days, he finally made the first CCD sensor he designed.

After making it, Zhang Zhipeng immediately used it to install it with the parts he had made before, and also built another high-definition high-speed camera. .

Then, Zhang Zhipeng hurriedly tested it.

As a result, he discovered that CCD cameras are indeed much better than CMOS.

It can be seen that although the CCD model does consume more power and has a much higher manufacturing cost, it is indeed better to use than CMOS.

Zhang Zhipeng decided that it would be better to use a CCD for his high-definition digital camera.

Even if the cost of CCD is higher, so what?

This product will be used on unmanned reconnaissance aircraft in the future!

For this kind of product, under normal circumstances, you should not care about the production cost, but care about the shooting effect.

After getting the high-definition digital camera, Zhang Zhipeng felt full of accomplishment.

You know, this is only July 1993!

In this day and age, high-definition digital cameras are definitely an anomaly.

According to the trajectory of historical development, this thing should not have appeared until 2010.

This high-definition digital camera has quite a few uses.

For example, it can actually be used directly on fighter planes for taking photos and evidence collection. It can also be used on reconnaissance aircraft, which can help people on the reconnaissance aircraft discover what is happening below.

The human eye is far worse than this thing.

In fact, even though it is a high-definition digital camera, it can also be set to video mode.

If this thing is integrated with the aircraft's avionics system and allowed to automatically scan a wide range of the space below, abnormalities below should be quickly discovered.

Zhang Zhipeng thought this, and he felt a little excited.

He called Zhao Bingkun.

Zhao Bingkun received a call from Zhang Zhipeng. After he answered the call, he asked anxiously: "Have you already completed your unmanned reconnaissance drone project?"

Zhang Zhipeng smiled and said: "Director Zhao, how can it be so fast?"

"However, I have indeed come up with something good."

"I couldn't help but want to show it off to you."

Zhao Bingkun asked enthusiastically: "What good thing?"

"Just say it!"

"You know I'm impatient, but you kid still shows off!"

Zhang Zhipeng said: "I built a high-definition digital camera."

"Taking photos and videos will eliminate the need for film in the future. Moreover, the photos will be clearer. You can see people on the ground at an altitude of 20,000 meters!"

Zhao Bingkun was stunned for a moment: "What the hell?"

"digital camera?!"

"What is that?"

Zhang Zhipeng had no choice but to patiently explain to Zhao Bingkun.

However, Zhao Bingkun obviously still can't accept the fact that cameras or video cameras don't use film.

"Then let me go to Chang'an to have a look!"

"Comrade Zhipeng, you can always come up with something new!"

"And it sounds very useful!"

Zhang Zhipeng smiled and said: "Isn't this all to achieve better detection effects of unmanned high-altitude reconnaissance aircraft?"

"Actually, the technological content of this unmanned reconnaissance aircraft is really very high."

Zhao Bingkun was originally a very busy person.

He has a lot of things to do.

But he did his own calculations and found that in the past two years, he had gone to Chang'an City surprisingly many times, dozens of times in total.

Sitting on the plane, he was still thinking: "If Zhang Zhipeng can produce an important result in one day, then I don't need to run away at all. I can just live in Chang'an City and wait for applause with a grin on my face."

Zhao Bingkun soon arrived at the military airport in Chang'an.

Zhang Zhipeng came to greet him personally.

He also wanted Zhao Bingkun to experience high-tech achievements as soon as possible.

"Director Zhao, welcome!" Zhang Zhipeng greeted Zhao Bingkun with a smile.

Zhao Bingkun came over and patted Zhang Zhipeng's shoulder heavily and said, "Comrade Zhipeng, do you know which city I have visited the most in the past two years?"

Zhang Zhipeng smiled and said: "Chang'an?"

Zhao Bingkun laughed: "That's right! I have been here more than 30 times in more than two years, on average once a month, and sometimes twice a month!"

As he spoke, his eyes glanced at the digital high-definition camera slung on Zhang Zhipeng's left shoulder.
