Chapter 41: Knowledge Porter
As the size of transistors increases, this method will encounter more and more difficulties, and its reliability will drop sharply, becoming unsolvable or even unusable, such as electromagnetic interference, ringing, ground bounce, signal crosstalk, etc.

The current scale is just right, the number of transistors is not too large, the price is not too high, the performance is appropriate at this stage, and the functional architecture is still advanced and has development potential.

Architecture. This is also the point that Gao Zhendong is so excited about. The architecture and instruction set of 8008, 8080 and 8086 are inherited.

Putting aside purely theoretical things, the entire set of computer technology he learned in his previous life is inseparable from this architecture, which is very helpful for him to use this set of things in the shortest time.

Although there may be some fluctuations in performance, Gao Zhendong is already very satisfied. This is a miniaturized all-transistor computer. One should know that domestic transistor computers are from the mid-60s, the generation of 441B-1, 109, and 119 computers, and all-transistor computers were even later.

At this point in time, Gao Zhendong understood very well what better, easier to produce, and cheaper computers meant. The hero who lit up the sun was the one who worked on the 119 machine for three months and shot the squirrel.

Gao Zhendong suppressed his excitement, put all his things into the storage, ran to wash his face, picked a soothing music record and put it on the phonograph, then lay in a chair and listened quietly.

His blood was boiling, and he needed to calm down, otherwise he was afraid he would develop high blood pressure.

Amid the melodious music, Gao Zhendong rested for about 20 minutes before he sat up and took out the instruction materials on DRAM and CPU from the storage library and read them carefully.

DRAM is relatively simple, with the same three-tube storage unit on all four boards. Because of its simple structure and simple circuit layout, it can be installed on four circuit boards. The row of interfaces on the top circuit board reproduces the function of the 4 pins of the C3 chip.

The CPU is a bit more complicated because its functional units are different, such as adders, registers, instruction sets, etc. The system separates the various functional units of the CPU, implements them with different circuit boards, and then connects the circuit boards with a bus. At the same time, it provides a power supply that can be directly connected to the existing AC power, a clock source, necessary auxiliary circuits, etc.

In fact, this CPU cabinet only needs to be equipped with RAM, program memory (similar in function to today's hard disk), and input and output devices, and it can be put into use for programming.

This is not a CPU cabinet at all, it's simply a minicomputer.

This made Gao Zhendong very happy. It saved him a lot of trouble. He didn't feel embarrassed that he had less research to do.

He has a clear understanding of his current stage. He is not some brilliant genius, and he does not produce too much knowledge. He is more of a knowledge carrier.

As long as there is an opportunity, he will do his best to let the future knowledge shine in this era in advance, so that some things can avoid detours and other things can develop faster. He thinks it is worth it.

However, in the process of moving, he also needs to integrate what he has learned, pass it on to others, and carry it forward, thus contributing his own strength.

Looking back, although these two things are good, he doesn't have a good way to produce them at the moment. Just think about it, there are more than 103 direct researchers on the 200 machine, and you can imagine how exaggerated it is for one person to come up with these two things at once.

Moreover, the price of researching this thing is too high for an individual. Even if he has a finished product, he cannot explain how the spare parts of the finished product were obtained.

Gao Zhendong was not worried. There was always a way. If he really couldn't find a way, he could just go to the entrance of the 15th Machine Department on a dark and windy night and throw the things there. It might also be a good idea. Putting personal honor aside, he would send the things out first. Given his situation, he would always have personal honor, but it hadn't come to that stage yet.

Thinking of this, Gao Zhendong calmed down immediately. He got the thing, and it was a good thing. This was a good thing.

The next step he had to take was to find time to copy books, yes, to copy the two instruction books on DRAM modules and CPU cabinets. The printed versions of these two books provided by the system could not be shown to others.

He also had another consideration. He majored in automation. Although he didn't learn much about computers in this life, he learned a lot of professional courses such as digital circuits, microcomputer principles, assembly language, operating systems, and data structures in his previous life. If he copied the book himself, he would basically fully understand the principles, architecture, and instruction set of this CPU, which would be beneficial for quickly training personnel and accelerating its use and promotion.

In addition to copying books, he also had to write programs to make the machine run and be used. Gao Zhendong was not planning to make an operating system for the time being as that would take too long.

He planned to use the method of using single-chip microcomputers as data acquisition devices in his previous life and write a simple loop duty program instead. For non-general specific functions, this method requires little investment and has a quick effect. However, these are things he will do after he gets the input and output devices.

Gao Zhendong put the two explanatory materials into the storage room, looked at his watch, and saw that it was almost time for dinner. He decided to have a good meal to celebrate today's harvest.

Just as I was about to take action, the door opened with a sound of "Knock...Knock...Knock..."

When I opened the door, I saw Shazhu standing at the door.

When Sha Zhu saw Gao Zhendong, he invited him, "Come on, Zhendong, let's go to my house for dinner."

This was really like a pillow for a sleepy person. Gao Zhendong didn't hesitate: "Okay."

The two of them walked towards Sha Zhu's house. Gao Zhendong asked as they walked, "What good news is going on today?"

Sha Zhu shook his head: "It's nothing big, it's just that the brother of a clerk in the Propaganda Department is getting married, and I went to cook. After the event was over, the host family not only gave money but also some food. They often eat your food, so this time I wanted to have some fun with you."

After thinking for a while, he reminded her again: "Don't go home to get some wine. I'll come and treat you thoroughly today."

Gao Zhendong remembered that the day before yesterday, Sha Zhu and Xu Damao had put on a show about the cooking of this meal.

He didn't refuse. If he did, Sha Zhu would get angry with him: "Okay, today is all yours. I want to give you a grain of rice. I am your grandson."

Just as they finished speaking, the two of them had already reached the door of Sha Zhu's house. He Yushui came up to them and said, "Brother Zhendong, you're here."

Gao Zhendong got used to it and took out two candies: "Here! Sweeten your mouth."

Sha Zhu looked at Gao Zhendong and laughed: "Sun Zei!"

Gao Zhendong didn't know whether to laugh or cry, and kicked him: "Get out!!!"

　I got some free time in the morning, so I posted it first.

　　I just made up the name of the 15th Ministry of Machinery. If you are interested, you can search it online and you will probably know which department it is.

　　Yesterday, the number of recommended votes exceeded 100, which made me very happy. The other data are also good. Thank you everyone
