Chapter 41 The Porter of Knowledge
The increase in the scale of transistors will make this method encounter more and more difficulties. The reliability will drop sharply, making it impossible to solve or even unusable, such as electromagnetic interference and ringing. , ground bounce reflection, signal crosstalk, etc.
The scale is just right now, the number of transistors is not very large, the price is not too high, the performance is appropriate at this stage, and the functional architecture still has advancement and development potential.
Architecture, this is what Gao Zhendong is so excited about. The architecture and instruction set of 8008, 8080 and 8086 are inherited.
Purely theoretical things aside, the entire computer technology he learned in his previous life is inseparable from this set of architecture, which is very beneficial for him to use this set of things in the shortest possible time.
Although there may be some changes in performance, Gao Zhendong is already very satisfied. This is a miniaturized all-transistor computer. You must know that domestic transistor computers are from the generation of 441B-1, 109, and 119 computers in the mid-1960s. Things have happened, and all-transistor computers will come even later.
At this point in time, Gao Zhendong understands very well what a better, easier to produce, and cheaper computer means. The hero who lit up the sun worked on the 119 aircraft for three months and shot the squirrel.
Gao Zhendong suppressed his excitement, put everything into the storage room, ran to wash his face, picked a soothing music record and put it on the gramophone, lying on the chair quietly Listen.
The blood is a little boiling, so calm down, otherwise he is afraid that he will develop high blood pressure.
Amidst the melodious music, Gao Zhendong rested for about 20 minutes before sitting up, taking out the DRAM and CPU explanatory materials from the storage library and reading them carefully.
DRAM is relatively simple. The four boards all have the same three-tube memory unit. Because of the single structure and simple circuit arrangement, four circuit boards are installed. The row of interfaces on the top circuit board is the C1103 chip. Functional reproduction of 18 pins.
CPU is a little more complicated. Since its functional units are different, such as adders, registers, instruction sets, etc., the system separates each functional unit of the CPU and implements them on different circuit boards. The bus connects each circuit board and provides a power supply, clock source, necessary auxiliary circuits, etc. that can be directly connected to the existing mains.
In fact, this CPU cabinet only needs to be equipped with RAM, program memory (similar in function to today's hard disk), plus input and output devices, and it can be put into programming.
Where is the CPU cabinet? This is simply a minicomputer.
This made Gao Zhendong very happy. It saved him a lot of trouble. He didn't feel that he was embarrassed in any way because he had less to study personally.
He has a very clear positioning of his current stage. He is not an amazing genius. He does not produce too much knowledge. He is more of a porter of knowledge.
As long as there is an opportunity, he will try his best to let future knowledge shine through in this era to the greatest extent possible, so that some things can avoid detours and other things can develop faster. , he felt it was worth it.
However, during the transportation process, he also had to integrate it, teach others, and carry it forward, and he also contributed his own strength.
Looking back, although these two things are good, he didn't have a good way to come up with them for a while. Think about it, there are more than 200 direct researchers of the 103 machine, and he only knows one It's an exaggeration for people to take out these two things at once.
And the price of researching this thing is really too high for an individual. Even if he has the finished product, he can't explain how the spare parts for the finished product were obtained.
Gao Zhendong is not worried. There are always ways. If he can't find a way, it might be a good idea to go directly to the entrance of the 15th machine department and throw it there on a dark and windy night. Personal honor will be put first. On the other hand, let's send the things out first. In his situation, there is always no shortage of personal honors, but he hasn't reached that stage yet.
Thinking of this, Gao Zhendong calmed down immediately. It was a good thing that he got the thing.
The next step for him is to take the time to copy books, yes, those two explanatory materials on DRAM modules and CPU cabinets. The printed versions of these two books provided by the system cannot be taken out. Meet people.
And he has another consideration. He is an automation major. Although he has not learned much about computers in this life, he has learned digital circuits, microcomputer principles, assembly language, operating systems, data structures, etc. in his previous life. There are many professional courses to learn. By copying the book yourself, you will basically fully understand the principles, architecture, and instruction set of this CPU. This will be beneficial for quickly training personnel and accelerating its use and promotion.
In addition to copying books, he also had to program the machine to run and use it. Gao Zhendong was not planning to build an operating system for the time being, as that would take too long.
He plans to use the previous generation microcontroller as a data acquisition device and write a simple loop watch program instead. For non-universal specific functions, this method is less expensive and effective, but he has obtained these. What comes after input and output devices.
Gao Zhendong put the two explanatory materials into the storage warehouse and raised his hand to look at his watch. It was almost dinner time. He decided to have a good meal to celebrate today's harvest.
Just as he was about to take action, "Dong...dong...dong...", the door rang.
When I opened the door, I saw Silly Zhu at the door.
Silly Zhu saw Gao Zhendong and invited him: "Let's go, Zhendong, go to my house for dinner."
This is really a sleepy pillow, Gao Zhendong was not polite: "Okay."
Two The man walked towards Sha Zhu’s house. Gao Zhendong asked as he walked: “What’s good today?”
Si Zhu shook his head: “It’s nothing big, it’s just that the brother of a clerk in the Publicity Department got married. , I'm going to take care of the dishes. After the work is done, the master also gave me some things. I often eat from you. This time, I want to have a good time with you."
I thought about it and told him again. : "Don't go home to get the wine, I'm here to treat you thoroughly today."
Gao Zhendong remembered that the day before yesterday, Sha Zhu had performed another play with Xu Damao.
He didn't shirk, but when he tried to shirk, Si Zhu became anxious with him: "Okay, I'm a fool today, I'm going to give you a grain of rice, I'm a grandson."
As soon as they finished speaking, the two of them had already arrived at the door of Shazhu's house. He Yuyu came up to him: "Brother Zhendong, you are here."
Gao Zhendong became accustomed to it and took out two Sugar: "Here! Sweet mouth."
Silly Zhu looked at Gao Zhendong and laughed: "Sun Zei!"
Gao Zhendong didn't know whether to laugh or cry, and gave a weak kick: "Get out!!!"
He got some free time in the morning and made the first move.
I made up the nonsense about the 15th Machinery Department. If you are interested, you can search online and you will probably know which department it is.
Yesterday, I received over 100 recommendation votes, which made me so happy. Yes, other data is OK, thank you everyone
