Chapter 224 The Youth of Computers
Unlike the people in the Communications Institute, the leaders of the 12th Machinery Department took this news and felt as comfortable as drinking Ice Cream in the dog days of summer.
Resisting the urge to grab people from the 17th Machinery Department, he said to himself: "Message transmission, file transmission, what the telephone network can do is not just making phone calls. , haha."
Looking at the last few lines of the report material of the computing office - "This is a big matter. How to use it, I hope the ministry and relevant units will demonstrate it as soon as possible and make a decision quickly, so as to realize its benefits as soon as possible. . ”
“This thing is indeed a little too convenient. It’s good, but it’s true that they can’t make a conclusion on this matter. We have to sit down and discuss it together. By the way, there is also the blacksmith from the 17th Machinery Department. He is theirs and cannot be ignored.”
The leader was talking to himself and calculating.
So Gao Zhendong, who returned to the third rolling mill from the operation office, received a notice to go to the 12th Machinery Department for a meeting on Saturday afternoon when he was about to get off work.
Today is Thursday. The reason why I didn’t go the next day is mainly because it is really difficult for the participants to find time. They are all busy people with many things to do. If I can get it together for you in a day and a half, it is considered an exception. What more bikes do you want?
But not to mention, there are quite a lot of exceptions here in Gao Zhendong. Every time he makes a move, he can alert the leaders of the 17th Machinery Department, the National Defense Work Committee, and the 12th Machinery Department. people can be considered an anomaly.
After receiving the call and writing down the meeting arrangements in his work diary, Gao Zhendong put the matter aside for the time being. He turned around and started working on another circuit board made for him by the computing institute. things.
Yes, it was the subtraction electronic device that Gao Zhendong was inspired to think of when Su Weihua came to solve the problem of the anti-ship missile losing altitude last time.
The circuit board calculation station has been completed. The electronic components were obtained by Lou Shouxing from Western countries through Hong Kong Island channels and had been sent to him a long time ago.
This thing is actually simple to say. He wants to make some simplifications on the basis of DJS-59, and use the integrated logic gate circuits that have just appeared to make a smaller and streamlined version of DJS- 59 out.
This thing, in Gao Zhendong's design, is different from the DJS-59, which consists of many 50*50cm circuit boards. It is only composed of circuit boards with a total area of 50*50cm.
This 50*50 total area integrates a streamlined version of the DJS-59 all-transistor computer and the necessary input and output interfaces, as well as 96 bytes of transistor memory as running RAM, and more RAM and The program is stored in ROM in the form of a plug-in.
This is Gao Zhendong’s idea. The integrated circuit technology for single-chip microcomputers is currently immature, so I can do subtraction and add the newly born integrated circuit chips to make a single-board computer, right?
This single board computer does not need the "powerful" performance of DJS-59, about half of it is enough. The more important requirement is that it can be compatible with the DJS-59 architecture and use most of the DJS-59 software. Just resources.
What this youth version of DJS-59 wants is to be "extremely small" in size and consume less power to complete basic calculations, so Gao Zhendong even integrated 96 bytes of RAM.
Don’t underestimate this thing. With this thing, the application range of computers can be greatly expanded. That little computing power will seem insignificant in the future, but at this time, it can really do it. Quite a few things.
To give an imminent example, once this thing is completed, Gao Zhendong will equip his home with a set of XS-59 and JP-59, and he will be able to program software at home again. Now the DJS-59 It was really inconvenient to be in the factory.
In Gao Zhendong's plan, single-board microcomputers are used as substitutes for microcontrollers to complete the work of embedded systems and some personal PCs, while DJS-59 and the second-generation computer he designed are used as medium and large computers. .
In order to achieve this goal, we rely on integrated logic gate circuits that have just appeared.
Although the integrated logic circuits at this time are not as diverse as the 74/54 series and CD4000 series in the future, the multi-channel integrated OR gate, AND gate and NOT gate chips that I just bought are enough. He was having fun. These three logic gates are the basis of all other logic gates.
On an integrated logic circuit, there are often four to seven of the above-mentioned basic logic gate circuits, which means that one chip can replace several or even dozens of transistors in the past.
Coupled with the saved area of RC components, the area saved is directly several times or even ten times more.
With a little excitement, Gao Zhendong started debugging the single-board computer.
The subtraction has been done a long time ago. Gao Zhendong has designed the single-board computer circuit using OR gate, AND gate and NOT gate.
However, the difference from DJS-59 is that DJS-59 is a copy, and this time it is a serious design of our own. Although there are a lot of achievements of DJS-59 to learn from, this is still a new set of things. .
The integrated circuit is new, the circuit diagram is new, and the circuit structure can also be considered new. The compatibility with DJS-59 must also be considered. Debugging is not a small task.
Thinking of this, Gao Zhendong sorted out the things he had not finished or was planning to do.
Material lines: single crystal furnace, tungsten-copper material, tungsten-molybdenum alloy, and three types of firearm steel approved by Beijing University of Technology. The progress of the first three is pretty good, especially the single crystal furnace. Judging from the report Gao Zhendong received, it is already coming to an end. The latter three haven't started yet, but that stuff is very easy for Gao Zhendong. Who can't copy the answers?
Information technology line: "Principles of Automatic Control", single board computers, second-generation computers, operating systems, network technology, C language.
"Principles of Automatic Control" is a long-term matter and cannot be rushed. Single-board computers are being developed. The second-generation computer has not yet started. It is now undergoing its precursor work, such as single-crystal furnaces. The operating system is being improved step by step, and about half of it has been completed.
In terms of network technology, the current ones are enough for the time being, and more will have to be released later. There will be no environmental conditions for the application of new technologies in one to two years, so you can prepare slowly.
C language is waiting for training after marriage, and there is nothing else to do.
Management line: Nothing is going on for the time being, and Gao Zhendong is not ready to put more effort in this area for the time being. As for the "Safety Management System" training, the 17th Machinery Department and the factory are arranging it. It's not long after the Chinese New Year and it hasn't started yet. Just wait until it starts.
As for other things, even something as important as the ruby laser, in Gao Zhendong's opinion, is just a job or an auxiliary, not considered his serious work, he can just participate when the time is right.
Looking at it this way, there is still not much work, but there is still a lot of time. I was scared to death, and I thought I didn’t even have time to get married.
He patted his chest and continued working.
——
At the same time, Mr. Kramer, deputy editor-in-chief of the AIEE journal, received a thick letter from an old friend.
The letter must have been opened. Cramer didn't care about this. It was strange that it had not been opened and checked. For a letter from that country in the east, it would be impossible for Cramer to travel to the Lanley Center first. Mo was the first to not believe it.
After all, I was beaten violently on the other side of the world just a few years ago. I was beaten twice and a half by ten or twenty people. If I sit down to negotiate, I will lose. What’s more, since the end of that country in the East, , was pushed all the way back from the river.
He couldn't wait to open the letter. The letter was written in the familiar handwriting of an old friend.
"The C language researcher has improved his standards and added the missing parts in the original haste. They are in the attachment of the letter. I hope they can be helpful to you, and I hope you will stop complaining about its difficulties every day. This is a beautiful computer language, my friend, and it does not deserve to be treated like this."
Well, if there is indeed a standard supplement in the letter, I promise to tone down my complaints. Half, oh no, a third, no more!
Kramer looked at the letter and thought to himself.
However, the next content of the letter made him sit upright instantly and became energetic. No wonder Lanli's people did not stop the letter. After all, they were reluctant to give up on such a thing that could take advantage of them. .
“If necessary, we can provide the compiler source code and instructions for this language. Of course, you need to solve two problems. One is how to transplant it to your machine. How does your machine compare with ours? is different.”
"Second, you have to find a way to deal with the curious ghosts in the Lanley Center. You know, they may not be so friendly to everything from us."
Kramer couldn't help but cheered, source code? This is great. Missing standards and obscure content make it difficult to implement a C language compiler. With source code from its creator, all this will be solved.
As for the people at Ranley Center? There is no need to deal with it, this gift from God is what they long for every day.
This should be the biggest reason why this letter got to me, because like the previous letter, it has benefits.
However, the next paragraph of the letter made Kramer jump out of his chair. Oh my God, what did I see? You finally favor your poor believer and want to redeem me?
"Mr. ZhenDong.Gao, the creator of C language, felt that the C language standard was too unfriendly to beginners. He wrote a book about C language, with some concise but effective exercises, dedicated to making all Everyone can appreciate the 'elegance' of C language. If you need it, I can try my best to promote the publication of this book at your place. Of course, this requires your cooperation. I think you will be happy to serve Mr. Gao. , isn’t it?”
I do, of course I do, Kramer danced.
I swear on my salary, Lanli’s gang of writers will definitely be willing too! !
Cram couldn’t wait to take out a pen and paper and began to reply to his friend in the East.
“My dear friend.”
