Chapter 260 The Temptation of Going Home
After Zheng Liangshu left with the people from the Beijing Steel Plant, Gao Zhendong called Liu Gong from the Beijing University of Technology and informed him that the development of steel was officially on the schedule.
Liu Gong was very happy when he heard the news. Director Gao acted very quickly.
Gao Zhendong made these three kinds of steel with great fanfare. The main reason is that gun steel has an advantage. Basically, one kind can be used for a long time without replacement. Even if he gives the good steel to the soldiers in advance, they can use it first. .
At this point, the matter of gun steel is basically settled. Even this type of steel may not necessarily come back to the rolling mill. Although ESR is used, the Beijing Steel Plant is also here at the third rolling mill. After receiving ESR production conversion training, we also directly ordered several sets of ESR furnaces for the third rolling mill.
Yes, now the Third Steel Rolling Plant not only rolls plates and produces some special steels such as thermocouples and 591, they also produce ESR equipment, which is simply the meat and potatoes of the Seventeenth Machinery Department.
Although the equipment production capacity is slightly tight, the Beijing Iron and Steel Plant still has preferential treatment here. There have been many exchanges between the cadres of the two plants. From the factory leaders to the middle-level and even the grassroots, there are comrades who have worked in both plants. Not a few.
Gao Zhendong himself went back and continued to debug his single board computer.
The register has been debugged. The advantage of the register is that these things basically have the same structure. Once one is done, the others will be almost ready. After all, although the integrated circuit manufacturing process these days is very low , but the consistency is still good, as long as the unit circuit of the register is basically the same.
And there is something slightly special about the 8008's registers. Each bit unit of its register is different from the fact that most of the later CPU's registers were implemented using latches. It uses a DRAM implementation. It was implemented with three transistors, probably because Blue Factory was good at DRAM back then.
The transistor memory developed by Gao Zhendong is based on the earliest commercial DRAM chip, C1103. In other words, the basic unit of the register of this thing is the same as the basic unit of the transistor memory made by Gao Zhendong, which greatly facilitates his debugging of the register.
What he is working on now is the implementation part of the instruction set. The formal name can be called instruction logic decoding.
The implementation of the CPU instruction set usually has two methods: hard wiring and microcode, or a combination of the two.
They determine what operations the CPU will perform after obtaining each instruction. It can be regarded as decoding the logical operations required for machine code instructions, that is, based on the input machine code instructions, the output Control signals of other circuits of the CPU to realize the specific function of a certain instruction.
In C8008, the instruction set is implemented through the hard connection of the programmable logic array.
The DJS-59, which was born out of C8008, and the simplified single-board computer based on DJS-59, undoubtedly use this method. The advantage of hard connection is good performance under the same conditions, but the disadvantage is lack of flexibility.
However, for the first-generation CPU of the size of C8008, the requirement for flexibility is a bit too much. It uses hard connections to implement machine instructions.
What’s interesting is that although this set of things clearly exists in the CPU, the existence of this set of things may not be seen in many introductory CPU-related textbooks or CPU architecture descriptions and user manuals. , or just brush it off without saying much.
Because it is different from the registers, buses and other things in the CPU, it is transparent to most users. No matter how low-level users, there is no need to pay attention to this set of things.
As for Gao Zhendong, there is no such method of using programmable logic arrays to implement hard connections, and it is useless. There is no such thing at the moment. The hard connections are directly welded, which can be easily understood. In order to connect directly with a line, of course it is not that simple in fact.
These things are different for each instruction, so they have to be debugged one by one. The entire 8008 instruction set has dozens of instructions. Although it has the foundation of DJS-59, there is still a lot of work.
Because this thing is different from ALU and registers, the instruction decoding circuit of the previous instruction basically does not have much guiding significance for the subsequent circuit.
Gao Zhendong once again became the "Welding Emperor" during debugging. It is estimated that he will have to wear this title for a while.
Gao Zhendong, who was dizzy from the instruction implementation unit, got off work and cycled home.
I happened to meet Xie Jianye at the door of my house, and the two chatted for a while. Xu Damao, who was passing by, felt even more angry when he saw this situation. Xie Jianye was still studying film screening with him today, could he recognize him?
Well, Gao Zhendong, you robbed my wife and helped your friends steal my job. This is too much! I must do it.
What to do with Gao Zhendong? Xu Damao couldn't think of it for a moment. He doesn't have the ability, you know.
However, this thought has been lingering in his head, getting into trouble. In short, he just wants to cause some trouble for Gao Zhendong.
Gao Zhendong didn't know what Xu Damao was thinking. He chatted with Xie Jianye for a few words before saying goodbye and entering his home.
As soon as he entered the house, Lou Xiaoe came up to him, took his bag and put it away, and then brought him a cup of hot tea.
This was the first time since the two got married that Lou Xiao'e welcomed Gao Zhendong seriously after get off work. The previous work had been disrupted by various things, such as the renovation of the south room.
As a result, Lou Xiaoe never had the opportunity to show her mother's teachings, which made her very depressed. Today she finally had this opportunity, but she felt positive.
The tea has been brewing for a while, and the temperature is almost right. The light green tea soup in the glass is clear and transparent, and the green tea leaves are floating in it, emitting a slight steam, which is really beautiful.
Gao Zhendong immediately felt the feeling of "home". It's not bad, he thought happily. Lou Xiao'e smiled and said: "Drink a glass of water first, the food will be ready soon."
Before getting married, Gao Zhendong would have to work hard for forty or fifty minutes before he could have a hot meal when he came home from work, unless he went to Sha Zhu's place to get some food or had already settled the matter outside.
While drinking tea, Gao Zhendong helped Lou Xiaoe arrange the table, but he remembered a TV series he had heard in his previous life, "The Temptation of Going Home". He had never seen the specific content. However, he felt that the name had something to do with it.
After laying out the food, Lou Xiaoe poured Gao Zhendong a glass of wine, her eyes shining: "Zhendong, eat~~~"
Gao Zhendong was a little crazy for a moment, and picked up the wine Cup: "Well, let's eat~~~"
After eating, Lou Xiao'e cleared the table, and Gao Zhendong got into the south room and began to continue writing the operating system.
After a while, Lou Xiao'e packed up her things after dinner, took her review textbook, and entered the south room, reviewing next to Gao Zhendong, asking Gao Zhendong a few words from time to time.
The faint sound of music lingers between the two of them, and the years are quiet.
——
The next day was Sunday, but Gao Zhendong still got up early, gently put the quilt back on Lou Xiao'e, and went out to box for exercise.
After a set of punches, Gao Zhendong felt full of energy and energy.
Turning around, Yan Bugui was standing next to him.
Gao Zhendong had actually seen him a long time ago, and he felt a little strange. Even if Yan Bugui got up so early, he would usually be busy with breakfast at home, but it was strange today.
But I have already started to punch, so there is no need to stop for him. I guess he has nothing urgent to do, and it is important to exercise.
Seeing Gao Zhendong finish his punch, Yan Bugui had a smile on his face: "Good morning, Zhendong. You did a good job with your punch, full of momentum."
He didn't understand. He doesn't know Bajiquan, or any boxing at all, but he can still boast casually.
Gao Zhendong moved his hands and feet gently and said modestly, "Good morning, Teacher Yan. I've been doing this for many years and it's okay, haha."
I saw him walking towards the door of his house while talking. , Yan Bugui was anxious, he was about to enter the house, wouldn’t I be freezing in vain? It was still quite cold in the morning at the end of March in Beijing.
He quickly called Gao Zhendong: "Zhendong, there is something I want to discuss with you."
I knew something was wrong with you, and I thought you could bear it. Gao Zhendong was actually not very willing to talk to him. It didn't mean that he was bad. He just had to calculate everything, and dealing with him was sticky and not smooth at all.
Gao Zhendong stopped and said with a smile: "What's the matter, tell me, Teacher Yan."
"That's it, that thing about Beijing Radio and Television University."
Beijing Radio and Television University has already started school on March 8. Ding Yongnian and Qin Huairu both got their wish. Although both of them applied for preparatory courses, even Qin Huairu finally chose to go first. I was transferred to a single subject, but I was still very excited, and I talked about it a lot in the yard.
At the same time, Yan Jiecheng also went to work in the factory. Well, he and Xu Damao were in the same workshop, but they were not in the same team.
Although there are other veteran comrades and skilled workers in the team, it is still not suitable for two pure newcomers to work in a team. This kind of thing will not happen even if you have not taken the "Safety Production Management System" class. So arranged.
Yan Jiecheng went to work, and gradually understood what the "TV University" suggested by Director Gao to his father was about. In his opinion, it was a proper university.
He had graduated from high school, so it was natural for him to go to this TV university, and he had a good foundation. Isn't this much better than a junior high school student from a rural area like Qin Huairu?
When he thought that this opportunity was taken by a rural woman who dropped out of high school, no, even graduated from junior high school, he couldn't help but feel sad and beat his chest.
In the past ten or twenty days, he has been complaining about his father at home. Director Gao gave him a chance, but his father was useless.
After hearing this, Yan Bugui felt quite regretful. How could he get into money and be unable to get it out? When had Director Gao ever tricked someone?
So he has been looking for opportunities to see if there is room for change in this matter and whether Boss Yan can be added to the matter.
It's just that Gao Zhendong has been very busy recently with work and marriage. At least he couldn't catch Gao Zhendong very much. He did see Gao Zhendong on the wedding day, but if he went to Gao Zhendong to talk about it that day, any fool would know that. Not suitable.
