Siheyuan: The Era of Core Generation

Chapter 91 Modular Design

Zhao Ye finished arranging the lithography machine, and then devoted himself to the design of the core functions of the processor again.

Regarding this matter, Professor Ci and the other three professors have not missed a lot of make-up lessons during this time.

Not just the three of them, behind them is a huge support team.To put it bluntly, the three of them are just coordinating and organizing work, and of course planning and leading the entire design.

Many excellent students and professors from the electrical, electronic and mathematics departments of the two schools are contributing to this design effort.

Zhao Ye's blood was surging when he heard such a summary.He and the three professors spent five or six days together planning the architecture and basic logic design of the entire processor.The next work is to study different mathematical models according to different instruction set settings, and then restore these mathematical models into circuit designs.

Try to use the most concise mathematical model and circuit to realize the idea proposed by Zhao Ye and others.

The time was tight and the task was heavy. After the three professors finished the preliminary work with Zhao Ye, they also left here to go to the school to organize this integrated circuit design competition.

Zhao Ye solved this problem, and then devoted himself to other work. In this project, he is like a firefighter. He will step in whenever there is a problem in any link.This can't be helped, those who can do more work.

Besides, it was the first time for others to do such a thing. Zhao Ye was the chief designer and had successful experience. Everyone also subconsciously piled some problems on him.

When the supervisor encountered problems with input and coding, Zhao Ye asked them not to do it behind closed doors, but to mobilize the teachers and students of the literature department in the university as much as possible to do more repetitive tasks.

For example, the coding work of the glyph library is all about distributing a manuscript paper printed with ten by ten squares to hundreds of students, and then asking them to color in the grid with a pencil to form Chinese characters one by one.

Each person is responsible for hundreds of such glyph designs, and they have to check and modify each other after they are done, trying to make the glyph design more reasonable.

The basic common characters are also in this mode, allowing the teachers and students of the Department of Literature to classify Chinese characters, the codes of commonly used characters are first, and the classification and coding are carried out level by level.

I also asked someone to make a model of the input keyboard, and studied the layout a little bit.

The display equipment group also has constant problems. The backplane, liquid crystal panel, and polarizer have to use glass, which also involves technical difficulties such as drawing circuits on the glass.Zhao Ye directly threw out a mature technical solution in this regard.This solution may not be advanced enough, the yield may be low, and it may consume a lot of materials and labor.But this is a mature solution, and it is also the most suitable solution for this era.

As Factory 718 produced suitable glass plates, and the chemical laboratory produced suitable liquid crystal materials, Institute 611 produced usable storage devices.The progress of the entire display is ahead of the other groups.

At the beginning of the design, Zhao Ye's goal was only to reach a display screen of 718 square centimeters, which is almost usable.However, after the 25 factory got Zhao Ye's process plan, the technicians did not stick to that design, but conducted more demanding tests on this basis, and successfully produced thin glass with a length of [-] centimeters and a width of [-] centimeters. plates, polarizers and other products.This also gave Zhao Ye the conditions to make a larger display.

The resolution should not be too high. The current dot-matrix display can achieve [-] dots per square centimeter, which is the limit of this era.In this way, there are still several key processes that have not been successfully tested.

Larger screens correspond to more complex circuit printing, larger display buffers, and more complex production of display chips.

Zhao Ye couldn't make up his mind for a while. Professor Chen, who is in charge of this research work, proposed that the current ten-by-ten screen is the main one. If the development of a larger screen can keep up with the progress of the project, then it will be changed to a bigger screen at that time. It's all right.

One word awakened the dreamer, Zhao Ye immediately adopted this suggestion.Not only that, but it also reminded him of a problem he had overlooked before.

Motherboard!

At this time, Zhao Ye had not proposed the concept of the motherboard, and everyone did not have this understanding either.All systems and components are directly welded to each other.If you want to change any parts in the future, you can only disassemble and re-weld.

It not only affects the efficiency, but also increases the risk, and is not conducive to the upgrading of products.

Zhao Ye is determined to make up for this loophole, and it's not too late.

So, with the help of the spiritual space, Zhao Ye distributed such things as standard interface design specifications for subsystems to each group in less than two days. For the design of the display circuit, they are required to be in the In the interaction, what kind of interface line should be designed.

What kind of interface circuit planning does the memory have, what kind of interface circuit planning does the processor have, and the same is true for input devices.

Zhao Ye thought about it, should he reserve ports for all the things that will be used in the future?Such as sound!
But after thinking about it, he didn't do that.

The current motherboard should not be designed so complicated.Very simple, the team has no experience!
After this project is over, everyone has corresponding design experience, and it is not too late to put forward more complex usage requirements.After all, he was only using it as a scientific calculator in the first place.

Zhao Ye's request did not arouse everyone's big ideas. It was just a standard, and there was nothing special about it.Mainly, this has no conflict with the current circuit design work.It's just in some places, just pay a little attention.

No one expected what kind of role their design would have in the future.

Time passed day by day, and the design work of each subsystem was carried out in an orderly manner.After everyone passed the initial confusion, the work became more and more handy.

The circuit of the display system was designed first.This itself is not too complicated, and Zhao Ye did not pursue too much in terms of space. It is just a matter of changing a "graphics card" in the future. This does not need to be too harsh.

It's just that this kind of "graphics card" basically corresponds to the display screen one by one.That is to say, which type of display screen should correspond to which type of "graphics card".For example, the current "graphics card" only corresponds to the ten-by-ten display that will be used.In another way, then the "graphics card" will be redesigned.

The "graphics card" has been made, but it cannot be tested yet, because the screen has not been made yet.Currently the display is stuck with the injection of the liquid crystal and the printing of the circuit on the glass plate.Zhao Ye didn't intervene too much, and let Professor Chen lead a group of people to scratch their hair there.

Zhao Ye believes that these people will definitely find a way, and he firmly believes in this.

He has more important work to do now, because all the parts of the lithography machine have arrived.Now he is gathering more than a dozen experts to assemble this real lithography machine.
