Chapter 654 The world’s first central processor (five chapters today, two chapters first)
In fact, he is not the only one who has thought of this. All the leaders of ministries and commissions have found possible application directions in their own industries.
One is because this thing is small enough, and the other reason is that this thing is cheap enough!
It's small but not cheap enough, and it still can't be used everywhere because it's not affordable.
At this time, the leader of the 17th Machinery Department realized something that several other people who often dealt with computers did not feel.
"Zhendong, there are no similar chips abroad, right?"
Gao Zhendong was stunned for a moment: "Well, no."
According to the original history, 8008 still has more than ten years left, and there is absolutely no similar chip at this time.
The DJS-59 is probably not the first, and the DJS-60D is probably similar, but this thing is definitely a scorpion shit - the only one!
The leader of the 17th Machinery Department looked surprised: "No, that means this is a world-first thing, and you just threw it out like a cabbage?"
Gao Zhendong was a little confused: "What else?"
Do you still burn incense and bathe before worshiping heaven?
The leaders of other ministries and commissions also reacted. This thing is the first of its kind. No one in the world has heard of anyone who has the ability of Gao Zhendong to pack an entire computer into such a small number of chips.
They looked at Gao Zhendong holding on to the two pieces as if they were broken pieces of iron, and suddenly felt that their whole hearts were not in good condition.
"Put this thing away for me! Be careful not to drop it." The leader of the National Defense Work Committee looked at the two trembling chips in Gao Zhendong's hand.
Gao Zhendong smiled when he heard this and said: "Don't worry, there are plenty of these things."
After saying that, he opened a drawer and found a lot inside.
"I asked 1274 to make about a hundred pieces for each of them at one time, so I'm not afraid if they break."
Now, several leaders finally knew where Gao Zhendong had the confidence to say this thing was cheap.
There is only one prototype of DJS-59/60D each.
As for the core part of this thing, a casual experiment can cost hundreds of dollars. Looking at the circuit board in the chassis, it is also very simple.
Listening to Gao Zhendong's introduction, it is impossible to make just one wafer. A wafer costs from thirty to fifty!
Don’t think it’s too much. If you don’t have enough, you can’t do it. It’s a waste.
"How many lithography machines did 1274 open for you?" asked the leader of the 12th Machinery Department.
Gao Zhendong smiled: "They opened one for such a small amount. Other lithography products are still producing the SZ61 series. The lithography itself does not take much time. For lithography machines, complex masks and simple The masks are all the same, just like taking pictures. No matter how complicated the composition is, for the camera it is just a matter of pressing the shutter button. ”
Although Gao Zhendong said it simply, as if this thing is not very troublesome and there is really no need to make a big deal about it.
However, several leaders still felt that it was a waste. No matter what, this thing would have to be released at a conference, right?
Then this kid was pushed out just like he was talking about buying vegetables at the vegetable market.
The leader of the 12th Machinery Department lamented: "Zhendong, I know you don't take personal honor seriously, but this is not a personal honor, this is a collective honor, a national honor. It's too childish and too sloppy."
< br>
It is the first in the world, and it is in the high-tech field. It is not the kind of unreliable first. In any case, it is worthy of national honor.
The leader of the 17th Aircraft Department advised him: "Okay, it's better than the last DJS-59."
Having said this, the two of them remembered that when DJS-59 came out, the first person to see it was the cripple from the third rolling mill. They had no prejudice against cripples, mainly because the cripple also falsely accused Gao Zhendong...
The two of them suddenly felt even worse.
Gao Zhendong felt like an idiot, unable to keep up with their rhythm at all: "Then...how about I put it back and you pretend you don't know?"
"Forget it, it's a grand event with a few of us here." The leader of the National Defense Working Committee stopped Gao Zhendong's outrageous suggestion and immediately took the lead.
"The little chip is so weird,
If you are weak and strong, you can count quickly.
Cheap and beautiful,
Absolutely no takeout! "When Gao Zhendong heard this, his face turned red. Okay, okay, I know from this poem that you are in such a good mood! And it is extremely good, otherwise you would never be able to write at this level. Come.
It was obvious that the other leaders had already heard of his move, and they couldn't stand upright with laughter.
After laughing for a while, they gradually came out of their first encounter with the CPU.
"Zhendong, please formally introduce these two treasures. I was surprised just now and don't know much about these two things."
Gao Zhendong nodded and raised the chip in his right hand: "I named this chip the central processing unit..."
Gao Zhendong gave a general introduction to the composition and functions of the CPU. As for the English name of the CPU, he did not mention what the English name should be. Let foreigners have a headache when translating, and I will not take care of it.
Even though they had just known that this small processor completed most of the functions of the huge DJS-59 cabinet, several ministry leaders listened to Gao Zhendong’s introduction and looked at the comparison of the two things, and still felt that this Things are really amazing.
"As for this piece, I call it random access memory. The capacity of this piece is the same as the capacity of the four circuit boards in the DSJ-59." Gao Zhendong raised the RAM chip in his left hand.
I just thought that the functions were equivalent, but I didn't expect that the capacities were actually the same. Look at the four half-meter-square circuit boards, and then look at the small piece of a few centimeters square in Gao Zhendong's hand. For a moment, they didn't know what to send. What an exclamation.
Gao Zhendong brought over another assembled motherboard. The motherboard was no longer in the chassis. Only then did the leaders see what it looked like. It was a rectangular circuit board, no more than 20cm long, with 4 smaller circuit boards inserted on it. .
The two chips that Gao Zhendong held just now were inserted into it. In addition to these two special chips that can be seen at a glance, there are some other integrated circuits on the circuit board. It seems that they are mainly SZ61 series. 's film.
Gao Zhendong introduced with a smile: "This circuit board, I call it the motherboard, provides the necessary working environment for the central processor and random access memory. If a simple central processor and random access memory cannot become a complete computer, then This little thing is already a complete computer, the kind of computer I just mentioned.”
Gao Zhendong said and pointed to the two big guys next to him: "Thanks to the fact that they were born under the same architecture and use the same instruction set. Even structurally speaking, this central processor and DJS -59 is completely consistent, so all existing software can run on it without any modification, which is extremely beneficial for the utilization of our existing software.”
Amidst the admiration of all the leaders, Gao Zhendong is still not completely satisfied: "It is a pity that the external memory has not reached the state I planned, and there are still some defects in use. But this problem is not big, I have organized our factory Comrades from the Institute of Computer Science and the Beijing Watch Factory are working on 15-centimeter disk equipment, and the results should be available soon.”
"Beijing Watch Factory? From the 11th Machinery Department?" The leader of the 12th Machinery Department looked puzzled, "Can this thing be related to a watch?"
Gao Zhendong smiled: "Hey, it's really related. They have their own unique skills."
The National Defense Work Committee did not take the "flaws" mentioned by Gao Zhendong to heart at all: "Hurry up and finalize this machine. Once it is finalized, it will be easy for me to use."
Unexpectedly, Gao Zhendong shook his head.
"The second step to finalizing this machine is to finalize these two chips first. In fact, this machine is not important at all. What is important is these two chips. Careful units can modify the circuit on their own after understanding these two chips. , combine functions to create a computer that better meets their requirements. ”
"You mean, building a computer doesn't require too much professional knowledge?" The leader of the National Defense Work Committee frowned.
Gao Zhendong smiled and nodded: "Yes, as long as you can get the chip, building a computer will become a very simple matter. Just copy this motherboard and get some logic circuits with the same function as the SZ61 on the board. . However, there are two sides to the matter, and the reverse is also true.”
There is quite a bit of meaning in this statement.
No matter how large the scale of those machine builders in the previous life was, they were still not very technologically advanced.
The leader of the National Defense Work Committee relaxed his brows and said, "I understand. As long as you can't get these two chips, especially this central processor, then you can copy them however you want, and it's of no use."
No wonder he said that this thing is not afraid of others copying it. The core thing is blocked by his production technology. Even if the other things are left there for you to copy, you will not get any results.
"Hey, Zhendong, what you did is very difficult for me to handle with a bunch of DJS-59s and 60Ds." The leader of the 12th Machinery Department couldn't put it down while touching the circuit board on the table and said The trouble of being so good even though it's so cheap.
This thing is so good that no one is willing to keep these old machines, especially the DJS-59, even for reasons of saving and recycling, because compared to this little thing in their hands, this thing is really too Power consumption.
DJS-59: When I was just born, didn’t you praise me for saving electricity?
Therefore, happiness comes from comparison.
Moreover, everyone knows that in terms of reliability, this new machine absolutely beats the DJS-59. The failure rate of tens of thousands of components is not comparable to the failure rate of hundreds of components.
To be honest, everyone was surprised at how Gao Zhendong could ensure the reliability of that big guy within the usable range from the design.
Regarding his arrogance, Gao Zhendong has not yet said anything, and the Defense Working Committee has given up.
"That's nonsense. Otherwise, I'll solve the problem for you. I'll pay for the disassembly and assembly fees and shipping costs. You give me all the DJS-59 and 60D you have."
When Gao Zhendong heard this, he said, "Hey, the leader can do it. He even learned "50 free shipping to relieve your worries".
