Chapter 654: The World's First CPU (Today is five chapters, two chapters will be released first)

In fact, he was not the only one who thought of this. All the leaders of ministries and commissions had found possible application directions within their own industries.

One reason is that this thing is small enough, and another reason is that it is cheap enough!

It's just small but not cheap enough, and still can't be used everywhere because people can't afford it.

At this time, the leader of the 17th Ministry of Machine Building realized something, which the other people who often dealt with computers did not notice.

"Zhendong, there are no similar chips abroad, right?"

Gao Zhendong was stunned for a moment: "Well, no."

According to the original history, 8008 was still more than ten years away, and there was absolutely no similar chip at that time.

DJS-59 is probably not the first of its kind, DJS-60D probably has something similar, but this thing is absolutely like scorpion shit - unique!
The leader of the 17th Ministry of Machinery was surprised: "No, that is to say, this is a world-first thing, and you just threw it out like cabbage?"

Gao Zhendong was a little puzzled: "What else?"

Do you still need to burn incense, bathe, and offer sacrifices to heaven first?

Several other department leaders also reacted. This was a first of its kind. No one in the world had ever heard of Gao Zhendong's ability to squeeze an entire computer into such small chips.

They looked at Gao Zhendong holding the two pieces of paper as if they were a piece of broken iron, and suddenly they felt unwell.

"Please put this thing away for me! Be careful not to drop it." The leader of the Defense Work Committee looked at the two trembling chips in Gao Zhendong's hands.

Gao Zhendong smiled and said, "Don't worry, there are plenty of these."

After saying that, he opened a drawer and saw a huge pile of things inside.

"I asked 1274 to make about pieces for each at one time, so we don't have to worry if they break."

Now, several leaders finally understood where Gao Zhendong got the confidence from saying that this thing was cheap.

There is only one DJS-59/60D prototype each.

As for the core part of this thing, it costs hundreds of dollars to do a random experiment. Looking at the circuit board in the chassis, it is also very simple.

According to Gao Zhendong's introduction, it is impossible to make only one wafer, as one wafer requires at least thirty to fifty pieces!

Don’t complain that it’s too much. If it’s less, you can’t do it and it’s a waste.

"How many photolithography machines did 1274 run for you?" asked the leader of the th Ministry of Machine Building.

Gao Zhendong smiled: "For such a small quantity, they only opened one machine, while other lithography companies are still producing SZ61 series products. Lithography itself does not take much time. For lithography machines, complex masks and simple masks are almost the same, just like taking a photo. No matter how complex the composition is, for a camera, it is just a matter of pressing the shutter."

Although Gao Zhendong put it simply, it seemed as if this thing was not that troublesome and there was really no need to make a big fuss about it.

However, several leaders still felt that it was a waste. They thought that this thing should at least be released in a grand meeting, right?

Then this kid was pushed out just like he was chatting and buying vegetables in the market.

The leader of the 12th Ministry of Machine Building was heartbroken: "Zhendong, I know you don't take personal honor seriously, but this is not personal honor, this is collective honor, it is national honor, it is too frivolous, too sloppy."

It is a world first and in the field of high technology. It is not an unreliable first. In any case, it is worthy of national honor.

The leader of the 59th Ministry of Machinery advised him: "It's OK. It's better than the last time with DJS-."

At this point, they both remembered that when the DJS-59 was first released, the first person to see it was the lame man from the third rolling mill. They had no prejudice against the lame man, but the main reason was that the lame man had falsely accused Gao Zhendong...

The two of them suddenly felt even worse.

Gao Zhendong felt like an idiot, totally unable to keep up with their pace: "Then...how about I put it back and you guys pretend you don't know?"

"Forget it, forget it. With a few of us here, it can be considered grand." The leader of the Defense Work Committee stopped Gao Zhendong's outrageous suggestion and immediately improvised a poem.

"The little chip is really strange.
He is small in stature but strong in strength and can calculate quickly.

The price is low and the product is beautiful.
Definitely not to sell it outside! " Gao Zhendong's face turned red when he heard it. Okay, okay, from this poem, I know that you are in a really good mood! And it is the kind of extremely good mood, otherwise you can't write at this level.

It was obvious that the other leaders had heard about this trick of his and were laughing so hard that they couldn't straighten their backs.

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 just too surprised to know much about them."

Gao Zhendong nodded and raised the chip in his right hand: "I'll name this one the central processing unit..."

Gao Zhendong gave a general introduction to the composition and functions of the CPU. As for the English name of CPU, he did not mention it. Let the foreigners worry about the English name when translating it. I won’t help you.

Even though they already knew that this tiny processor completed most of the functions of the huge DJS-59 cabinet, several leaders of ministries and commissions still felt that this was amazing after listening to Gao Zhendong's introduction and looking at the comparison between the two things.

"As for this piece, I call it a random access memory. The capacity of this piece is the same as the capacity of the four circuit boards in DSJ-59." Gao Zhendong held up the RAM chip in his left hand.

Just now they thought that the functions were equivalent, but they didn't expect that the capacity was actually the same. Looking at the four half-meter square circuit boards, and then looking at the small piece of several centimeters square in Gao Zhendong's hand, they didn't know what to say for a moment.

Gao Zhendong brought over another assembled motherboard. The motherboard was no longer in the chassis. The leaders were able to see its appearance clearly. It was a rectangular circuit board, no more than 20 cm long, with four smaller circuit boards inserted on it.

The two chips that Gao Zhendong had in his hand just now were both inserted on 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, which seem to be mainly SZ61 series chips.

Gao Zhendong introduced with a smile: "This circuit board, I call it the motherboard, provides the necessary working environment for the central processing unit and random access memory. If the central processing unit and random access memory alone cannot be a complete computer, then this little thing is already a complete computer, the kind of computer I just mentioned."

Gao Zhendong said, pointing to the two big machines next to him: "Thanks to the fact that they are both born under the same architecture and use the same instruction set, even from a structural point of view, the central processor is completely consistent with the DJS-59, so all existing software basically does not need any modification to run on it, which is extremely beneficial for the use of our existing software."

Amid the praises of the leaders, Gao Zhendong was still not completely satisfied: "It's a pity that the external storage has not yet reached the state I planned, and there are still some defects in use. But this is not a big problem. I have organized comrades from our factory, the computing institute, and the Beijing Watch Factory to make 15 cm disk equipment, and there should be results soon."

"Beijing Watch Factory? From the 11th Ministry of Machinery?" The leader of the 12th Ministry of Machinery was full of confusion. "How can this thing be related to watches?"

Gao Zhendong smiled: "Hehe, it does have something to do with it. They have their own unique skills."

The Defense Work Committee didn't take Gao Zhendong's "defects" seriously at all: "Let's finalize this machine quickly. It will be easier for me to use it once it's finalized."

Unexpectedly, Gao Zhendong shook his head.

"Finalizing the machine is secondary. First, let's finalize the two chips. In fact, the machine itself is not important. What's important are the two chips. After a company has a thorough understanding of the two chips, it can modify the circuits and combine the functions to create a computer that better meets its requirements."

"You mean, building computers doesn't require too much professional knowledge?" The leader of the Defense Work Committee frowned.

Gao Zhendong smiled and nodded: "Yes, as long as we can get the chip, building a computer becomes a very simple matter. We just need to copy this motherboard and make some logic circuits with the same functions as the SZ61 on the board. However, there are two sides to every coin, and the same is true in reverse."

There is some profound meaning in this statement.

In the past, no matter how large the computer assemblers were, they did not have high technological content.

The leader of the Defense Work Committee relaxed his brows and understood. As long as they couldn't get these two chips, especially the central processing unit, it would be useless no matter how they copied.

No wonder he said that he was not afraid of others copying this thing. The core things were blocked by his production technology. Even if the other things were left there for you to copy, you would not be able to get any results.

"Oh, Zhendong, what you've done is really hard for me to handle with a bunch of DJS-59 and 60D in my hands." The leader of the th Ministry of Machine Building fondly touched the circuit board on the table and expressed his annoyance of getting a bargain.

This thing is so good that even for the sake of saving and reusing old machines, no one is willing to keep these old machines, especially the DJS-59, because compared with this little thing in hand, this thing consumes too much power.

DJS-59: When I was just born, didn’t you praise me for saving electricity?
So, happiness is created by comparison.

Moreover, it is obvious that this new machine absolutely beats the DJS-59 in terms of reliability. The failure rate of tens of thousands of components cannot be compared with the failure rate of dozens or hundreds of components.

To be honest, everyone was surprised at the time how Gao Zhendong alone was able to ensure that the reliability of that big thing was within the usable range from the design perspective.

Before Gao Zhendong could say anything about his arrogance, the Defense Work Committee was no longer happy.

"Nonsense, how about this, I'll solve the problem for you, I'll pay for the disassembly and shipping, and you just give me all the DJS-59 and 60D you have."

When Gao Zhendong heard this, he was like, wow, this leader is really good, he even learned the trick “50 free shipping to relieve your worries”.
