Chapter 653 This is really a computer

Is this a computer?
Is this a computer?

Gao Zhendong laughed when he saw the expressions of “This is eight years old?!.gif” on the faces of a group of ministry leaders.

“Yes, this is a computer!”

A group of department leaders rubbed their eyes at the same time, and the leader of the 12th Ministry of Machine Building even walked up and gestured a few times with his hands.

They had all seen computers, including the smallest DJS-60D. Even though Gao Zhendong had designed it to be stacked in 25*25 sections from the beginning, no matter how it was stacked, the computer consisting of two 50*50cm boards could not be stuffed into this box that looked to be at most 20cm*20cm*5cm!

This box is smaller than Gao Zhendong’s ordinary M-ATX desktop case in his previous life, and is close to the size of an ITX case.

The reason is simple. For this computer, expansion cards are not considered for the time being! The peripherals are mainly expanded through the serial and parallel ports. In this way, the space for expansion cards is completely saved, and there is no need for heat dissipation. The tallest components on the board are those 0.5K memory sticks, which are naturally not too big.

In fact, the early Apple II could be housed in an integrated keyboard case the size of a keyboard. That’s how it came about.

Not to mention that they think it's small, even if the people who traveled through time with Gao Zhendong saw this thing, they would only say that its performance is weak, but its size is impeccable and it is really not big.

"This this……"

The leaders of various ministries and commissions now realized that this was the treasure that Gao Zhendong was going to present today!
Compared with other computers, a computer of this size is nothing if not a treasure.
The leader of the 60th Ministry of Machinery looked at Gao Zhendong and asked, "Is this a simplified version of the DJS-D?"

It can only be a simplified version, otherwise it wouldn't fit in.

Other leaders had similar ideas. After all, Gao Zhendong had already tried this trick once. DJS-60D was a simplified version of DJS-59, but this time, he took it to the extreme.

Although there may be a loss in performance, sometimes being able to squeeze it in is the most important thing.

But Gao Zhendong's answer was beyond everyone's expectations.

"No, this is the full version of DJS-59, which is more than 59 times faster than DJS-2.5."

No, do you want to modify your words? It's so small, but it's become a complete version? The performance is even stronger?

Seeing the leaders' expressions of "don't brag", Gao Zhendong explained: "This computer is an integrated circuit. Its operating frequency can be relatively high, starting at 2.5MHz, which is more than 59 times that of DJS-2.5. And because it uses integrated circuits, there are enough transistors to realize the functions. So unlike the DJS-60D which is simplified on the basis of 59, this is an integrated circuit implementation of the full-function DJS-59."

No, I was a little confused. The leader of the Defense Work Committee asked, "I remember your DJS-60D was implemented with integrated circuits, right? It didn't reach this level."

Gao Zhendong smiled and said, "Unlike the 60D, this computer has all the calculation and control functions built into one integrated circuit."

"One chip?" Everyone was shocked by this fact. When Gao Zhendong first succeeded in the integrated circuit technology, he said that a small chip could accommodate thousands of transistors. But that was just a description, not intuitive, and they couldn't imagine it at all.

And now, the shock of technology is truly revealed before their eyes.

Gao Zhendong took out a CPU and a RAM and introduced them to the leaders.

"Leaders, inside this cabinet is the central processing unit of the DJS-59. Most of its functions are implemented in here."

After saying that, Gao Zhendong pointed to the CPU chip that was several centimeters square in his hand.

"And inside this cabinet is the transistor memory part of the DJS-59. Every four circuit boards here are integrated into a RAM chip like this."

Gao Zhendong held up another chip of the same size in his hand.

Facing the impact of technological development, everyone present was shocked and speechless.

They pointed to the two huge cabinets of DJS-59 and then to the two chips in Gao Zhendong's hand.

If the appearance of the DJS-59, which is only the size of a full-size cabinet, is already small and exquisite compared to the M-3 and 103, then now the DJS-59 is an absolute behemoth compared to these two chips. The size comparison is far more shocking than that between the DJS-59 and the M-3/103.

“This…this…how is it possible…” the leader of the 17th Ministry of Machine Building sighed.

It’s not that I don’t believe in Gao Zhendong’s integrity and skills. After all, these two things have been proven long ago, solid!

But don’t trust your own senses. Did I hear you right?

Gao Zhendong smiled and said, "Leader, this is true."

Everyone looked at Gao Zhendong who had a bright smile on his face, and couldn't help but once again think of the question they had asked themselves thousands of times - what's wrong with this kid's head?

Fortunately, this is my comrade, so it’s okay.

The leader of the 59th Ministry of Machine Building was the most familiar with this thing. He confirmed it again: "Comrade Zhendong, in other words, this small tin box is a general-purpose computer with the same complete functions as the DJS-2.5, but times faster than it?"

The appearance of this thing made them understand why Gao Zhendong suggested to open up the export of DJS-60D. Compared with this thing, that thing is simply a world of difference, and there is no psychological burden in exporting it.

DJS-60D: So love can fade away, right? A stealth fighter jet that slowly glides past an air show but no one cares about it: Yes, it really can.

Gao Zhendong nodded: "Yes, and it is cheaper than DJS-59 and 60D, much cheaper!"

After saying that, Gao Zhendong said a number that they all couldn't believe.

For ordinary people, it is still a huge number, but for industrial and military uses, and its capabilities, leaders feel it is as cheap as cabbage.

When new technology is not a commodity, taking integrated circuits as an example, its cost depends on two things: technology generation and quantity.

Although the technological generation of integrated circuits far exceeds that of the DJS-59 transistors, and the unit cost is much higher than that of transistors, the quantity saved is not a small amount, not to mention the warehousing, transportation, manpower, working hours, etc. behind it.

If other people do this, there will be huge R&D costs, but for Gao Zhendong, the R&D costs can be said to be compressed to the extreme.

Not to mention that we won’t include the R&D costs in the component prices. Even if we do, it won’t be much money.

This is the reason why Gao Zhendong used a 1-dollar 51 single-chip microcomputer in his previous life, and it was the kind with relatively rich internal resources.

This sentence made all the leaders' eyes light up. What is the meaning of going against the will of heaven? This is going against the will of heaven!

Gao Zhendong smiled and said, "This is cheap. Maybe ordinary people can't use it, but at least scientific researchers who need it can still afford it."

Do you want to hear what nonsense you are talking about? Ordinary people are using it? Even the most optimistic comrades would not dare to say so, this is too much exaggeration.

Several leaders approached Gao Zhendong and said, "Come on, let's run two programs and see."

There was no way. Among the people present, he was the youngest and the most familiar with computers.

Gao Zhendong followed suit, sat on the chair, and started the machine skillfully...

——Stacking bricks.

Then a group of leaders watched Gao Zhendong play a whole game amid the beeping sound of the computer, until the falling blocks exceeded Gao Zhendong's limit.

A group of people stared at each other, but they couldn't even stop the test. They were testing a new type of computer, so they had to be serious!
Regardless of whether this test is legitimate or not, at least it proves that this thing really works.

Gao Zhendong took out the program for testing floating-point operation speed and ran it again. Compared with the hardware multiplier, the result was still ugly, but compared with DJS-60D, it was a leap forward.

"It really only takes a little more than one-third of the time. Such speed! Such volume!"

The leader of the 12th Ministry of Machine Building reached out and touched the case, his face filled with ecstasy: "Small! Too small! Great!"

The leader of the Defense Work Committee had a gleam in his eyes. He was thinking, since this thing is so cheap and so small, then... Hehe, hahahaha. He couldn't help laughing in his heart.

Unlike them, who had to consider many things, the leader of the 17th Ministry of Machinery had a simple idea: "This thing is made here."

The leader of the Defense Work Committee looked at this thing and blurted out, "Is this thing not going to be exported?"

It seems that the Ministry of Foreign Trade has frightened them. Gao Zhendong said with a smile: "You decide on the export. As for the Gallic Chicken, they will probably send a batch of them because of the cooperative software. In fact, this thing is not to be feared. It is much more difficult to copy than DJS-59 and 60D."

If the two want to achieve the same functions and performance, they can just copy the circuit directly. However, copying the circuit board is useless. They have to copy the circuit inside the chip. But the circuit inside the chip is not so easy to copy.

It's not that it can't be copied. The 10-micron process can be seen clearly with a microscope. However, there is a huge difference between being able to see clearly and being able to make it.

The Defense Work Committee and the 12th Ministry of Machine Building knew about the Gallic Rooster incident and were somewhat puzzled.

"For the Gallic chickens, they promised to be ten times faster than the DJS-59. Is that not possible yet?"

Gao Zhendong said nothing, just smiled.

Hey, this kid is still playing charades. But since he is playing charades, he must have his own considerations, and several leaders of ministries and commissions don't take it seriously.

“Zhendong, if this thing is really as cheap as you said, then the current software seems to be insufficient.” The leader of the 12th Ministry of Machine Building knew everything, after all, he was in charge of this.

Gao Zhendong nodded: "I have considered this. At the same time, it depends on the efforts of the comrades in the computing institute."

In later terms, this is called the hardware has been made, but a killer application is still needed.

Hearing this, the leader of the Defense Work Committee laughed and said, "You are overthinking this. Believe it or not, after a period of time, the production capacity of your 1274 factory will be consumed as much as you have, and you won't need any new software."

The Defense Work Committee has a rough idea of ​​the production capacity of Factory 1274. The production of this chip is definitely faster than that of DJS-59/60D, but it is not that large.
