Chapter 653 This is really a computer
Is this a computer?
Is this a computer?
Gao Zhendong smiled when he saw the expressions on the faces of a group of ministry leaders saying "This is eight years old?!".
"Yes, this is a computer!"
A group of ministry leaders rubbed their eyes in unison, and the leader of the 12th Machinery Department even walked up and stretched out his hand to make a few gestures.
They have all seen computers, including the smallest DJS-60D. Even Gao Zhendong designed it from the beginning to be divided and stacked according to 25*25, but no matter how stacked, the computer composed of two 50*50cm boards, It’s impossible to stuff it into this box that looks to be 20cm*20cm*5cm at most!
This box is smaller than the ordinary M-ATX desktop case that Gao Zhendong used in his previous life, and is close to the size of an ITX case.
The reason is quite simple. This computer has not considered expansion cards for the time being! Mainly expand peripherals through serial and parallel ports. In this way, all the space for the expansion card is saved, and there is no need for heat dissipation. The highest components on the board are the few 0.5K memory sticks, which are naturally not too big.
In fact, like the early Apple II, a keyboard-sized integrated chassis can be installed, and that's how it came about.
Not to mention that they thought it was small, even when people during Gao Zhendong's time travel saw this thing, they would only say it was weak in performance, but there was nothing to complain about in terms of size, it was really not that big.
"This...this..."
The leaders of the ministries and commissions now realized that this thing is the treasure that Gao Zhendong is going to present today!
Compared with others, what is a computer of this size if not a treasure?
The leader of the 12th Machinery Department looked at Gao Zhendong: "Is this a simplified version of DJS-60D?"
It can only be a simplified version, otherwise it would be impossible to fit it in.
Other leaders have similar ideas. After all, Gao Zhendong has already played this skill once. DJS-60D is a simplified version of DJS-59, but this time, he has implemented it to the extreme.
Although there may be a loss in performance, sometimes, being able to fit 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 2.5 times faster than DJS-59."
No, do you want to revise and revise what you said? It's so small, but it's a full version? Is the performance even stronger?
Seeing the "Don't brag" expressions on the leaders' faces, Gao Zhendong explained: "This computer is an integrated circuit, and its working frequency can be relatively high, starting at 2.5MHz, which is 2.5 times that of DJS-59 above. And because of the integrated circuit used, there are enough transistors for the realization of functions, so unlike DJS-60D which is simplified on the basis of 59, this is a full-featured integrated circuit implementation of DJS-59. ”
< br>
No, I was a little confused. The leader of the National Defense Work Committee asked: "I remember that your DJS-60D was implemented using integrated circuits, right? It didn't reach this level."
Gao Zhendong smiled and said: "Unlike the 60D, all the computing and control functions of this computer are integrated into an integrated circuit."
"One piece?" Everyone was shocked by this fact. When Gao Zhendong first succeeded in the integrated circuit process, he said that a small chip can accommodate thousands of transistors, but that was just a description. It's not intuitive, they can't imagine it at all.
But now, the shock of technology is truly displayed before their eyes.
Gao Zhendong took out a CPU and a RAM and introduced them to the leaders.
"Dear leaders, inside this cabinet is the central processing part of the DJS-59, and most of its functions are implemented here."
After speaking, Gao Zhendong pointed to the CPU chip a few centimeters square in his hand.
"Inside this cabinet is the transistor memory part of the DJS-59. Every four circuit boards in this cabinet are integrated into such a RAM chip."
Gao Zhendong raised another chip of the same size in his hand.
Faced with the impact of technological development, everyone present was shocked to the point of being speechless.
They pointed to the two huge cabinets of DJS-59, and then pointed to the two chips in Gao Zhendong's hand.
If the size of the DJS-59 is just a full-size cabinet, it is already small and exquisite compared to the M-3 and 103. Now the DJS-59 is an out-and-out behemoth compared to these two chips. The size comparison is far more shocking than that between DJS-59 and M-3/103.
"This... how... is this... possible..." the leader of the 17th Machinery Department sighed.
It's not that I don't believe in Gao Zhendong's integrity and technology. After all, these two things have been proven long ago, Bang Hard!
But I don’t trust my senses. Did I hear that 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 think of the question that he had asked himself thousands of times in his mind again - how did this kid grow his head?
Fortunately, this is my comrade, so it's okay.
The leader of the 12th Machinery Department was the most familiar with this thing. He confirmed it again: "Comrade Zhendong, in other words, this small iron box is a machine with the same complete functions as DJS-59, but faster than it." A general-purpose computer more than 2.5 times faster? ”
The appearance of this thing let them know why Gao Zhendong suggested opening the outlet of the DJS-60D. Compared with this thing, it was like heaven and earth. There was no psychological burden on it for export.
DJS-60D: So love will disappear, right? A certain stealth fighter that was slowly passing by at an air show but no one paid any attention to: Yes, it really can.
Gao Zhendong nodded: "Yes, and it is cheaper than DJS-59 and 60D, much, much cheaper!"
After speaking, Gao Zhendong said a number that they couldn't believe.
For ordinary people, it is still a huge number, but for industrial and military uses and its capabilities, leaders feel that it is just like cabbage.
When a new technology is not a commodity, taking integrated circuits as an example, its cost depends on two things: technology generation and quantity.
Although the technology generation of integrated circuits far exceeds that of DJS-59 transistors, and the unit cost is much higher than that of transistors, the quantity is not small, not to mention the warehousing, transportation, manpower, man-hours, etc. behind them.
If other people still have huge R&D costs when doing this, then for Gao Zhendong, the R&D costs can be said to be compressed to the extreme.
Not to mention that we won’t allocate the R&D costs into the component prices. Even if we do, it won’t be much money.
In his previous life, Gao Zhendong used 51 microcontroller chips worth 1 yuan, and they were the kind with relatively rich internal resources. This is the reason.
This sentence made all the leaders' eyes shine. What does it mean to go against the will of heaven? This is called going against the will of heaven!
Gao Zhendong smiled and said: "This is cheap, so maybe ordinary people can't use it, but at least the scientific researchers who need to use it can still afford it."
Do you want to hear what nonsense you are talking about? Can the general public use it? No matter how optimistic a comrade is, he would not dare to say this. This is too much of a boast.
Several leaders leaned forward and said to Gao Zhendong: "Come on, come on, run two programs and see."
There is no way, among the people present, he is the youngest and the most familiar with computers.
Gao Zhendong followed his example, sat down on the chair, and started it skillfully...
- Stack bricks.
Then a group of leaders watched Gao Zhendong play a whole game while the computer beeped, until the falling blocks exceeded Gao Zhendong's limit.
A group of people stared at each other, but they couldn't stop it. They were testing a new type of computer. Be serious!
Regardless of whether this test is serious or not, it at least proves that this thing can really work.
Gao Zhendong took out the program that tested the speed of floating point calculations and ran it again. Compared with the hardware multiplier, the results were still ugly, but compared with the DJS-60D, it was a leap forward.
"The time consumption is really only a little more than one third, what a speed! What a volume!"
The leader of the 12th Machinery Department reached out and touched the chassis with an extremely intoxicated expression on his face: "Small! Too small! Great!"
The leader of the National Defense Working Committee's eyes flashed. What he was thinking was, since this thing is so cheap and so small, then...hehe, hahahaha. He couldn't help but laugh inwardly.
Unlike them, who had to consider many things, the leader of the 17th Machinery Department had a simple idea: "This thing comes from us."
The leader of the National Defense Work Committee looked at this thing and said: "This thing can't be exported, can it?"
It seems that he was scared by the Ministry of Foreign Commerce. Gao Zhendong smiled and said: "You decide the export. The Gallic Chicken is there. Because of the cooperative software, a batch of them will probably go there. In fact, I am not afraid of this thing. If you want to copy it, it is better than DJS." -59 and 60D are much more difficult.”
If those two want to achieve the same function and performance, they can just copy the circuit. But for this thing, copying the circuit board is useless. They have to copy the circuit inside the chip, but the circuit inside the chip is not that good. Copied.
It’s not that it can’t be copied. With the 10 micron process, you can see it clearly with a microscope, but there is a huge difference between being able to see it clearly and being able to create it.
The Defense Works Committee and the 12th Machinery Department knew about the Gallic Chicken and were a little confused.
"For Chicken Gallic, the promised speed is ten times that of DJS-59, but this is still not achieved, right?"
Gao Zhendong said nothing and smiled without saying a word.
Hey, this kid also plays riddles, but since he wants to play riddles, he always has his own considerations, and several ministry leaders don't care.
"Zhendong, if this thing is really as cheap as you say, then the current software doesn't seem to be enough." The leader of the 12th Machinery Department is very knowledgeable. He is doing this after all.
Gao Zhendong nodded: "I have considered this. At the same time, I have to rely on the efforts of the comrades in the computing institute."
In future terms, this is called the hardware being built, but a killer application is still needed.
Hearing this, the leader of the National Defense Work Committee laughed: "You are overthinking it. Believe it or not, after a while, your 1274 factory's little production capacity will be eaten up as much as you have, and you don't need anything new." Software.”
The National Defense Work Committee still has a rough idea of the production capacity of the 1274 factory. It is definitely faster to produce this chip than DJS-59/60D, but it doesn't matter how big it is.
