Chapter 767 The Seed of Automation
The young men no longer suppressed their emotions and expressed their feelings freely.

Although the core part was completed long ago by Chief Engineer Gao, the actual on-chip structure was designed by them, which required a strong foundation. If they had not had the experience in the design of the SZ61 series chips in the early days, I believe it would not have been so smooth.

Looking at this batch of seeds, Gao Zhendong was in a very good mood.

Although they are not much older than them, and even due to some special reasons, there are some who are slightly older than Gao Zhendong, but on this road, there is no doubt that they are all "young people" and the seeds of this industry.

Seeing that their emotions had been expressed, he said to the guys in charge of organization and coordination, "Test it again, pay attention to testing the upper frequency limit to see if it can meet the design requirements. At the same time, grasp the upper frequency limit. If there is no problem, transfer this batch to high and low temperature testing and baking."

What to bake? For those who have never experienced DIY, this term is a bit new.

Seeing that they were a little confused about this, Gao Zhendong explained the meaning of the word. After all, this was the first time for them to design and test integrated circuits of this scale. If it were comrades from the Institute of Computing, they would not have to do this.

After arranging these things, Gao Zhendong turned to the comrades from Factory 1274 and said, "Please notify the canteen of your factory and arrange a good meal for all the comrades participating in the test, including those from your factory, to celebrate."

The classmates all laughed. Hey, this is Chief Engineer Gao’s classic arrangement. But then again, the reason why classics are repeated countless times is that they really work.

For example, decades later, if a company can give out bonuses directly after completing a project without doing anything else, no one will complain that it is not innovative. In the words of Gao Zhendong, the simpler the company's bonus distribution conditions and algorithms are, the more likely the company's leaders are open-minded. The more complicated the bonus algorithm is and the more incomprehensible terms there are, the less likely they are to give you money.

A similar situation occurred again a few days later. This time, it was a general-purpose digital signal processor chip. Although its efficiency in performing algorithms such as FFT and convolution is not as good as that of specially optimized FFT processors and specialized signal processors such as convolution, its scope of application is much larger. At most, it can be multi-path parallel. For equipment that needs to perform a large number of similar operations, the cost issue is generally not a big consideration, at least there is no shortage of money for those chips.

However, when Gao Zhendong designed this thing, he retained the data bus that is common to C6108, which means that C6108 can exchange data with it and even directly control it to perform mathematical operations.

This usage will be very familiar to people who lived in the 80386 and 486 era decades later. Isn't this a math coprocessor? The 80387 and 80487 were only found in the most advanced computers at the time.

After completing these tasks, Gao Zhendong only made two follow-up work arrangements.

First, we will prepare and start the finalization and mass production work for these two devices, and prepare for finalization and mass production.

Secondly, expand the digital signal processor/mathematical coprocessor to 32 bits.

For the young comrades, the second task was a bit arduous, but when they thought about having Chief Engineer Gao standing behind them, they calmed down.
-
The 12th Ministry of Machine Building, the Defense Work Committee, as well as the Postal and Communications Committee and the 11th Ministry of Machine Building, which had relatively large demands for control equipment, all received Gao Zhendong's letter stating that a new computer component was to be released and introduced, which aroused their great interest.

In fact, it was originally for project acceptance, but no one could inspect Gao Zhendong. Acceptance was just a process, and the real work was to promote this thing.

As long as Gao Zhendong invites someone seriously and proactively, it must be a big deal. The things are definitely good things, and they are good things of great significance!
So the list of participants in the conference is really star-studded.

Gao Zhendong only invited technical personnel from relevant ministries and commissions to attend the meeting, but it goes without saying that the Defense Work Committee and the 12th Ministry of Machine Building regarded Gao Zhendong as an internal staff member of their system. Even the Postal and Communications Committee, their leaders came. As soon as he entered the venue and saw Gao Zhendong, Gao Zhendong knew the reason.

"Comrade Zhendong, our switch is almost ready. Hahahaha, as the project leader, please take some time to go and take a look."

Gao Zhendong agreed readily. This thing is a typical technology-intensive equipment, which has both hardware and software, and also involves topology, especially space-division switches, so it is normal for the progress to be slow.

If the leaders of the Postal and Communications Commission knew what Gao Zhendong was thinking, they would probably regret coming to the meeting today. Okay, kid, you think this speed is too slow?

Seeing that everyone who should have come had arrived, Gao Zhendong announced the start of the meeting.

What made the leaders happy was that this time, the person responsible for the introduction and report was not Gao Zhendong himself. Gao Zhendong just sat in the first seat calmly, watching a young man from the Defense Work Committee make a report.

But what puzzled them was that the parameters of this so-called new IC were rather mediocre.

The bit width and main frequency are the same as C6108, 8 bits and 2.5MHz. There are 128 bytes of RAM on the chip, which is about the storage capacity of a C6110. There are two hardware timers, a serial port, some input and output ports, and multiple interrupt sources...

In short, listening to the introduction, this thing is probably just one C6108 + one C6110, and I can't hear any advantages at all.

Although the participants felt strange, they still listened patiently considering Gao Zhendong's past achievements. Comrade Zhendong had so many important achievements, so even if they wasted half a day with him, it would not be unacceptable.

After the report, there is the regular demonstration session.

Now, this thing looks more like C6108. Many demonstration programs are exactly the same, with basically no difference. But what’s interesting is that the young man who gave the report presentation showed more about the control capabilities.

It’s so luxurious to use C6108 for control.

As if he had seen through their doubts, Gao Zhendong stood up and walked to the side of the computer case. "Maybe all the leaders and experts are a little surprised that this thing is no different from the C6108. Actually, you are wrong. There are still differences. The internal registers and other parameters of this thing are lower than those of the C6108!"

You said this in a naughty way. The leaders of the Defense Work Committee and the 12th Ministry of Machine Building were a little amused. It seemed that Gao Zhendong had a child, and he started to act childishly too.

"But there is another difference between it and C6108!"

I know it! Once Gao Zhendong uses the word "but", it means that the matter is not trivial.

People in the meeting hall, while several young people who were reporting were smiling with a hint of mystery and admiration, Gao Zhendong reached out and picked up something from the table.

"In theory, that's all there is to it!"

Everyone looked closely and saw that Gao Zhendong had a circuit board in his hand that was only half the size of a palm. On it was a chip, a silver iron shell component, a button, a resistor and three capacitors.

This is actually the result of Gao Zhendong's design based on a peripheral circuit similar to the 51 single-chip microcomputer in his previous life. The silver component is a crystal oscillator, the button is the reset button, a resistor and a capacitor form a reset circuit, and there are two capacitors that work in conjunction with the crystal oscillator.

In fact, there are some peripheral circuits that are not here, such as power supply, display, keyboard, etc., but this minimum circuit can work normally as long as there is power.

The leader of the Defense Work Committee was the first to react. He had heard of this thing for a long time and had been thinking about it for a long time!
"Comrade Zhendong, what do you mean by this?" He confirmed again.

Read the error-free version at 69shuba! 6=9+shu_ba is the first to publish this novel.

Gao Zhendong smiled and said, "In theory, this small circuit board in my hand is a computer, a computer with a computing speed that is at least 59% faster than the DJS-50. Although it has no keyboard or display, it can work. As long as it is connected to an external memory, it can complete simple mathematical calculations, logical judgments, timing and fixed points, and has certain data collection and control output capabilities."

The main frequency of this thing is 2.5MHz, which is two or three times higher than the 59~0.6 of DJS-0.8. However, since some resources such as registers have been cut, the speed is not that much higher.

But even this is shocking enough.

Gao Zhendong's words completely stunned the unprepared people.

Just this thing that is half the size of your palm?

“Is this a computer?”

“Is this a complete computer?”

"how is this possible?"

"No... more than two years ago, a computer would have required a whole room to house it."

Everyone suppressed their excitement and looked carefully and greedily at the small circuit board in Gao Zhendong's hand. They couldn't help but be greedy. With this, there would be more possibilities in the areas they were responsible for.

For the sake of work, it's not shameful to be greedy.

"Is it expensive?" someone asked this question carefully.

Gao Zhendong smiled and shook his head: "Not much different from a piece of C6108."

It is not much different from a C6108, but it is different from using C6108 for simple control.

The former means that you only need to invest in one C6108, while the latter means investing in a whole set of DJS-61 specification computers. The difference between the two is huge.

As for external storage, they didn't care too much about it. They used firmware chips where the requirements were high, and used tapes and disks where the requirements were low. Those two things were very cheap!
The people who thought the most about this were the leaders and chief engineers of the 12th Ministry of Machine Building. They could imagine countless places where this thing could be used. The smaller the thing was, the easier it was to reinforce, the less impact the environment had on it, and the smaller the investment. In addition, this thing itself was cheap, so there were more places where it could be used.

Together with the leaders of the Defense Work Committee, they recalled the course Gao Zhendong taught at Beijing University of Technology.

——"Principles of Automatic Control"!
One hard and one soft, quietly, the seeds of automation have sprouted and are growing.

Comrade Zhendong's layout had already started a long time ago.
