Chapter 463: Cutting-edge products

Imperial City, Haidian District, south of Zhongguancun. There are many organs at the foot of the emperor.
Xiao Jinlang returned by plane. He was also picked up by a car and went directly to the Imperial Institute of Control Engineering.
The surrounding area is full of terrible scientific research institutions, and the sign hanging on it is ‘Chinese Academy of Sciences’. Armed police are on guard everywhere, and can't get in without relevant documents.
The name of 'Control Engineering Research Institute' sounds average, but many of the domestic satellites come from here. There are a large number of national and ministerial experts, and academicians are all in double digits.
" Daily" brand is not good here. After Xiao Jinlang followed in, he sat down in the reception room without any problems.
The electronic devices provided by Zhou Qingfeng and the cutting-edge cpu were handed over. Xiao Jinlang was tired for two or three days in a row, and he became sleepy when he was relaxed. He simply lay a few chairs in the reception room for a night.
After lying for several hours, Lao Xiaojue woke up with something on his body. It was a researcher in the institute who gave him a coat. Seeing him awake, the other laughed again: "Comrade Xiao, it's hard." Computer side :: /
Compared with Chen Mu's excitement at the machine tool factory, the researchers are more emotionally stable.
Lao Xiao sat up and said a few 'should', and asked casually, "Should I go back?"
"No rush, no rush, wait for a result first." The researcher is also middle-aged, looking older than Xiao. He poured a cup of hot water and asked with a smile: "Can you talk about the origin of this shipment?"
This is the end.
Lao Xiao and Chen Mu came back in a hurry and only reported the situation verbally. The paper report was not finished. He was also awake, sat upright, and probably talked about Zhou Qingfeng, who has returned from overseas, and his holy light.
"Oh, it's a patriotic overseas Chinese." The researcher's face bloomed with smile. "Very good, it's rare.
Electronic devices are still being tested and performance is unclear. But the 386ex is a general-purpose processor. We only received some news before that the United States is working on this model.
I didn't expect people to make it.
This is really the most advanced aerospace-grade on-board processor, and its performance is very powerful. It is extremely useful in attitude control and communication processing. "
When the researcher said this, he couldn't help sighing.
Because in 88 and 90 years, the rabbit launched two weather satellites 1a and 1b. Their launches have given China a large amount of earth weather data.
but
1a satellite is because the on-board components are contaminated, the processor did not resist under the strong solar radiation. The satellite's attitude was out of control and it hung up after only 39 days of work.
The 1b satellite is slightly better, but it only works for less than half a year, and the on-board processor suddenly fails and hangs up.
In terms of the average satellite's life span of at least three to five years, these two are typical early deaths.
Rabbit did not work for seven years until the launch of 'Fengyun-1c' in 1999. The satellite-borne cpu used was a 16-bit 80c86 with a main frequency of only 3 megabits and was imported at a high price.
'386ex' is already thirty-two.
It is a new millennium for Rabbit to truly break through the technological difficulties of the on-board processor.
Just to say, ‘Fengyun-1c’ was originally designed to have a life of two years and a seven-year extended service life.
When retired in 2007, the rabbit fired an anti-satellite missile from Xichang, and used the kinetic energy warhead to accurately destroy the meritorious satellite.
The North American Air Defense Command of the United States has detected this experiment, and in the media, slandered us for destroying world peace and destroying it. Can you do it?
But now, Rabbit's on-board processor is really bad. Basic semiconductor technology is not sloppy, and cutting-edge products are even blank.
At this time, the domestic spaceborne computer simply executes a certain programmed instruction and performs some simple tasks of attitude control, which can not do much work.
The first to get aerospace-grade chips was 772 of the Nineth Academy of Aerospace, which was not the key main control CPU, and it will not succeed until 2003.
Until 11 years, domestic aerospace-grade CPUs are launched as backups of imported CPUs. It is not until 15 years after the launch of the 'Beidou' Double Star that the domestic cpu is considered to carry the beam.
It's still 91 years old. Zhou Qingfeng took out the 386ex, and he was shocked by the Emperor Control Engineering Research Institute. He also thought that '386' was a low-end product, but he did not know that it was a proper high-tech product.
The powerful processor can process load data in real time, accept ground instructions, and manage control attitudes. It can greatly reduce the weight of the satellite.
Power supply, board lines, and peripherals can be simplified. Move the functions implemented by the circuit to the cpu.
In fact, the original name of the chip was 'Very Large Scale Integrated Circuit'. A '386ex' integrates hundreds of thousands of transistors. If these tubes are not integrated, the satellite will have to weigh hundreds of tons.
The original research staff can only design satellites around low-end processors such as 80c86. With high-end goods now, research ideas can be greatly broadened.
And the 386ex we got this time is not one or two, but we have given more than 20 samples. In addition to being used for ground testing, it can be used to produce a satellite.
After all, today's satellites are not mass-produced, and each one can be said to be customized.
Xiao Jinlang also said that Zhou Qingfeng could get more cutting-edge aerospace-grade processors. Different varieties and different performances have everything.
In addition to the cpu, there are aerospace-grade memory, high-performance batteries, high-gain antennas, data processing DSPs, converters, data buses, and transmitting devices.
Just sent a satellite directly.
The researchers in the institute became more and more excited, and took out pens to keep notes in their own small books. As he remembered, he asked repeatedly.
"Are all these things possible?"
"Can't believe it! These things are too cutting-edge."
"If Americans knew it, they would be furious."
"Oh, you shouldn't tell me this. Keep the privacy regulations in mind."
"Once the news leaks, this overseas comrade is in danger."
"Forget it, forget it, I won't ask. It must be protected."
"Let that comrade not keep thinking about doing good things, the more they do, the easier it will be to expose. The finer the water is, the better."
At the end of writing, the researcher stopped the pen and tore off all of his own records and the subsequent blank paper pages, and burned them off. "This information cannot be disclosed to outsiders and must be kept strictly confidential."
At this moment, there was a knock on the door outside the reception.
The young man in the office called out the middle-aged researcher. Xiao Jinlang watched a few whispers in their ears, and the middle-aged researcher even laughed and was overjoyed.
"Okay, two high-power gallium arsenide mos tubes have passed the test. The performance indicators are more than ten times higher than our existing products. They are small in size, light in weight and low in heat.
The 14 institutes in Nanjing are well informed, and the phone has been called to the ministries and commissions, asking them to make a batch of samples for them to make radar. Alas, they want to be beautiful. Do n’t even try to grab something in our hands. "
The middle-aged researcher wears glasses and a Swan suit in a sun suit, but at the end shows a bandit who laughs and curses freely.
Xiao Jinlang didn't feel a smile. Robbing funds, talents, equipment, and even everything that can be grabbed in the system is the normal state of healthy competition.
If the head of a hospital does not rob, the people below will feel that the boss is not motivated, and the leader will feel that his working attitude is not positive.
Speaking of this, middle-aged researcher Chao Jinlang asked: "Within a week, we will conduct a comprehensive test on this sample, and the report will be issued soon. I would like to ask now, when will the next batch of samples arrive? "
Xiao Jinlang smiled wryly, "Well, it should be fast!"
