When it comes to chips, most people can only think of CPUs. In fact, in the professional military field, CPUs can only be considered part of them. DSP chips are specially used to process digital signals and can achieve the best results in professional fields.
DSP chips, which use Harvard structures with separate programs and data, have special hardware multipliers, widely use pipeline operations, and provide special DSP instructions, so that various digital signal processing algorithms can be quickly implemented and adapted to the needs of multi-scenario applications.
.
Simply put, the CPU can process digital signals, but it is not dedicated, so the processing speed is very slow. This is like a DVD movie, which can be decoded using a computer CPU, but this is software decoding and the speed is very slow.
, if placed in a special DVD machine, it is hardware decoding, and there are special chips inside, so it does the encoding and decoding of DVDs, and the efficiency will naturally be greatly improved.
Therefore, with the continuous advancement of technology, ordinary microprocessors have lower processing speeds and are unable to meet the high-speed real-time requirements of increasing information. DSP chips stand out, and after they come out, they will soon be in communication.
, radar, image, military, instruments, automation, signal processing and other fields have been widely used.
Because there are many use scenarios, the use of this chip is quite large. Therefore, they use this chip as a breakthrough point to make huge investments recover as soon as possible and achieve healthy development.
Tens of millions of investments are all major projects across the country. Wang Xiaoqiang knows that it is because of Qin Zhenhua that he can realize his dream. Otherwise, he would probably be in a state of decline and go to a foreign country to realize his dream.
It's right.
Listening to Wang Xiaoqiang introducing various parameters, Mr. Liang was moved: "If the quality of this chip can be guaranteed, our C801 missile? Looking forward to purchasing this chip to improve our seeker? At the same time, we will also put it into
It is introduced to the navy? Not to mention anything else? At present, our Hongqi-7 missile urgently needs such professional chips. In the command system of warships, this type of chip is also needed. Preliminary estimates: Within five years? We
At least you need to order thousands of these chips."
With the introduction of the Sea Rattlesnake missile from France, it has greatly accelerated its own self-development pace. The Hongqi-7 missile has now emerged. The second-generation missile destroyer of the Navy? This is the one that is planned to be equipped with.
Missile system.
This Sea Rattlesnake missile weapon is called the Tomsi combat system? It includes three parts: the Sea Rattlesnake missile system, the Tavitak tactical data processing system, and the Sea Tiger radar. Among them, the Tavitak tactical data processing system is the Tavitak tactical data processing system.
It serves the Sea Rattlesnake ship-air missile system and is the comprehensive data processing system of the Tomsi combat system. This system requires a large number of DSP chips as support.
At present, the first ship of the planned second-generation missile destroyer? I plan to install the original French goods on it directly, and then conduct self-development of the second ship? This Tomsi combat system is the focus of imitation? Now, it is finally solved.
The chip problem has been solved.
Besides? Not just a simple air defense missile subsystem? A new generation of destroyers? It is planned to adopt the domestic ZKJ-4B combat command system as the core of the entire ship's combat system. This combat command system also requires high-efficiency DSP chips.
To handle huge digital signals.
I originally thought I needed to import, but now, the domestic products finally got up. It's so great. When I think of this, Mr. Liang was full of excitement.
"We only ordered thousands of dollars within five years. Mr. Liang, you are too stingy." Qin Zhenhua said to Mr. Liang: "Our machine factory plans to purchase 100,000 yuan of such chips within five years.
”
"Why do you want so much?" Mr. Liang was puzzled.
"This kind of chip is needed in our tanks, fire control systems, sighting systems, and communication systems. We have predicted that a tank needs at least five such chips, as well as various armored vehicles." Qin Zhenhua
He said: "This kind of chip is also an industrial control chip. We need to improve our production lines and realize automated production, but we cannot do without these chips. The old leaders have said that we should have a longer vision and take bigger steps."
"What do you want in the communication system for this kind of chip?" Mr. Liang was a little curious. You said fire control, watching, these require DSP chips, I can still accept it. Why do you want this thing for tank radio stations?
"The noise inside the tank is very loud." Qin Zhenhua said: "Our tank hands can only rely on the throat sender to contact us. Now, there has been theoretical evidence that digital means can be used to eliminate it. Voice has a short-term stability.
The human ear is not sensitive to speech phase, so the frequency domain enhancement method of short-term spectral amplitude can be used, which requires a special DSP chip to calculate..."
Mr. Liang, who is professional in listening to these words, can't stand it anymore. Okay, don't show off. I know that you have a good hand in these aspects, so that's OK, right?
When electronic technology enters digital circuits, there are indeed many differences. Some advanced means can be used, which plays a very magical role. After the development of this circuit, the tank hand can just shout at the microphone at the mouth.
The noise is filtered directly, leaving only clear voices of shouting, and the combat effectiveness must be improved a lot.
(I remembered something for no reason. The unit where the hero of East China used to be in digital management. I was excited to hear that I thought I would equip everyone with a computer. Later I realized that the so-called digitalization means no matter what I do.
All of them have to count how many papers you have been awarded today, how many pages you have used to prepare a textbook, and even asked a few students to do work. This is called digital management. At that time, I was bleeding.)
"We have this technology in China?" asked Mr. Liang. At this time, he was embarrassed to suspect that Qin Zhenhua was bragging, so he could only ask: "Which unit is in?"
"Hongxing Electrical Factory." Qin Zhenhua said: "They have recruited several college students this year. These college students have mainly studied this topic. The general factory is very interested and has allocated funds for them to conduct research."
Hongxing Electrical Factory! The A Dou who couldn't help at the beginning was always lying on a machine factory to drink blood. Later, Qin Zhenhua merged the Hongxing Electrical Factory after bankruptcy. After reform, he finally regained his vitality. Now he knows how to study these things.
The new thing is coming, which makes Qin Zhenhua very pleased.
We cannot always follow others. We must also innovate and come up with things that belong to our own characteristics! Innovation ability is the most important.
