Military Industry of Great Powers: Build the Strongest Flanker

After walking out of the door and walking down a path, the brick factory-like building you saw was the testing workshop.

Entering the workshop, you can see a lot of messy electronic equipment at first glance. In the direction Zhao Guoqing is pointing, a chip is inserted into the base. Dozens of messy wires lead out from under the base to connect the surrounding equipment and electronic circuits. superior.

Including Mu Hu, a large group of people looked at the chip again and again.

"This is a 16-bit programmable chip that integrates nearly 8,000 transistors. It is completely designed by us and manufactured by Qingda Microelectronics. It has a frequency of 5Mhz and can perform 80,000 integer operations per second and 30,000 floating point calculations per second. , can perform matrices, mathematical functions, and up to fourth-order integral calculations..."

Meng Fanxing frowned slightly, eighty thousand times? Thirty thousand times?

"I remember that the 80286 microprocessor only has so many integer operations and floating point calculations. They have 130,000 transistors, and you have 7,000 transistors. Mr. Zhao, are the data confirmed?"

Meng Fanxing was very suspicious. He looked at Zhao Guoqing and thought to himself, young man, I know you are capable, but bragging is not allowed!

Zhao Guoqing shook his head. There are two types of people he likes to deal with most in the world. One is those who don't understand anything and they trust you, and the other are those who understand very well and you can talk to them.

What I fear the most is a kind of person. Say he doesn’t understand. Say he knows something. Say he understands. That’s half a bucket of water. He stares at a few indicators all day long. Hey!

"Director Meng, 80286 is a microcomputer central processing unit. It needs to handle not only scientific calculations, but also multimedia processing, input and output, storage, peripheral management, involving complex x86 instruction sets, and the chip you see now, it Only responsible for scientific calculations!"

An entry-level GPU computing card has integer floating-point computing capabilities dozens of times higher than the top CPU of the same period. Can this be said to be that the GPU is more advanced than the CPU? It’s not the same thing at all!

Liu Qing said on the side: "I remember that there was a scientific computer installed on the ocean-going three-survey ship. Its performance can't keep up with this!"

Zhao Guoqing nodded and said: "This chip can basically meet the computing tasks on the three-way ocean survey ship!"

"..."

Director Liu Qing turned to look at Zhao Guoqing and said, "General Zhao, do you think this chip can be put on board?"

"We need to overcome the related ADC and DAC chips. The corresponding data format and transmission standard are based on the 1553B standard!"

“Isn’t the project huge?”

"Theoretically, it's similar to the modification project of Monster Snake III!"

"..."

Muhu held his breath, and looked closer at the dark thing in front of him. It was encapsulated in epoxy resin and looked very rough, so he simply protected it. The chips at the back were all encapsulated with ceramics, and a large pure copper plate could be covered on them. heat sink.

In fact, 5Mhz is far from reaching the limit of this chip. You can see that the heat dissipation on it does not even use a fan. It is limited by the bus frequency, and its frequency limit cannot exceed the bus frequency.

If a separate chip crystal oscillator is used and the bus is processed using frequency doubling technology, the frequency can be doubled or tripled. Of course, integrating the crystal oscillator semiconductor into the chip is also a major test for Qingda Microelectronics.

Of course, technological progress does not happen overnight. The current performance can basically meet the requirements. The function of radar cannot be improved by just one computing chip.

Mu Hu looked at it for a long time, his eyes were very excited and full of doubts.

"So, what is this chip used for?"

Okay, it took me a long time to introduce the performance, but I didn’t even introduce how to use it.

"It can be said that this chip is the brain of this phased array radar. After the data received by the radar is sampled by the ADC chip, all are sent to this chip for processing and calculation. Instructions are sent according to the program and transmitted to the radar through the DAC chip to track the target. , or give instructions to the weapon system to lock or attack..."

The more Zhao Guoqing spoke, the brighter Muhu's eyes became.

"So, medium-range radar guidance is not a problem. Do we have a one/two-way data link?"

After Mu Hu finished speaking, he looked at Zhao Guoqing with sharp eyes.

Zhao Guoqing was also surprised that Muhu was not as careless as he seemed. In fact, in the National Day images, his understanding of Muhu came from the Internet. In the memories of many people, they said that Muhu was as meticulous as silk and had a deep understanding of the international aviation industry. Knowing the development well, it is not surprising to hear him ask about the data link now.

"Leaders, please take a look at this..."

Zhao Guoqing showed them the system diagram, pointed to a place on the drawing and said: "The radar has reserved three parallel interfaces. The data transmission interface can be connected to the computer through a parallel bus. We have designed a data communicator that meets NATO standards. I think we For security reasons, the country will definitely need its own data link standard, and by then it will also be possible to access the computer through a parallel interface!"

The introduction of the 1553B bus standard will definitely have a profound impact on China's military industry. From these corners, we can see that advanced standards can save a lot of things.

"The auxiliary computing chip is sixteen-bit, but our bus is designed according to the thirty-two-bit standard. If we create better chips in the future, we can directly upgrade the microcode and replace it with the latest processor, corresponding ADC, After the performance of the DAC chip is improved, the sampling rate and bandwidth are enhanced. At that time, characteristic values ​​can be calculated through a large amount of data to determine what kind of aircraft it is. The influence of interfering radar waves can also be removed through numerical calculations, significantly improving radar performance."

…

A long silence...

These introductions have exceeded the scope of leaders’ understanding!

Anyway, it is very powerful, and it can be upgraded to be even more powerful in the future.

Mu Hu took a long breath and said, "General Master Zhao, you are very thoughtful!"

I couldn’t believe it, but I couldn’t help but look forward to the completion of this project.

Liu Qing looked at Mu Hu's troubled expression and thought of himself. Wasn't he the same way about the light-emitting semiconductor project? I couldn’t believe it could be done, but also thought what if it could be done?

He looked at Zhao Guoqing again. The young man in front of him had done so many earth-shattering things. He had never fired a blank cannon yet!

Director Liu Qing smiled and said, "How is the progress of the project? Can it be completed successfully?"

Zhao Guoqing nodded. He made a six-month completion plan. The most complicated ones were the chips and software. Although they were rushed, he could make circuits within 10,000 transistors by hand. As for the software, Zhao Guoqing There are also quite a few.

The official completion time of the project was determined by Tu Jinda, which was two years, but even if it was two years, the speed was already very fast.

Mr. Tu’s original words were: “The research on the 204 monopulse radar started in the 1960s, and the demonstration was passed the year before last. If you dare to claim that the phased array radar will be completed in half a year, I think the General Staff of the Science and Technology Commission must think that we If we are firing off cannons, we might even withdraw our funds!”

Teacher Xiao Zhao doesn’t believe in this evil.

I remembered what Tu Jinda said. The members of the inspection team to the United States all coveted the castrated pulse Doppler radar installed on the F16. As for the phased array radar, the United States has never thought of selling it.

Some people laughed at themselves and said that this time we are country bumpkins entering the city, and everything we see is good.

It is said that I have been poor for a long time and my eyelids have become shallow.

What if the poor wear a gold belt? It’s time for something super shocking!
