Military Industry of Great Powers: Build the Strongest Flanker.

Chapter 219 South China Sea...the enemy plane is coming

Liu Qing asked: "Compared with 486, how much better can the performance be?"

A month ago, Zhao Guoqing might have just announced in a low-key manner that it would be no problem to increase the performance by ten times.

Now, as the research and development of ARMv6 becomes more and more in-depth, the technical indicators become more and more specific, and this performance estimate becomes more and more clear.

The original frequency of 486 was only 25M Hz, and the newly released one was only 50M Hz. Not to mention the improvement of IPC, the design frequency of ARMv6 alone has reached 600M Hz, which is about 486 times better than the latest 12.

In addition, ARMv6 has 2000 million transistors, while 486 has only 120 million transistors. Can the performance be the same at the same frequency?

The 486 has only one floating point unit and one integer unit, while ARMv6 has sixteen floating point units and eight integer units.

If the performance of ARMv6 can be fully utilized, the IPC should be more than twelve times that of 486.

In other words, under one clock, ARMv6 can execute more than 12 instructions, while 486 can only execute one.

Of course, it is difficult to achieve an ideal state, because due to the characteristics of algorithms or actual computing tasks, it is difficult to exert 100% of CPU performance, but on average, half of the ability can be exerted.

Zhao Guoqing said embarrassedly: "The performance of our new computer can exceed the performance of the 486 computer by 60 times!"

"...Sixty times?" Director Liu was so surprised that he was speechless. He knew that Teacher Xiao Zhao never brags!

Director Liu said: "If it is really sixty times, wouldn't it be almost the same as a minicomputer?"

Zhao Guoqing nodded. Indeed, IBM's latest minicomputer has this performance and costs one million US dollars!

Director Liu asked: "How much is the approximate cost? Have you calculated it?"

Zhao Guoqing said: "If the research and development costs are not included, the whole machine will cost about five to six thousand yuan!"

"So cheap!" Director Liu finally understood what Teacher Xiao Zhao said before. If he let his hands and feet compete with the Americans, they would be beaten to pieces.

You must know that a 486 computer costs at least over yuan, and a high-end computer can even cost to yuan.

"If this is the case, the military, major secret research institutes, computer institutes, and even some colleges and universities can purchase a batch!"

Zhao Guoqing said: "Purchasing is okay, but you have to consider keeping it secret. If one of these things is leaked, everyone will know everything!"

Director Liu said: "Of course it needs to be reliable and in demand. The cost of five to six thousand, including research and development expenses, should not exceed ten thousand, right?"

"..."

Zhao Guoqing shook his head.

Director Liu looked at Zhao Guoqing and asked suspiciously: "How much is the research and development cost?"

Zhao Guoqing said: "The acquisition of ARM cost five million U.S. dollars, and the transfer of five backbones of ARM cost 40 U.S. dollars. The Linux system open source laboratory has spent 102 million U.S. dollars, and the software ecosystem has also spent million yuan. , as well as the investment in itself, the investment in tape-out hardware, and the ongoing labor costs, the total investment is no less than million yuan..."

"……so much?"

Zhao Guoqing said: "Anyway, you can only purchase new computers. If you purchase 10,000 units, the cost per unit will be 30,000. If you purchase 30,000 units, the cost per unit will be 10,000... "

Therefore, a large enough market is needed to support the electronics industry. If there is a market for five million units, the R&D cost per unit will only be 60 yuan.

If there is such a large expected sales volume, Teacher Xiao Zhao can completely sell it for only 10,000 yuan as Director Liu said. At this price, there is still a profit of more than 3,000 yuan!

Hey, I can't let go of my hands and feet...

……

Teacher Xiao Zhao left the General Staff and saw Mr. Mu at the door. Teacher Xiao Zhao suspected that Mr. Mu had been waiting for him at the door. In the car, Mr. Mu said happily: "General Master Zhao, the 102nd Institute's new fire control computing chip has been installed, and the test results are good!"

Zhao Guoqing said: "Do you want to have some actual combat drills?"

Mr. Mu smiled and said: "The first batch of six modified J-H-7s have been commissioned into a fleet in the South China Sea, but we haven't had the chance yet..."

"It looks like we will know soon whether it will work or not!"

When I came to the Air Finger Base, I saw that the base was under construction. Teacher Xiao Zhao couldn't directly ask about military matters.

Mr. Mu said: "The base is in the process of installing optical fiber and installing a new air-to-air radar. The new radar will be connected through optical fiber..."

It's a good thing. Radars from different directions are connected together, and the data is processed uniformly. The same target can be scanned. Even the most powerful early warning aircraft has to be effective.

But after reading it, it is no longer the case. The optical fiber is only for communication, not the imaginary data link!

Disappointed!

Mr. Mu said: "What's wrong? Mr. Zhao, is there something wrong?"

"It's okay, it's okay, it's fine!"

Teacher Xiao Zhao thought about making a report to the General Staff. The ADC/DAC chip is already very mature and has been used in two generations of phased array radars. He does not know about other research institutes, but the 101st Institute is fully capable of designing a data connection. system.

Summarizing the signals from various radars into the same computer for processing and comparison can significantly enhance detection capabilities...

Of course, Institute 102 can do it, but Teacher Xiao Zhao is too busy. Zhao Zhongshu called and said: "The rb199 engine is ready. It's National Day. When will you come over to start work?"

Zhao Guoqing said: "Commander Zhao, can you send the engine to Shenzhen City?"

"...National Day, where it is placed, does the security meet the requirements?"

Zhao Guoqing said: "No problem, Director Liu knows the place and the supporting equipment is ready!"

"it is good!"

After Zhao Guoqing saw the radar operation room, he called Director Liu.

"Director Liu, there is something..."

Teacher Xiao Zhao suggested that the 101 Institute send people to complete the construction of the air and ground radar data network!

"The optical fiber has been laid out. It can be completed by adding a digital-to-analog conversion module and a computing center. However, the software still needs some thought..."

Director Liu said: "National Day, can you be so handsome!"

Zhao Guoqing shook his head and said: "Director Liu, Wu Xingbin and You Guoxing from Institute 102 can do it, and Jia Pengfei and Chen Hualing from Institute 101 are very specific about the 1553b bus standard, ADC chip, and radar algorithm, and they can do it. For work, I highly recommend Jia Pengfei, who has conducted in-depth research on polarized signal anti-interference algorithms..."

……

Just when Teacher Xiao Zhao reported his work to the General Staff...

At this time, dense bright spots suddenly appeared on the ground radar screen in the South China Sea.

Operator Zhang Lianyu immediately reported the situation to the command headquarters.

The air command over the South China Sea immediately ordered three J-H-7s to carry out the expulsion mission in accordance with wartime operating procedures.

And these three J-H-7 fighters are the Flying Eagle brigade that President Mu just sent over.

"It's a mule or a horse, it's time to come out and run around!"
