Wang Anran didn't agree, Wan Yan's video decoding chip physical layout, he has checked it many times, and there will be basically no problems.

And the design is in accordance with the current chip manufacturing standards, so it doesn't matter if you go or not.

As for Wanyan's choice of island country or Wanwan's OEM, this is Wanyan's own choice.

And he now, too, does not have the capital to sit at the same table with these giants.

In the dead of night, it was raining lightly outside the window, Wang Anran put on a military coat, opened the window, and the night was like ink.

A gust of mountain wind blew, and the chill suddenly appeared, General Wang Anran wrapped his coat, took a deep breath, and his thoughts became clear at this time......

Early the next morning, perhaps because of the rain, a sea of clouds suddenly rose on the valley, and a new sun jumped up from the sea of clouds, shining brightly.

"Brother Anran, your luck is good, this spectacle is not something that can be encountered every time. ”

Wang Dongsheng and Gui Zhi also felt that the trip was worthwhile, but the money was a bit too much, which made them feel painful.

The main event has passed, and it should be time to end, Wang Anran looked at his parents, a little reluctant, he had already euphemistically expressed his idea of wanting his parents to go to Yanjing together.

However, the result was expected, as in the previous life, the parents still couldn't leave the countryside.

said goodbye to Lao Jiang and sent his parents back to Jinling, Wang Anran and Hao Fugui embarked on a journey back to Yanjing together......

A month later, the industrial and commercial application was finally approved, and Huaxin Electronics was established in Zhongguancun.

In the process of waiting, Wang Anran was not idle, his own serious IT company, how to play without a computer, can not be employees to work in the computer room of Qingda every day.

But a small motorized unit costs one or two million dollars, on the one hand, the price Wang Anran can't afford it now, and secondly, as an IT master, how can he not have a certain DIY spirit.

Wang Anran set his sights on IBM's Power PC 601 processor, which had been studied in depth during Wang Anran's study abroad, and after entering IBM, he had a deeper understanding of its structural performance.

It is jointly launched by IBM and Motorola, using RISC reduced instruction structure, 800nm manufacturing process, integrating more than 2.8 million transistors, and the main frequency is 50MHz.

Of course, the price of this processor is not cheap, with a single chip price of 1,200 US dollars, which is equivalent to nearly 10,000 yuan.

Wang Anran approached Lu Wei and made an offer to IBM China to order 100 Power PC 601 chips in the name of academic research at Tsinghua University.

Of course, it is not enough for a computer to have a processor, and the scheme adopted by Wang Anran is a compatible machine motherboard design scheme, including memory, hard disk, bus interface, etc., all of which use compatible machine interfaces.

Lu Wei watched Wang Anran designing the PCB circuit board and shook his head.

"Anran, the design point of the small computing center is to be safe and stable, and your 8-way disk array, the speed is improved, but the stability is much worse.

In addition, if one of the eight disks fails, the data of the entire array will be affected. ”

Wang Anran said with a smile: "Teacher, how long do you think this computer will last, a year or two at most, and I have classified it in terms of data security."

Have you noticed that the computer stores general program files and system files is the main one, but the most important data results require relatively few storage resources? ”

The computer structure designed by Wang Anran is targeted to the needs of Huaxin, without big data analysis and multimedia processing, and the security level of data can be reduced.

As long as you back up important data, as for the system crash or program crash due to storage failure, it is also very simple, just reinstall the system.

In fact, the computer is not as fragile as imagined, and it can be seen that the large computer room can be seen that you need to bring a foot cover to enter the computer room, and the floor is also an anti-static floor.

When the maintenance personnel open the computer case, they are like caring for a child, for fear that one accidentally will break the computer.

And in 9102, in the summer, the D big directly opened the case, and even didn't want the case, just find a book to pad under the motherboard.

I look forward to the computer breaking down every day, and I can match the new computer without pressure, but the old computer is not bad, and I am angry.

It took Wang Anran three days to finally complete the design of the PCB motherboard, and the finished design is a 32-way symmetrical SMP multi-processor architecture, sharing 8M*2*32 server ECC memory.

The hard disk storage is a 4G*8 disk array, plus a 4G+4G server dedicated secure storage hard disk, and each computer is equipped with 4 terminals, which can be processed in parallel.

Wang Anran originally thought that the PCB board needed to be OEM, but he learned from Mr. Lu.

Although the country's chip industry has just started, it has also experienced considerable development.

As early as the 80s, the state has invested tens of billions of foreign exchange to establish wafer processing plants and chip packaging projects in Shanghai and Beijing.

Although it lags behind the international mainstream by two or three generations in terms of technology, there is no problem with the production of general auxiliary chips and integrated circuit boards.

Wang Anran read the technical information in detail, and the three-layer PCB board processing technology has no problem dealing with the current low-frequency CPU.

In the name of Tsingda, Lu Wei made an offer to HTC Electronics in Yanjing.

After reading Wang Anran's PCB motherboard design drawings, the other party replied that it can be processed, but some control chips, CPU bases, etc. need to be imported.

"You don't have to think about the CPU base interface, it will be sent with the CPU, and you will install it when the time comes.

The supporting BIOS chip is also purchased by us, but you need to provide a compiler to burn the BIOS system into the ROM chip. ”

"Then it's no problem, we have a ready-made compiler in our factory, and it is estimated that it will take a month to produce, and you can come and pick up the goods directly when the time comes. ”

The three motherboards were sold at the reserve price, and even then, because they were custom-made, the PCB board circuit was redrawn, and the price was as high as more than 30,000 pieces.

In this era, computers are basically insulated from ordinary people, you know, even in Yanjing, an ordinary worker's annual income is only a few thousand yuan.

After finishing the hardware business, followed by the software and operating system, Wang Anran directly chose the IBM power Unix parallel operating system.

This is a system based on RS/6000 parallel multi-processor technology, which was first applied to mainframe computers, and is very suitable for the host computer designed by Wang Anran.

The strength of this system is the efficient algorithm for the task distribution of the processor, coupled with strong support for system security.

If the hardware supports it, this system can remove part of the processor when the system is working normally, or add the processor to the system computing.

The original design was also based on three years of continuous operation without crashing failures.

A system costs $2,000, and if it weren't for the name of Qingda, it wouldn't be able to be bought at all, and IBM wouldn't sell the system alone.

If you have to buy it, you can spend more than a million dollars to buy an IBM host to take home.

As for the Bios program, it needs to be handled by Wang Anran himself, pure machine language, even Hao Fugui can't help.

Wang Anran calculated that the cost of the three computers was 2.6 million yuan, mainly processors, accounting for nearly half of the procurement costs.

Even so, the price of a single unit is controlled at about 860,000, which is only a fraction of the imported IBM minicomputer.

But the performance, after all, each uses 32 of the most advanced Power PC 601 server processors, which is at least three times faster than the IBM 390X minicomputer purchased two years ago in the Qingda computer room.

At this stage, it is more than enough to meet the needs of Huaxin's daily research and development.
