Gao Zhen was stunned. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

As an electronics undergraduate graduate with excellent grades, he is naturally no stranger to the Internet. And during the university study, under the guidance of teachers, they also made their own network cards, network cables, wrote software, and built a local area network by themselves, so as to have a deeper understanding of it.

The difficulty of network transmission is not in the software such as coding standards, but in the lack of hardware.

Taking the ADSL network technology that appeared in normal history as an example, although it began to be studied as early as the eighties, it was not until the early nineties that it gradually began to be applied. And the initial home ADSL network, the transmission rate is only, and then with the development of integrated circuit technology, the network has been accelerated many times, and then gradually increased to 1M, 1. 5m, 2m, and then obsolete by faster fiber optic networks.

In earlier versions, the decoder chip solidified in an ADSL modem was manufactured to the million-dollar device level.

This is the reason why the maximum decoding rate of modems in this era can only reach tens of kb, and most modems used in home, commercial, and even ordinary scientific research institutes are only a dozen kb.

Think about it, even the 286 processor, which represents the highest level of the microelectronics industry, can only reach the level of integrating 130,000 yuan devices, how can it be possible to make a high-speed modem with an integration degree of up to one million?

It's not about design, it's about hard power!

Like Gao Zhen and their school, students design their own circuit diagrams, write their own software, make their own masks, tape-outs, and use three-micron process technology to make their own modem and demodulation chips, whose transmission rate can only reach 28 kilobytes, which is already the world's leading technology, if sold as a commercial chip, it can also find a place in Silicon Valley, where elites gather.

However, the fat uncle from the personnel department in front of him actually told him that the base was building an information trunk with a transmission rate of up to 200 G, which completely frightened him.

Two hundred g's trunk, what is this concept......

If calculated at an instant transmission rate of 2 megabits per user, this fiber optic trunk can carry 100,000 users at the same time and connect with the maximum amount of data. If each user has one megabyte of bandwidth, it can accommodate 200,000 users online at the same time. If it is reduced to 400,000, the number of simultaneous users can be as high as 400,000!

At present, there are not even 400,000 people in the new city!

Quantifying it as the component integration of the decoding chip, a 512k bandwidth channel needs 300,000 chips, one trillion bandwidth needs to reach 500,000, and two trillion bandwidth rises to 1.3 or 400 million.

At this point, his heart moved, and he immediately asked, "How much bandwidth is allocated for each computer?" ”

"I heard from the technicians of the construction team that we are a scientific research unit here, which is quite special, so each user can guarantee two megabytes of bandwidth. At present, we are temporarily allocated 200 computers, so the program control center only has 500 channels installed. However, after the initial equipment is installed, the number of channels can be increased by adding a substrate in the future, and the expansion is very convenient. Deng Rui was very talkative, and told him all the information he heard in detail.

Two trillion!

Gao Zhen felt a little dizzy.

Two megabytes is a million-level chipset, and if it is split into multiple chips, it involves information exchange, and the speed will be greatly reduced. Therefore, the chip used in the decoder board is properly at the million-level level!

He felt that the world in front of him was a little unreal.

When has the manufacturing process of million-integrated chips been mastered? Since there is already such a good manufacturing technology, why is the school still teaching three-micron process technology, even the actuarial type one integration degree is only 60,000, I heard that the latest actuarial type one change for game consoles has increased the integration degree to 150,000.

Judging from the scientific and technological journals purchased in Hong Kong, this is already the world's highest integrated technology.

Could it be that the base area obviously has integrated circuit manufacturing technology far beyond the current process level, but deliberately only comes up with chips of a lower level for export sales?

The doubts in Gao Zhen's heart are precisely the facts.

In the Guan Fei Private Research Institute, researchers have long completed the manufacturing of chips with a higher level of integration under his guidance, and summarized the detailed process flow, but it has not yet been promoted. Of course, it has not yet reached the million level, but it has only tripled the level of public technology and reached 500,000 integration.

It's not that the million-level can't be done, but the cost performance is too low.

After all, the more in-depth the micro processing technology, the higher the requirements for the equipment, before the manufacturing level has not been greatly improved, the manufacturing difficulty has increased exponentially, and the cost is so high that even Guan Fei can not afford it.

Not to mention the million-level, even the 500,000-level, if all the integrated circuit production lines in the base area are not replaced, they can only be produced in small quantities by the laboratory, and there is no value for large-scale promotion.

And the first production line has only been put into operation for less than a year, and it has been replaced with a new ......, and the loser is not so defeated!

In Guan Fei's plan, advanced technology, which was ten years ahead of the times, remained only in his personal laboratory. After two years, it will be transferred to a general scientific research institute; Five years later, it continued to expand outward to precision manufacturing; Ten years later, it will be fully popularized to all electronic enterprises.

In this way, it not only ensures the leading technology, but also not only attracts external commotion, thus endangering the security of the base area itself.

He speculated that other countries were doing the same.

Who doesn't have a few killer moves.

Just as there is a tradition of production, research, and pre-research in China, there must be a similar replacement process in the American science and technology community. He doesn't believe that the current top level of integrated circuit manufacturing in the United States is really only 130,000 at the 286 level, and maybe in some unknown secret R&D base laboratory, research on integrated circuit manufacturing at the level of 500,000 is underway, even if it is at the million level, it is not impossible.

He's kind of following tradition......

As for the two-megabit channel chip, it is really the same as Gao Zhen guessed, and it was only achieved by him splitting the circuit into multiple chips. This is only the frequent exchange of information, often involving a variety of data processing needs of scientific research institutes, in order to enjoy this kind of cost of over-specification treatment, ordinary university laboratories can only be allocated to each computer to one trillion bandwidth, factories and enterprises can only be allocated to 512 bandwidth, ordinary home users can only be allocated to 128 bandwidth.

In terms of the chips needed for each channel, scientific research institutes need to use three 500,000-level decoding chips for each channel, universities need two for each channel, and factories and enterprises need exactly one chip for one decoding channel.

As for ordinary individual users, it is also a chip corresponding to a decoding channel, but the modem they use does not use a high-performance chip of the 500,000 level, and its internal solidification will be an actuarial type 1 decoding chip.

It's also about avoiding leaks.

Computers in scientific research institutes, universities, and factories are all in a state of protection, and the exchange equipment is the focus of care, and outsiders cannot see how many chips are used in it without disassembling the equipment shell, and it is even more difficult to steal them for reverse research.

However, ordinary users cannot supervise it, and they do not need too high information transmission speed, and the decoding rate is enough to be completed with an actuarial type 1 decoding chip.

Even if it is reduced by so much, the ordinary users in the base area are still happy compared to foreign users, because the high-speed information network they use will be the fastest and most popular in the world!

Gao Zhen was preoccupied, followed Deng Rui to the end of the main road at the door, and when he was about to arrive at the main office building of the institute, Deng Rui pointed to a milky white steel-shell building similar to a transformer bank in the community and said: "Look! This is the switching equipment of our institute, and it is it that supports all the data exchange work. ”

Gao Zhen looked up and was taken aback by its size.

The exchange unit is a boxy cube, three meters long on each side, two stories high, and completely sealed on the outside. Only in the direction of the entrance of the research institute, there is a small door, which is probably used for internal maintenance and equipment replacement, but at this time, the small door is tightened and cannot be pushed open to see the internal situation.

The small gate is facing the main road, and it is within the guard's field of vision, so it will be difficult to break it and sneak in.

The buzzing sound of equipment running in the building sounded somewhat like the sound of air conditioning.

He saw this small building-like building outside, but at the time he thought it was where the security personnel lived, and now he realized that it was the fiber optic channel switching equipment unit.

"It's huge!" Gao Zhen sincerely exclaimed, and then nodded.

Although he is in professional habits, he still has doubts about the process of the decoding chip used in the base, but seeing such a large equipment operation room has solved half of his doubts.

Even if 150,000 integrated chips are used, such a large building can accommodate it......

Probably.

Gao Zhen didn't dare to wander around when he first arrived, so he followed Deng Rui into the office building, stayed honestly in the personnel office on the third floor, and found newspapers and magazines from the newspaper shelves to pass the time.

In addition to the newspapers and periodicals of a strong political nature, such as the newspaper of the Organs of the Establishment of the Establishment of the Establishment of the Newspaper, the Liberation Daily, and the Newspaper of the Workers, which are run by the base areas, there are also Xincheng Daily, which is closer to the lives of the common people and has a strong sense of entertainment. In addition, it is a scientific research unit after all, although it is a personnel department, there are also science and technology newspapers and magazines such as Science and Technology Times and Science and Technology Weekly.

Most of these science and technology magazines are regularly sent back from Suteng Commerce and Trade branches in various countries, including science and technology newspapers in Europe, America, East Asia, and even Eastern Europe, and the most authoritative and representative news of scientific and technological research and development progress are selected by the editorial department, and translated into Chinese and published as popular scientific and technological publications.

The most are professional journals, whether it is "Science", "Nature", "Royal Society of London" and other comprehensive scientific and technological journals, or more in-depth "Journal of the American Statistical Association", "London Mathematical Bulletin", "Journal of Fluid Mechanics", "Physical Review Letters" and other professional journals, there are everything, the number of no less than two hundred!

Most publications were published a month or two later than normal, and the translation had to be delayed in order to translate them into Chinese. There are also some tomes that do not have time to translate, so they have to buy the original version directly and display it for those researchers who are fluent in foreign languages to read.

Of course, all of these publications are pirated, and they are officially pirated!

Although in order to help scientific researchers keep abreast of global scientific and technological trends and keep track of the latest scientific and technological research, the base area has hired hundreds of translators who are proficient in foreign languages from China to translate various foreign language journals month by month, and then print and publish them on a large scale. In addition to requiring compulsory subscriptions from various scientific research institutes, universities, and industrial and mining enterprises, the publications are also sold to the outside world at a low price, so that although the base area is cramped in the mountains, it is well aware of the global scientific and technological trends.

However, the original publisher and author did not receive a penny of remuneration.

Recently, China's Xinhua bookstore has also sent a working group to the base to join the large-scale government-backed intellectual property piracy campaign.
