Chapter 253 Hierarchical Technology Diffusion
Gao Zhen was stunned when he heard this.
As an electronics undergraduate graduate with excellent grades, he is naturally familiar with the Internet. And during his college study, they also made their own network cards, network cables, wrote software under the guidance of teachers, and built a local area network, which made a deeper understanding of it.
The difficulty of network transmission is not the software such as coding standards, but the hardware shortcomings.
Taking the adsl network technology that appeared in normal history as an example, although it was studied as early as the 1980s, it was not gradually applied until the early 1990s. And the initial home adsl network was only 512kb. Then, with the development of integrated circuit technology, the network has undergone multiple speedups and gradually increased to 1m, 1.5m, and 2m, and was subsequently eliminated by faster fiber optic networks.
In earlier versions, the manufacturing process standard of a decoding chip cured in an adsl modem is the device level of one million yuan.
This is still achieved by only one channel, splitting the receiver and decoder into two parts and splitting them on two integrated circuits!
This is why the maximum decoding rate of modems in this era can only reach a few dozen kb, and most modems used in household, commercial, and even ordinary research institutes are only more than ten kb.
Think about it, even the 26 processors representing the highest level of the microelectronics industry can only reach the level of integrating 130,000 devices. How can it be possible to produce a high-speed modem with an integration level of up to one million?
It's not about design, it's about hard power!
In school, like Gao Zhen and others, students design circuit diagrams themselves, write software themselves, make masks and flow strips themselves, and use three-micron process technology to make modem chips, whose transmission rate can reach only 28,000 bytes, which is already the world's leading technology. If sold as commercial chips, they can definitely gain a place in Silicon Valley where elites gather.
But the fat uncle from the Personnel Department in front of him actually told him that the base was building an information trunk line with a transmission rate of up to 200 g, which completely scared him.
Two hundred g trunk lines, what is this concept...
If calculated based on the instant transmission rate of 2 megabytes per user, this fiber trunk can carry 100,000 users at the same time and connect with the maximum data volume; if each user has one megabyte bandwidth, it can accommodate 200,000 users online at the same time; if it is reduced to 512kb, the number of users used simultaneously can reach 400,000!
There are currently no more than 400,000 people in the new city!
Then quantify it into the component integration degree of the decoding chip. A 512k bandwidth channel requires 300,000 chips, one mega bandwidth needs to reach 500,000, and two mega bandwidth increases to 130,000 and 400,000.
After counting this, he felt aroused his heart and immediately asked: "How much bandwidth is the allocated by each computer?"
"I heard from the technicians of the construction team that we are a scientific research unit, which is quite special, so each user can guarantee two megabits of bandwidth. Currently, we are temporarily allocated 200 computers, so the program control center only has 500 channels installed. However, after the equipment is installed in the early stage, you only need to add a substrate to continuously increase the number of channels, and it is very convenient to expand the capacity." Deng Rui spoke very easily and told him in detail all the information he heard.
Two trillion!
Gao Zhen felt a little dizzy.
Two Gigabits are a million-level chipset. If it is split into multiple chips, the speed will be greatly reduced when it comes to information exchange. Therefore, the chip used on the decoding board is definitely a million-level chip!
He felt that the world in front of him was a little unreal.
When did the base area master the manufacturing process of a million-level integrated chip? Since there is such a good manufacturing technology, why is the school still teaching a three-micron process technology, and even the integration of actuarial one type is only 60,000. I heard that the latest actuarial one type modification used for gaming consoles has increased the integration to 150,000.
Judging from the technology journals purchased in Hong Kong, this is already the world's highest integrated technology.
Could it be that the base has an integrated circuit manufacturing technology that is far beyond the current process level, but it deliberately only uses lower-level chips to be used for export?
Gao Zhen’s doubts in his heart are exactly the facts.
At Guanfei Private Research Institute, under his guidance, researchers have completed chip manufacturing with higher integration and summarized detailed process flows, but they have not yet been promoted. Of course, it has not reached the million level, and it has only doubled the level of public technology, reaching 500,000 integration.
It’s not that the million-level level is impossible, but that the cost-effectiveness is too low.
After all, the deeper the microprocessing technology, the higher the requirements for equipment. Before the manufacturing level has been greatly improved, the manufacturing difficulty has increased exponentially, and the cost is so high that even Guan Fei cannot bear it.
Not to mention the million-level or even the five hundred thousand-level, if all integrated circuit production lines in the base are not replaced, they can only be produced in a small amount by the laboratory, and they do not have the value of large-scale promotion.
The first production line has just been put into production less than a year ago and it has been replaced with a new one... It’s not like this that the loser is not defeated!
In Guan Fei's plan, advanced technology that surpassed the times for ten years was only retained in his personal laboratory. After two years, it would be transferred to ordinary scientific research institutes; in five years, it would continue to expand to precision manufacturing; in ten years, it would be fully popularized to all electronic companies.
This not only ensures the leading technology, but also causes external disturbances, thus endangering the own safety of the base area.
He speculated that other countries did the same.
Who doesn't have many killer weapons?
Just like there is a tradition of producing one generation, researching one generation, and pre-research one generation in China, the American technology community must have similar replacement processes. He does not believe that the top level of integrated circuit manufacturing in the United States is really only at level 26 of 130,000. Perhaps in the laboratory of an unknown secret research and development base, research on the manufacturing of integrated circuits at level 500,000 is being carried out. Even if it is a level 100,000, it is not impossible.
He can be considered as following the tradition...
As for the two-megapixel channel chip, it is really just like Gao Zhen guessed that it was achieved by splitting the circuit into multiple chips. This is only possible for research institutes that frequently exchange information and often involve various data computing needs to enjoy this cost-effective treatment. Each computer in an ordinary university laboratory can only be allocated one megapixel bandwidth, factory enterprises can only be allocated 512 bandwidth, and ordinary home users can only be allocated 12 bandwidth.
In terms of the chips required for each channel, each channel of the research institute must use three 500,000-level decoding chips, two for each channel of the university, and one chip corresponds to a decoding channel for the factory and enterprise.
As for ordinary individual users, a chip corresponds to a decoding channel, but the modem they use cannot use a high-performance chip of 500,000. The internal cured will be an actuarial one-level decoding chip.
This is also to avoid leaks.
Computers in research institutes, universities, and factories are all in a state of protection, and switching equipment is the focus of supervision. If outsiders do not disassemble the equipment shell, they cannot see how many chips are used inside. 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. The decoding rate of 12kb is enough to be completed with an actuarial and level-changing decoding chip.
Even if it has been reduced so much, ordinary users in the base area are a kind of happiness compared to foreign users, because they will use the fastest and most popular high-speed information network in the world!
Gao Zhen was worried and followed Deng Rui to the end of the main road at the door. When he was about to arrive at the main office building of the institute, Deng Rui pointed to a transformer group similar to the community, and said: "Look! This is the exchange equipment of our institute, which supports all data exchange work."
Gao Zhen looked up and was startled by its size.
This exchange equipment group is a square cube, each side is three meters long and two floors high, and the outside is all sealed by welding. Only a small door is opened directly opposite the gate of the institute, which is probably used for internal inspection and replacement of equipment. However, the small door is tightened at this time and cannot be pushed open to see the internal situation.
The small gate is opposite the main road, and is within the guard's observation field. If you want to destroy and sneak in, it may be difficult to do so.
The sound of buzzing equipment running came from the building, which sounded a bit like the sound of air conditioning.
He saw this small building like a building outside, but he thought it was the one where the guards lived, but now he realized that it was the fiber optic channel switching equipment unit.
"So big!" Gao Zhen exclaimed sincerely, then nodded.
Although he was in a professional habit, he was still worried about what process the decoding chip used in the base was, but seeing such a large equipment operation room, he solved half of his doubts.
Even if it uses 150,000 integrated chips, such a large building can accommodate it...
perhaps.
Gao Zhen was just a little while ago and did not dare to wander around. He followed Deng Rui into the office building and stayed honestly in the personnel office on the third floor. He found newspapers and magazines from the newspaper shelves to pass the time.
In addition to the strongly political newspapers and newspapers such as the Bible, Jiefang, and Bible Workers' newspapers run by the bases, there are also Xincheng Daily, which is closer to the lives of the people and has a strong entertainment. In addition, it is a scientific research unit after all. Although it is a personnel office, it also includes science and technology newspapers and magazines such as Science and Technology Times and Science Weekly.
Most of these science and technology magazines are sent back from Sagitar Trading branches in various countries, including science and technology newspapers and magazines from Europe, America, East Asia, and even Eastern Europe. The editorial department selects the most authoritative and representative scientific and technological research and development progress news and translates them into mass science and technology publications published in Chinese.
The most common are professional journals, whether it is comprehensive scientific and technological publications such as Science, Nature, and the Royal Society of London, or the more in-depth selected journals such as the Journal of the American Statistical Society, the London Mathematics Bulletin, the Journal of Fluid Mechanics, and the Physics Review Letter. There are all available here, with no less than one or two hundred types!
Most publications are published one or two months later than normal. In order to translate them into Chinese, they have to postpone the translation version. Some large numbers have no time to translate them, so they have to purchase 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 official pirated versions!
Although in order to help scientific researchers understand global scientific and technological trends in a timely manner and track the latest scientific and technological research, the base has hired hundreds of foreign-school translators from China to translate various foreign journals month by month, and then printed and published on a large scale. In addition to requiring various scientific research institutes, universities, and industrial and mining companies to subscribe, the publishing publications also sell them at low prices, making the base areas very familiar with global scientific and technological trends in the mountains.
However, the original publishing house and the author did not receive a penny of royalties.
