"Yes, brother, these are two very critical questions. Without ultra-large-scale integrated chips, the Kunlun processor architecture and the entire superconducting computer development project will fall into a stagnation stage. At the same time, if the temperature at which superconductivity occurs in Y1 metal cannot be raised, the two development projects will also be interrupted. ”

Nuwa replied in an affirmative tone: "According to my estimates, it will take me at least two years to solve these two problems with the computing power of 4 P595 small computers, and about 1 year for 8 machines. Moreover, there is no guarantee that irresistible factors will occur, and the entire development project will be interrupted. ”

"It's very difficult to integrate chip technology on a large scale and increase temperature technology." After Luo Hai heard Nuwa's words, he couldn't help but shake his head.

He had not yet been in contact with the two planned projects, and when he heard the news and situation given by Nuwa, his heart sank slightly.

After the emergence of integrated circuits in the twentieth century, with the passage of time and the continuous development and progress of science, a new science and technology, microelectronic technology, was formed, which was the cross-integration of solid-state physics, device technology, and electronics.

In the seventies, the whole time entered the era of large-scale integrated circuits, and integrated circuits developed in the direction of integrated systems.

As the core technology of the high-tech and information industries, microelectronics technology, as a basic industry, is developing at a terrifying speed at a terrifying speed, and the reason for this is not only that the technology itself has made a huge contribution to the national economy, but also that it is extremely permeable and related to modern warfare.

With integrated circuits as the key technology, a modern warfare environment characterized by electronic warfare and information warfare, and a broad civilian market demand, the continuous and high-speed development of microelectronic technology has been catalyzed.

In the eighties, VLSI appeared!

Based on the ultra-large-scale integrated circuit technology, scientists have developed ultra-large-scale integrated chips, and after the successful development of ultra-large-scale integrated chips, the development of computers has entered a more rapid stage!

With the mushrooming of supercomputers using large-scale integrated chips, the impact on the national economy, military, people's livelihood and other industries, VLSI technology and chips are strictly guarded by countries with this technology and are strictly prohibited from leaking.

Although the development process of VLSI technology and chips seems simple, it is the crystallization of countless science and technology!

Electron beam, ion beam, X-ray and other photocopying technology, dry etching technology, cutting-edge high-performance lithography machines from sub-micron to nanometers, etc., based on cutting-edge scientific equipment and technology of microelectronics, a marginal discipline, can only be manufactured by a strong country with strong electronic industry capabilities.

However, the core of this qiē is not the cutting-edge high-performance lithography machine worth tens of millions of dollars and the billion-dollar wafer factory, but the silicon in the earth's crust, which is second only to oxygen, and is extremely ordinary semiconductor silicon!

Whether it's microelectronics or countless science and technology, the core around it is the most basic material, silicon!

Now, Luo Hai and Nuwa want to build ultra-large-scale integrated chips based on Y1 metal, a metal element that can produce superconductivity at minus 93.15 degrees Celsius, for the operation of superconducting computers.

The difficulty of this is tantamount to making a heroin addict ban him from smoking again for the rest of his life after half a year of smoking.

Nowadays, Luohai lacks cutting-edge high-performance lithography machines, the technology to make ultra-large-scale integrated chips, and various technologies.

In addition, the ultra-large-scale integrated chip that requires very high accuracy makes Luo Hai's gold ability useless.

With an accuracy of only 0.1 mm, how many circuits can be integrated on a piece of Y1 metal the size of a fingernail?

In order for a superconducting computer to achieve the design performance required by Luo Hai, its manufacturing accuracy needs to be at least 50 nanometers.

Moreover, this is only the problem of ultra-large-scale integrated chips, and the problem of superconductivity produced by Y1 metal is still not solved by Luo Hai.

Difficult!

It's really hard!

Without any equipment, Luo Hai simply could not make a very large-scale integrated chip to raise the temperature at which the superconductivity of Y1 metal occurs.

Gritting his teeth, Luo Hai's brain was running at high speed, thinking about how to solve the biggest obstacle in these two development projects: "At present, the highest accuracy of the gold system is 0.1 mm, and if I want to make a super-large-scale integrated chip, it is not possible, so I must get a series of industrial equipment such as cutting-edge high-performance lithography machines." In order to raise the temperature at which the superconductivity of Y1 metal occurs, I first need a well-equipped material room. It's just that this qiē is very difficult. ”

"Brother, in fact, to increase the temperature of the superconductivity phenomenon of Y1 metal, we can temporarily adopt a compromise method, in the process of use, a large number of liquid nitrogen equipment is stored, and the internal structure of the superconducting computer is designed to cool down the liquid nitrogen. However, this requires a lot of liquid nitrogen to be stored. At this time, Nuwa continued: "As long as the space with us continues to expand, the limitations of superconducting computers will be greatly reduced. ”

Luo Hai nodded, and then said: "Well, Nuwa, you continue to design the drawings now, and I will solve the problem of ultra-large-scale integrated chips." By the way, Nuwa, are you sure that you can make smart machines? ”

"What kind of intelligent program is the intelligent machine, brother? What is the focus? Hearing Luo Hai's words, Nuwa was silent for a while, and then replied.

Luo Hai thought for a moment: "Able to have conversations with people, and highly agile physically, humanoid, specializing in industrial manufacturing and logistics maintenance. ”

If you want to manufacture ultra-large-scale integrated chips, it is not enough for Luo Hai alone, not to mention manufacturing, even a series of chip manufacturing equipment such as cutting-edge high-performance lithography machines are a problem.

Between the artificial intelligence of Nuwa, Luo Hai came up with the idea of creating a smart machine.

"Well, yes, but brother, we need the Loongson 4A central processing unit of the Chinese Academy of Sciences and the Red Dragon H1 single-chip microcomputer, as well as a large number of basic raw materials and supporting equipment." Nuwa replied in the affirmative:

"Of course, for now, we only need to get the Loongson 4A central processing unit and the Red Dragon H1 single-chip microcomputer, brother, you use the basic raw materials of the ability control to create the shape of the machine, install it, and I will design the intelligent control system." However, this cannot be applied to large-scale industrial production. ”

Hearing Nuwa's words, Luo Hai replied helplessly: "Loongson 4A and Red Dragon H1 type, this is really high enough. ”

Loongson 4A aerospace-grade central processing unit adopts real yàn room 22nm manufacturing technology, the highest main frequency can reach 3.5GHz, supports vector operation acceleration, and the highest peak computing capacity is up to 392GFLOPS!

The performance-to-power ratio is extremely high, and the performance of the computer using Loongson 4A aerospace-grade central processing unit is several times higher than that of ordinary computers, and the 'Tianhe-1' supercomputer that shocked Americans is the Loongson 4A aerospace-grade central processing unit.

Loongson 4A aerospace-grade central processing unit, the performance is really very attractive, Luo Hai saw it in the base library, and he was eager to get one or two.

It's just that the Loongson 4A aerospace-grade central processing unit is not something you can get if you want to, and Luo Hai had no way to place an order in the national star electronics room of the Chinese Academy of Sciences.

The Red Dragon H1 space-grade single-chip microcomputer is also the same as the Loongson 4A space-grade central processing unit, and even its confidentiality level is even higher, so that there is no information about the Red Dragon H1 space-grade single-chip microcomputer on the entire network.

Nuwa, this girl, has a mouth, and she wants Loongson 4A CPU and Honglong H1 microcontroller, and Luo Hai can't find it at all.

"Nuwa, you started to design the number jù and drawings of the smart machine, and we temporarily made it in the early stage. I have to get acquainted with the teacher to see if I can get Loongson 4A and Red Dragon H1, by the way, how many do you want each? ”

Luo Hai shook his head, fortunately, his master was the former deputy minister of the Ministry of Technology and Science of the Chinese Academy of Sciences, to see if he could get the Loongson 4A and the Red Dragon H1 through Master Guò.
