The design of integrated circuits is the key to the era of electronic instruments and intelligence, and there is no need to repeat the great difficulty.

Otherwise, Huawei HiSilicon would not have taken so many years to get out of the Kirin, and the three major factors of capital, manpower, and time are all huge obstacles on the road.

The micro-integration department of Neutron Star Technology Group has just been established, and there is no need to expect to be able to come up with high-performance processors immediately, which is simply unrealistic, and can only reluctantly make small changes to the open source architecture RISC-V.

Zhong Zixing waved his hand to prevent the leaders of the two dozen departments from continuing to take the blame: "There's no need to dwell on such trivial things, if you can't do it well, then try to do it better." ”

In just over half a month, these geniuses made a small change in the architecture instruction set in the way of Chinese programming, and released several instructions, which have exceeded his expectations, although not perfect.

After a moment of silence, Zhong Zixing said: "Since this architecture can't meet our needs, why not start with the basic architecture and overturn the shadow left by the four mainstream architectures on the market: X86, RISC-V, ARM, and MIPS?" ”

All chips on the market cannot escape the influence of these four architectures.

The X86 architecture has high performance, fast speed, and strong compatibility, and has two giants: Intel and AMD. The ARM architecture has low cost, low power consumption, and is suitable for mobile terminals, so Apple, Warwick, Google, IBM, etc. have obtained this authorization.

The MIPS architecture has Loongson, and the RISC-V open source architecture has Samsung, NVIDIA, Western Digital and other companies.

The world's giants in the semiconductor industry have almost not escaped the shadow of these four architectures.

Neutron Star Technology Group used RISC-V when writing the instruction set half a month ago, and it did not escape.

The predecessors have done a good job of architecture, and these architectures have been designed for generations to become more and more powerful, and it is difficult for future generations to come out of these architectures.

But Zhong Zixing is different, among the knowledge he has gained, there are some unbelievable structural methods.

This knowledge was not thorough and confused before, but in the past two years, he has not only learned this knowledge, but his achievements are not low, and he has been able to begin to understand and digest and apply it.

Therefore, it is difficult for others to design their own architecture and completely abandon these four architectures from the bottom, and it is only a matter of time for him.

RISC-V is open source, and everyone can modify, create, and sell on it, but it is impossible for Neutron Star Technology to use this architecture to design a complete chip for sale, so it can only do experiments on it and collect some parameters.

Because once you use it, isn't it helping to augment the database with this architecture?

In the final analysis, this kind of structure belongs to the United States, and if he Zhong Zixing wants to get rid of the dependence on the underlying technology of the United States, he must fundamentally overthrow the architecture and make a fifth architecture that can affect the world.

The idea didn't come all at once, but a long, long time ago.

"Overturning from the ground up and designing an entirely new architecture? This amount of work may require hundreds or thousands of manpower, not to mention, and it also consumes a lot of time and money. Miao Pei, who had a fierce look in his eyes, thought for a moment and said.

She has experience working as an architect at ARM, so she knows how difficult it can be.

ARM processors are inherently 32-bit designed with a 16-bit instruction set, which typically provides up to 35% savings over equivalent 32-bit code, while retaining all the benefits of a 32-bit system.

ARM's processor instructions enable Java acceleration of programming languages to achieve higher performance than software-based Java virtual machines, and reduce power consumption by a full 80% compared to equivalent non-identical programming language acceleration cores.

This architecture is designed to significantly improve performance by increasing the instruction set and providing enhanced 16-bit and 32-bit computing power.

So much so that since last year, the ARM architecture has suddenly exploded in the mobile field, and the market share has now accounted for 50%.

Other architectures have largely been relegated to the mobile space.

Because RISC-V is also adapted to the English programming language, it is not very likely to be adapted to Chinese and achieve perfect processing.

No matter how well their neutron star technology design is, it surpasses the ARM architecture, and they are still working hard for other people's technology.

The mobile phone operating system Android is also open source, but how much has Google won in the mobile era with Android?

"Don't be busy talking about difficulties yet, you have to try it to find out, besides, the more challenging it is, isn't it more exciting?" Zhong Zixing smiled.

Technology is always like this, if you want to open up a new road on the road that the predecessors have taken, you have to pay a greater price, because there are many people walking on the road ahead, and the new road is only them.

"Andromeda, let the calculus task out."

"Okay!"

In the laboratory, Andromeda's light voice came, and a diagram of the infrastructure immediately appeared on the large screen on the wall.

Zhong Zixing stepped forward and took out a laser pointer to explain to more than 30 people in the room: "This is the basic design diagram that I gave Andromeda with a simple idea for it to calculate, and I modified it slightly!" ”

"I'll name it Gemini! Wisdom, enterprising, and studying...... Smart symbiosis with Andromeda! ”

"Of course, this is just a simple basic image, and it doesn't work, and it needs to be modified, experimented, and expanded by you."

The point of the laser pointer points to the oscillator synchronization circuit in the sketch diagram, two amplifiers, voltage reference, and several lines through the comparator, short-circuit protection circuit, converter, etc.

"Because our design must conform to the Chinese design program instruction set and adapt to the artificial intelligence Andromeda, when I design the internal structure diagram, I completely disrupt and reorganize the structure to form a new architecture model."

Although it is only a sketch of the calculation, Zhong Zixing has put in a lot of effort.

Because there is no finished product to feedback the parameters, I don't know what needs to be modified, so I can only follow this line of thought.

One thing is certain, though, that this twin architecture route is the right one.

"Such a chip is designed, the function is strong, the power consumption can also be seen, and the compatibility should be top-notch, but the problem of 32/64-bit dual instruction set is ...... Is the Gemini chip to be carried out at both ends of the mobile phone and computer at the same time? Feng Yingjie's eyes were blazing, and he looked at the screen without blinking.

ARM is a 16/32-bit dual instruction set, but Gemini wants to go up one level, which is almost at the level of a computer, and theoretically doubles the computing speed of ARM.

This challenge is not too difficult, but it is just a matter of doing a wider range of integer operations.

"No, it's the trend to move to 64-bit, the mobile era is coming too fast, and I've heard that Qualcomm is working on 64-bit processors on ARM architecture." Miao Pei explained without looking back.

"Let's go back to your own department first, the HR department has sent out thousands of offers, I don't know how many architects and designers will come, but I think it will soon be out of the dilemma of lack of manpower." Zhong Zixing clapped his hands and brought them back to their senses.

"If the information technology department is concerned, I will take the lead in compiling the instruction set, Professor Li, you will lead the team to complete another task......"
