The Intel Vulnerability Gate incident shocked the world!

By the time Ferro returned to the office, news from around the world had filled his desk.

One of the attitudes that the world has shown is that it is extremely distrustful of Intel.

The key is that Intel still has a hard time arguing.

In the end, the official emergency public relations of the United States gradually calmed down the matter.

However, the impact of this incident is far from stopping, and officials of various countries are considering whether to pin their national security on the chips of other countries.

As the initiator, Huaxin Technology, in line with the attitude of not being afraid of big things, insisted on suing Intel in the Chinese court, which was naturally sought after by the people who eat melons, and finally gathered into more than 500 enterprises and institutions and hundreds of thousands of people in class lawsuits.

Finally, Intel had to issue an announcement announcing that Chinese mainland would be included in the recall program.

On this day, countless people who eat melons celebrated, and Huaxin Technology also issued a statement, saying that Intel had made the wisest decision.

Historically, because of the division operation bug, Intel actually paid more than 300 million US dollars for recall, and this time plus compensation, Intel paid a total of 1.7 billion US dollars, and for a while, it was greatly damaged and had to interrupt the development of some key technologies.

On the thirteenth floor of Yanjing Pioneer Building, as a test of the CPU division, a team of more than 30 people finally handed in the first job.

This is a set of instructions.

Like a software program, hardware can be conceived as a hardware program.

Hardware programs are also meant to deal with related objects.

As a CPU, the problems that need to be dealt with are much more complex than those of the GPU, which mainly performs image processing.

First of all, the most basic, CPU needs to face scientific operations, which involves a series of mathematical theories such as series and Fourier transforms.

The program will only tell the CPU, you have to make an open square for me.

If you happen to hit 1, 4, 16, and the square just happens to hit an integer, it's very simple, but if you happen to hit a number like 5, 6, 7, you get the CPU to open the square, it's a bit hard.

So the first thing you have to do is to teach the CPU how to do the calculations, which is to turn the open square through the series transformation into addition, subtraction, multiplication and division that the CPU can understand, as well as some matrix calculations.

This method is known as the scientific computing instruction set.

Of course, the scientific computing instruction set is not only a processing method, but also involves the call of some registers and accuracy calculation.

Secondly, the CPU also needs to control the I/O equipment, read and write the memory, read and write the hard disk, process audio and video multimedia applications, process and call the image, and even the workflow and unit call within the CPU.

This complete set of CPU instructions is called the instruction set.

Object-oriented, logical can be visualized, but don't forget that these instruction sets are integrated into the CPU in the form of circuits.

For Wang Anran, the instruction set is like his own son, who can write hundreds of instructions from AMD Ryzen processors one by one and explain in detail how the instructions are implemented.

The biggest reason for the establishment of this CPU division is also to hide people's eyes.

Wang Anran will go to the CPU business department as long as he has time, and watch these stunned young people start from the most basic information and study classic cases, to try to design some instructions, to abandon and redesign.

Along the way, Wang Anran was also guiding step by step, and when he encountered a bad brain, Wang Anran even wanted to kick it, "Silly boy, do you really want me to tell you word by word, don't you have a little understanding?"

It took a year and a half to finally hand in an answer that Wang Anran reluctantly accepted.

This covers some of AMD's 3D now instruction strategies, intel SSE partial instruction strategies, and ARM and MIPS instruction strategies developed three years later.

With Wang Anran's vision in 9102, the director of Bo Zhong can perfectly avoid Intel's patent barriers under the X86 instruction architecture.

In fact, the x86 architecture is a complex instruction architecture, and Intel is also moving closer to RISC when designing the Pentium triple processor, adding many reduced instructions.

The advantages and disadvantages of the two instruction set architectures are obvious, and Wang Anran has always believed that one should not stick to one type, and learning from each other's strengths is the king.

In fact, whether it is Core or Ryzen, there have been very successful attempts in this regard.

With the instruction set and EDA software, Huaxin Technology has finally taken a gratifying step in CPU design.

Huaxin Technology registered the instruction set as a patent at the first time, and Huaxin Technology used the SIMD series single-instruction multi-data stream CPU version in the GPU (used for a single instruction to control multiple processing units, which can significantly improve CPU work efficiency)

The entire instruction set system can be declared to be complete, with a bias towards complex instruction architectures, suitable for desktop processors.

Of course, no one can guarantee 100% problem-free, and computer simulations can find most of the bugs.

At the same time, the instruction set design team was assigned another task, that is, to design a set of instructions that favored the RISC reduced instruction architecture, which can now be partially explored, which Wang Anran is preparing to compete with ARM on mobile platforms in the future.

............

After a busy day, Wang Anran shook his head.

"It seems that I will have to come here more often to guide the work in the future. ”

At this time,It's not realistic to get X86 authorization at all,Since you have an open-source Hongmeng sp system,There is a graphics card,Game drainage,You can try to develop your own ecological closed loop。

When Huaxin Technology masters the same processor technology as Intel, at that time, I am afraid that the Americans will beg for authorization of Huaxin Technology's X86 technology.

This routine is very skillful in the United States.

Historically, when China has made a major breakthrough in a certain technology, Western countries will always export similar technologies to China at a very low price at the first time.

R&D expenses are huge, and they are also exposed to risks, while the introduction of mature technology, except for money, does not have any risks.

The purpose of imperialism is to cut off the R&D spirit of the Chinese people, so that you can become attached step by step, step by step.

What Wang Anran needs is not X86 technology, but the authorization of X86 instruction architecture.

He can't judge how far Huaxin Technology's instruction set architecture can go.

In fact, in the past 30 years, Wang Anran has seen too many excellent designs, from stunning to obscure.

The reason is very simple, it is interests and games.

No matter how good your design is, no matter how good your performance is, you still don't have a move, after all, Huaxin Technology, and even the whole country, basically have no say in the semiconductor field.

The formulation of an industry standard can nail you to death.

Huaxin Technology's graphics card is off the beaten path, but you also have to obey other people's interface standards to play, you have to design your own I/O interface to see, there will be no manufacturer in the world to ignore you.

If the authorization of the X86 architecture is obtained, it will be different, Huaxin Technology can attack, retreat and defend, and can compete with Intel in the home of X86......

On this day, Wang Anran is looking forward to it.
