Since the United States implemented the chip ban, domestic chip companies such as Huawei and SMIC have suffered hardships in the supply chain. It is not only the monopoly of core manufacturing equipment materials such as EUV lithography machines, but also the two most mainstream architectures, X86 and ARM, have gradually been closed by the United States to high-tech Chinese companies.

You should know that the architecture is the upstream industry of chip . Without the corresponding technical authorization, there is no way to talk about subsequent design and manufacturing. Obviously, the US move is to completely press the pause button for the development of domestic chips.

But Chinese people have never been afraid of difficulties, nor are they lacking the spirit of overcoming difficulties. The United States probably did not expect that the dimensionality reduction attacks it used to use the advantages of basic architecture technology not only did not stagnate the development of domestic chips, but instead prompted domestic institutional companies such as Huawei, Alibaba , and Chinese Academy of Sciences to accelerate their investment layout in the field of RISC-V architecture.

As of the 14 senior members of RISC-V, 11 of the companies are from China. In other words, in the field of chips based on the RISC-V architecture system, we have absolute voice.

However, compared with the two mainstream architectures of X86 and ARM, RISC-V is a rising star, the ecosystem is not mature enough, and the market share is also quite different.

But what people unexpectedly expected was that a dramatic reversal occurred. Recently, the US technology giant Google announced its decision to officially include the RISC-V patch of Alibaba flat-headed semiconductor in Google's source code. This means that Google Android will support RISC-V architecture in the future, which is equivalent to joining the "Chinese camp".

Everyone knows that Google's Android system and ARM architecture chips have always been highly bound, and in recent years, the United States has been constantly promoting the plan to "decouple" from our technology. So the question is, why did Google suddenly turn its attention to the RISC-V architecture?

The answer is very clear. Although the size of the RISC-V architecture is still far less than that of X86 and ARM for the time being, it has many advantages such as open source, free, simplicity, and strong compatibility. What’s more important is that with the efforts of Chinese companies, the RISC-V architecture has grown rapidly in recent years. Up to now, the RISC processor "Xiangshan" created by the Chinese Academy of Sciences has successively launched two cores, "Yanqi Lake" and "Nanhu". Some of Huawei's smart home appliances also have RISC-V architecture on its core processors.

In addition, Alibaba released the RISC-V chip Yitian 710, its performance has reached the world's top level, and the world's first high-performance chip development platform "Wujian 600", was independently developed by Alibaba's Pingtou Ge Semiconductor based on the RISC-V architecture system.

Thanks to this, many industry insiders believe that RISC-V can grow into the third global mainstream architecture beyond X86 and ARM in the future. Naturally, Google does not want to fall behind in future competition, which may be the main reason why Android systems rely on the RISC-V architecture.

is actually not just Google, but even the US chip giant Intel , which holds X86 architecture , is optimistic about the potential of RISC-V. After it failed to successfully try to acquire this architecture, it invested billions of dollars to establish a special technology development center for RISC-V architecture. But these American companies are obviously one step too late to speak about the future of RISC-V architecture.

Now it seems that the call of the old academician Ni Guangnan has worked. Since the domestic market was cut off from its core, Academician Ni Guangnan has publicly expressed on many occasions that he hopes that our companies can appropriately focus on the RISC-V architecture system and create new opportunities for the development of domestic chips.

As an older generation of chip experts, Academician Ni Guangnan knows the importance of mastering core technologies. More than 20 years ago, because Liu Chuanzhi and others insisted on " comprador ", Ni Guangnan, who advocated self-development, was forced to leave Lenovo , and we also missed the golden twenty years of rapid development of the semiconductor industry.

Fortunately, after experiencing the "bottleneck" pain, the domestic market has thus strengthened its independent route, and many Chinese companies have also recognized the situation and began to increase R&D investment. Now, under the guidance of senior Academician Ni Guangnan, we have not only not repeat the same mistakes in the field of RISC-V chip architecture, but also achieved a leading position!

is completely predictable. With the continuous efforts of Chinese companies in the field of RISC-V architecture, domestic chips will actually achieve a faster rise, and breaking the Western technology blockade is just around the corner!
