As many domestic companies as possible have launched independent and controllable domestic chips to gradually replace foreign chips. I believe this is the common expectation of most netizens.
So what kind of domestic chips are truly autonomous and controllable? Maybe many netizens have no idea. Even if the chips of domestic brands are autonomous and controllable, they are not actually. Let’s talk about this issue today.
Regarding self-controllability, academician Ni Guangnan once proposed three major standards. The first is whether the CPU development unit meets the requirements of security and confidentiality. The second refers to whether the CPU instruction system can sustainably develop independently. The third is whether the CPU core source code is written by yourself.
As for the first standard, I believe that many companies can reach it. If we don’t start to do too much discussion here, we will naturally understand what we know.
As for the second standard, what everyone should pay attention to here is that the instruction set is not necessarily purely domestic, as long as it can be autonomous and sustainable. Even if everyone uses the ARM architecture, as long as they have permanent authorization and can continue to develop chips based on the ARM authorized architecture, they will not kneel down because of ARM’s interruption of supply.
For example, the Kirin chip, although it uses the ARM architecture, but Huawei has a permanent authorization of ARMV8, and the subsequent development of chips based on the ARMV8 architecture at any time is not restricted by the ARM architecture, and it is also eligible.
The third standard refers to whether the core source code was written by yourself. This involves patents and core code issues. The deeper meaning is that you are not under the control of others. You can innovate, modify, and adjust yourself. Disputes over patents and versions.
These three points are necessary, but judging from the current situation, in addition to these three points, we have to consider the manufacturing aspect. Because the current external situation is more complicated, such as Huawei’s Kirin chip that meets the previous three requirements, but in the end it is still limited in the production stage, which is uncontrollable.
It can be seen that it is not easy to truly become an independent and controllable domestic chip. It requires the cooperation of the domestic industry chain to achieve independent control from design to manufacturing. It is not enough to rely on the strength of one or a few manufacturers.
