Huawei has a permanent license to develop ARMv8 independently for a long time

So the question is, if foreign countries really blockade technology, domestic companies can not survive? One of the hot topics on the Internet is Huawei's Kirin processor, which uses the instruction set of ARM. If it is disabled, what will Huawei's ARM processor do? This is unlikely to happen, but Huawei has been granted a permanent license to design an ARM processor on its own.

ARM was originally a British company. It was acquired by Softbank in 2016. Now it is a Japanese company. Its ARM instruction set is widely used in embedded and mobile industries. Its business revenue mainly comes from authorization and royalty revenue of ARM instruction set. The companies that really develop ARM processor chips are Apple, Samsung, Qualcomm, Unicom and Huawei. And each company accepts different authorization modes.

For ARM processors, netizens are enthusiastic about two issues. One is that companies with self-research architectures are better, such as Qualcomm and Apple. Other companies adopt the public version of ARM, which can be purchased and used without technical content. The second problem is that if ARM does not provide authorization, these companies will die. Those who think that it's easy to be a processor with ARM authorization are not worth refuting. They just don't know anything about chip design. But the second problem is not so easy to understand. This involves the IP authorization mode of ARM.

Other companies don't say that without the ARM license, would Huawei's ARM processor business be doomed?

Over the weekend, I saw a picture on the Internet explaining the IP authorization mode accepted by Huawei's ARM processor. Huawei has obtained the permanent authorization of the ARMv8 architecture. ARMv8 is the 32/64 bit instruction set of ARM company. The current processors are all the products of this instruction set.

Huawei mentioned that they can design ARM processors completely independently, master core technology and complete intellectual property rights, and have the ability to develop ARM processors independently for a long time without external constraints.

Simply put, Huawei will not be affected even if ARM does not authorize the ARM instruction set to Huawei under some pressure.

On this topic, ZTE's example sounds the alarm of independent research and development. But if it is a disaster for Chinese companies to go international, it is necessary for domestic key industries to implement domestic substitution, but it is impossible to make independent innovation in everything. Ren Zhengfei, the founder of Huawei, changed his mystery a few days ago and received a lot of interviews from domestic and foreign media. He also talked about the topic of independent innovation. He said that he never supported the word "independent innovation." Science and technology are the common wealth of mankind. We must step on the shoulders of our predecessors, so as to shorten the process of entering the world leading. Everything has to be done by oneself. No one but the peasants should have this idea."
