The reason why independent research and development of mobile phone chips and operating systems is difficult is that they really have high technical content, or do they have to bypass the technology patents of foreign companies? They cannot be repeated, otherwise

It’s really technical!

Mobile phone chips are still not as good as foreign ones. There are two giants in the mobile phone chip industry, Taiwan's TSMC and South Korea's Samsung. Their chip manufacturing technology is very advanced and has reached 14nm, while domestically produced ones, For example, SMIC's latest technology is only 28nm, which is almost a whole generation behind. Technology cannot be rushed. Only by relying on bit by bit research and development, the new chip field will almost become a new one in half a year. Outdated things. In addition to cost considerations, almost all chip manufacturers will adopt the most advanced technology. Therefore, almost no one uses the old nanometer process. If no one uses it, there will be no source of income. Without income, it will not be able to support its research and development, and it will be even more impossible. If you catch up with technologically advanced manufacturers, you will only fall behind. Almost all of China's current chip factories were built by the government burning money, and there is no way to compare with the truly leading ones.

Let’s talk about chip design. PC-side chips all use the x86 architecture. This architecture is widely adapted to operating systems around the world, such as windows, linus, os x, etc. This kind of The architecture is only owned by a few manufacturers authorized by Intel, such as AMD, Texas Instruments, Micron, etc., and there are no other companies, such as the domestic Loongson and others. Even if the research and development and chip manufacturing can keep up, the performance is barely It is sufficient, but the architecture is not x86, so it cannot use Windows, it cannot be widely used, there is no income, and it cannot keep up with research and development.

The architecture of mobile phones is mostly ARM architecture, which was developed by the British ARM company. It has the characteristics of low power consumption and is suitable for use in mobile phones. Powerful manufacturers, such as Qualcomm, Samsung, and Apple, all After buying back the ARM license, you can then add your own designs to suit your own mobile phones. Incompetent manufacturers such as MediaTek and Huawei HiSilicon Kirin directly buy the ARM public version of the architecture, and then design it yourself and add a little bit of embellishment. Soon, I used it on my mobile phone. Therefore, you can see that the performance of HiSilicon Kirin of the same generation is always not as good as that of Samsung and Qualcomm processors. This is also due to the strength of the manufacturer and the factor of monopoly. Now Samsung, Qualcomm They all have their own architecture, and Apple’s processors are also based on the ARM architecture that they bought out.
