[MTL]The Goddess Signed In For a Year, and I Turned Over

The early Unix was a cheap or free license, and then the fee-based license was restored. Linvx was inspired by the influence of Unix, and then it was born.

As the oldest system, unix and unix systems derived from it occupy a huge majority of the market in workstations, servers, minicomputers, mainframes, and supercomputers.

Among them, the mad computer operating system and ios system developed by the fruit company also belong to the type of unix system.

The remaining part of the market share is occupied by the open source linux system, and part is occupied by the win-server system developed by Microsoft.

Linux is a completely open source operating system, but strictly speaking, it should be an open source system kernel. Any individual and organization can modify it, including commercial applications.

Therefore, most of the self-developed systems developed by individuals, enterprises, and institutions in the world are all developed on the Linux kernel.

Including Google's Android, which is also developed based on the Linux kernel.

Among the most famous large computer operating systems in the world, the unix system of Bell Labs, the win system of Microsoft Corporation, and the mad system of Fruit Company are all affiliated to the United States. The Linux open source system is the only choice for most independent developers.

Of course, in addition to the above four operating systems, there are also four mainstream chip architectures with the most widespread applications in the world.

The first is the X86 architecture, which belongs to the Faza instruction set. It was developed by the American Intel company. At present, it is basically no longer authorized to the outside world, and it occupies an absolute dominant position in the field of personal computers.

Then there is the aim architecture, which is a streamlined instruction set, developed by the aim company of Yingguo, and has been fully popularized with the help of the two major mobile phone systems of Android and Fruit, and it has a dominant position in the field of mobile chips.

The authorization method of the framework is fee-based, and there are three different levels of authorization modes.

The A-series mobile phone chips developed by Fruit Company, the Fire Dragon chip under Gaotong, the Wanwan Lianfa Branch chip, the Hunter seat chip developed by Sansang, and the entire Haisi Peninsula under Warwick all use the aim architecture.

The third is the mips chip architecture, which belongs to the streamlined instruction set and belongs to the United States. However, their company's operating conditions are not ideal, which has led to the decline of the mips architecture.

Therefore, the current Huaguo Linglongxin adopts the mips chip architecture. If they hadn't been doing it all the time, the commercial development of mips would have ceased.

The fourth is the risc-v architecture, which is also a streamlined instruction set, but its developer is also the U.S. University Berkeley Branch, which also belongs to the U.S.

The risc-v architecture itself, like the Linux system kernel, is completely open source, and any individual and organization can modify it on its basis, including commercial use.

In view of a series of control reasons in the United States, most mainstream operating systems and chip architectures are reluctant to open authorization to China, or to stop authorization at any time, leading to stuck neck situations at any time.

Huaguo has also made some solutions, that is, a domestic system based on the linux kernel and a domestic chip using mips and risc-v chip architecture to replace the "lack of cores and less souls".
