Why did X86 and ARM become the mainstream CPU ecosystem? Expert: Spend money to implement other standard specification source code
Bao Yungang said that now X86 and ARM have become two mainstream processor ecosystems.The key reason is not that Intel,AMD, ARM, these international processor head companies control the formulation of the X86 and ARM instruction set specifications(Counter example: IBM controls the PowerPC instruction set, SUN controls the SPARC instruction set, and DEC controls the Alpha instruction set).
More importantly, they invest heavily in R&D on the source code implementation of other standard specifications,To make it more compatible with X86 and ARM processors, for example, Intel has invested heavily in standard specifications such as PCIe, Ethernet, SATA, and open source software such as Linux.
It is known that,When X86 and ARM competed for the market, the open source RISC-V architecture rose and became the third largest CPU architecture.At the same time, 10 billion cores have been shipped in the past few years.
On August 24, Academician Ni Guangnan said in his speech at the 2022 RISC-V China Summit: “At present, the mainstream CPU market is still monopolized by the X86 and ARM architectures, but the emerging open source instruction set RISC-V will provide new opportunities for the development of my country’s chip industry. , if you seize the opportunity, it is possible to take the initiative in CPU core technology.”
