Chinese government shifts focus from x86 and Arm CPUs, promotes RISC-V
But what about software?
China is set to introduce new policies promoting the nationwide use of open-source RISC-V chips, aiming to reduce its reliance on foreign technologies, such as x86 and Arm. Nowadays, RISC-V is often used for microcontrollers and lower-performance CPUs, but since usage of the actual ISA does not require paying licensing fees and its development is not controlled by one or two companies from the West, it is gaining traction worldwide in general and in China in particular. In 2023, some American lawmakers urged the Biden administration to limit domestic companies from working on RISC-V projects and extending the ISA, fearing China could use its open-source nature to strengthen the capabilities and performance of its processors.
