In fact, RlSC-V is an academic open source CPU. More than 100 technology companies in the world have joined the RlSC-V camp, which is more based on commercial interests and has nothing to do with "conspiracy theory" and "chess faction". The biggest revelation of RlSC-V to China is that it is not so difficult to build a technical system independent of Wintel and AA. RISC-V is pronounced RISC Five, which means the fifth generation reduced instruction processor. It was named because Professor David Patterson of Berkeley Research Group in the United States had developed four generations of reduced instruction processor chips before that.
RISC-V is not the product of national will, but the research result of University of California at Berkeley. In 20 10, Berkeley research team wanted to design a CPU. However, Intel's authorization card for X86 is very dead, the authorization card for ARM's instruction set is very expensive, and the authorization card for ARM 32 is also very strict. It seems that only four companies, including Apple and Qualcomm, have been authorized. Huawei, Spreadtrum and other companies in China have only been authorized by ARM 64.
20 10, MIPS was not acquired by imagination, SPARC was not abandoned by Oracle Bone Inscriptions, and IBM did not engage in open power. In this way, Berkeley's research team's choice is limited to DEC's vanished Alhpa, HP's PA-RISC, and An Teng, which even Intel can't push ... In this case, Berkeley's research team is very courageous and decided to design a brand-new instruction set from scratch.
