Previously, we reported that after the acquisition of IP design vendor Innovative Logic acquired a large number of USB IP resources (such as USB 3.x), RISC-V instruction set architecture development controller and SoC leader SiFive raised $65.4 million (about Combined with 450 million yuan).

At the time, we learned that Qualcomm was an important player in the financing.

Recently, according to foreign media reports, in addition to Qualcomm, Intel and Samsung are also investing some money for the company.

X86 and ARM are the two CPU architectures we are most familiar with, but in terms of a streamlined instruction set, the open source RISC-V is also emerging.

In recent years, global attention to the RISC-V architecture has been heating up, especially China is very optimistic about it, “China RISC-V Industry Alliance” and “China Open Command Ecosystem (RISC-V) Alliance” has been It was established last year. For example, the Huangshan No. 1 processor (for wearable products) developed by Huami Company is based on RISC-V.

Some analysts say that the flexibility and openness of RISC-V is of great interest to Qualcomm. According to SiFive's current design capabilities, it takes only 1 to 3 months to develop a new RISC-V IP, and ARM chips often take 1 year or more.

It is reported that RISC-V is an open source instruction set architecture (ISA) based on the Reduced Instruction Set (RISC) principle. It can be used freely for any purpose, allowing anyone to design, manufacture and sell RISC-V chips and software without over-engineering specific micro-architectures.
