RISC-V Free and Open RISC Architecture
RISC-V is a free and open ISA enabling a new era of processor innovation through open standard collaboration. The RISC-V ISA delivers a new level of free, extensible software and hardware freedom on architecture, paving the way for the next 50 years of computing design and innovation.
(In March 2021, Wave Computing announced that the development of the MIPS architecture has ceased. The company has joined the RISC-V foundation and future processor designs will be based on the RISC-V architecture)
