![]() The instruction set is designed for a wide range of uses. ![]() Notable features of the RISC-V ISA include: instruction bit field locations chosen to simplify the use of multiplexers in a CPU, : 17 a design that is architecturally neutral, and a fixed location for the sign bit of immediate values to speed up sign extension. Its floating-point instructions use IEEE 754 floating-point. Many companies are offering or have announced RISC-V hardware open source operating systems with RISC-V support are available, and the instruction set is supported in several popular software toolchains.Īs a RISC architecture, the RISC-V ISA is a load–store architecture. Unlike most other ISA designs, RISC-V is provided under royalty-free open-source licenses. ![]() RISC-V (pronounced "risk-five", : 1 ) is an open standard instruction set architecture (ISA) based on established reduced instruction set computer (RISC) principles. ![]()
