 summary RISC-V (pronounced "risk-five") is an open instruction set architecture (ISA) based on established reduced instruction set computing (RISC) principles. In contrast to most ISAs, the RISC-V ISA can be freely used for any purpose, permitting anyone to design, manufacture and sell RISC-V chips and software. While not the first open ISA, it is significant because it is designed to be useful in modern computerized devices such as warehouse-scale cloud computers, high-end mobile phones and the smallest embedded systems. Such uses demand that the designers consider both performance and power efficiency. The instruction set also has a substantial body of supporting software, which fixes a usual weakness of new instruction sets. The project began in 2010 at the University of California, Berkeley, but many contributors are volunteers and industry workers outside the university. The RISC-V ISA has been designed with small, fast, and low-power real-world implementations in mind, but without over-architecting for a particular microarchitecture style. As of May 2017, version 2.2 of the userspace ISA is fixed and the privileged ISA is available as draft version 1.10.
