RISC-V (pronounced “risk-five”) is an open-source instruction set architecture (ISA) based on the principles of Reduced Instruction Set Computing (RISC), which can be simply explained as a type of “open-source hardware” corresponding to the open-source software movement. The project began in 2010 at the University of California, Berkeley, but many contributors are volunteers and industry … Read more
