RISC-V (pronounced “risk-five”) is an open, free ISA enabling a new era of processor innovation through open standard collaboration. Born in academia and research, 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.
A RISC-V microprocessor can be configured in several architectural modes depending upon the target market and applications. Further, each microprocessor implementation can have different micro-architectural parameters depending upon performance, and power considerations. Examples of such micro-architectural parameters are cache sizes, the use of branch prediction, result forwarding, and pre-fetch to name a
