SiFive is an American semiconductor company founded in 2015 by the Berkeley researchers who created the RISC-V instruction set, and it designs processor cores that others license and build into their own chips. Its business is an alternative to Arm: because RISC-V is an open standard rather than a proprietary architecture, customers can extend the instruction set for their own workloads without negotiating with the architecture owner, which has drawn interest from companies building custom artificial intelligence and automotive silicon. Headquartered in Santa Clara, it licenses cores to chipmakers, cloud operators and defence customers rather than manufacturing anything itself.
