Pronounced RISK-Five, RISC-V is the latest implementation of the MIPS architecture, in an open source configuration. The project kicked off in 2010 at the University of California, Berkeley.

It had been announced in 2018. Multiple companies now offer RISC-V chips, and the architecture is compatible with several FPGA's. The RISC-V architecture is making inroads on the popular ARM embedded architecture.

There have been numerous space missions using the MIPS architecture. One of these, New Horizons, is currently sending back data from outside our solar system. The big problem is radiation damage to electronics. RISC-V has a solution to this.
