Announced back in 2019 was the OpenPOWER Microwatt FPGA Soft CPU Core. OpenPOWER's Microwatt is a VHDL-based design for an open-source POWER ISA processor. core. The Microwatt is a basic 64-bit POWER core that can be run for software simulations or on FPGA hardware. But now Microwatt will actually see chip fabrication thanks to a program sponsored by Google...
