Apple-CORE has refined the D-RISC processor design previously designed at the University of Amsterdam, and grouped multiple D-RISC cores together to form Microgrids. More details available here.

Apple-CORE has produced an FPGA prototype of a D-RISC core called UTLEON3. Simultaneously, the project also produced a variety of programming tools to target Microgrids.
Apple-CORE has inspired multiple projects and forked into new initiatives:
