"A FPGA friendly 32 bit RISC-V CPU implementation" by Charles Pappon https://github.com/SpinalHDL/VexRiscv Quote: RV32IM instruction set Pipelined on 5 stages (Fetch, Decode, Execute, Memory, WriteBack) 1.16 DMIPS/Mhz when all features are enabled Optimized for FPGA Optional MUL/DIV extension Optional instruction and data caches Optional MMU Optional debug extension allowing GDB debugging via an openOCD JTAG connection (As it's a RISC-V, there's a GCC already.) Real time OS: https://github.com/Dolu1990/FreeRTOS-RISCV Novel HDL: https://github.com/SpinalHDL/SpinalHDL Quote: SpinalHDL is a programming language to describe digital hardware and then generate the corresponding VHDL/Verilog file. No more endless wiring. Create and connect complex buses like AXI in one line. Reduce code size by a high factor, especially for wiring. Allowing you to have a better visibility, more productivity and fewer headaches. Free and user friendly IDE.
