ReonV 2018 · ★ 82
One of the first RISC-V processors published from Brazil.
ReonV is a modified version of the Leon3, a synthesisable VHDL model of a 32-bit processor originally compliant with the SPARC V8 architecture, now changed to RISC-V ISA.
ReonV changed the Leon3 7-stage integer pipeline from SPARC to RISC-V, maintaining all other IP cores and resources provided by GRLIB IP Library untouched.
