In essence, it’s a 32-bit RISC ISA designed from a holistic view on integer, floating point, scalar and vector operations. In addition there is a hardware implementation of a single issue, in order, pipelined CPU. The hardware implementation mostly serves as an aid in the design of the ISA (at the time of writing the CPU is still incomplete).
Interesting project. Inspired by MIPS and the Cray-1. Far from complete, but already usable for running simple programs.http://www.bitsnbites.eu/the-mrisc32-a-vector-first-cpu-design/
