cRISC-V

This is an excercise in C to implement a RISC-V RV32I (and possibly extensions) emulator in plain C. It is aimed at being correct, (very) fast, and easy to understand.

NOTE: Currently under heavy development, expect everything to change.

Features

Current

Full 5-stage pipeline
RV32I Base Instruction Set fully implemented
Shared bus with mmio support
RAM support
ELF loading
Basic trap handling

Missing

CSR support There is no support at all for CSR

Future

M Standard Extension for Integer Multiplication and Division This is kind of a basic feature, so I think this will be implemented
