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
