An RV32IM processor written in Hardcaml.

The project is organized as follows:

• hard — All things related to the hardware implementation
  • arty — Build tooling and top module for the Arty A7-100T FPGA
  • cpu — Hardware agnostic CPU implementation
    • bin — Simulation, verification, and circuit compilation tooling
    • lib — CPU implementation
• soft — Software to use the CPU
  • bootloader — Shared library for the bootloader
  • offchip — Utilities for interacting with the CPU from the host operating system
    • bootloader_client — Bootloader command interface
  • onchip — Code meant to run on the CPU
    • bootloader_server — The bootloader server that runs on the CPU and waits for commands from the host
    • Various test programs that can be loaded by the bootloader to run on the CPU
  • slib — A standard library for programs running on the CPU
