About this library

libriscv is a simple, slim and complete sandbox that is highly embeddable and configurable. It is a specialty emulator that specializes in low-latency, low-footprint emulation.

  • It's fast. Where other solutions routinely require ~50-150ns to call a VM function and return, libriscv requires 2ns.
  • It has specialized APIs that make passing data in and out of the sandbox safe and low-latency.
  • It runs on all platforms without requiring the sandbox code to be recompiled.
  • It has bindings for the Godot Game Engine
