1.5 Steady Magnitude out of 10. Star growth looks organic. Data as of September 14, 2026.

About the project

An rv32ima RISC-V instruction set emulator with a minimal set of emulated devices capable of booting Linux. Accompanies a blog post about building a system from scratch.

Useful for

Build a minimal Linux system for RISC-V to study the bring-up process
Study the internals of an rv32ima RISC-V emulator from the C++ sources
Run the emulator in the browser via WebAssembly using the exported functions

Star trust

Growth looks organic: forks and discussion are in line with active projects, and stars arrive unevenly, the way people give them.

These are heuristics, not a verdict: we judge by the repository’s behavior, not by a list of stargazers.
