A tiny, single-file, header-only RISC-V RV32IMA emulator written in ~400 lines of dependency-free C, capable of booting Linux (RV32-NOMMU). It includes a small demo CLI wrapper with UART, SYSCON, DTB, and kernel image loading.

Use cases

• emulate risc-v rv32 in c
• boot linux on a minimal risc-v emulator
• embed a risc-v cpu emulator in my application
• learn how to write a cpu emulator
• run risc-v binaries without qemu
• port a risc-v emulator to embedded or weird platforms

When to choose

• you need a tiny, embeddable, dependency-free RISC-V emulator in C
• you want to experiment with RV32-NOMMU Linux
• you want readable, hackable emulator source to learn from

When to avoid

• you need full RV32 spec compliance, MMU, or multiprocessor support
• you need maximum emulation performance (QEMU is faster)
• you need RV64 or userspace-complete supervisor emulation
