NEMU is a simple but complete full-system emulator supporting x86, mips32, riscv32, and riscv64 instruction sets, designed for teaching computer architecture. It includes a monitor with a debugger, a CPU core, memory/paging, interrupts, and simplified devices.
Use cases
- learn how a CPU emulator works by building one
- run bare-metal programs in a teaching emulator
- differential test a CPU implementation against QEMU
- study instruction sets like x86 and riscv64 hands-on
- debug guest programs with single stepping and watchpoints
- teach computer architecture with a simplified full-system emulator
When to choose
- you are a student in NJU's computer architecture course or a similar course
- you want a small, readable emulator codebase to study or modify
- you need a teaching-oriented full-system emulator for riscv32/riscv64, mips32, or x86
When to avoid
- you need a production-grade emulator with full ISA coverage and OS support
- you need floating-point instructions, protected mode, or full memory protection
- you want high performance virtualization rather than educational simulation
