coekjan / cemu

A simple emulator. Currently support RV64IMASU with Sv39 and MIPS32. Capable of booting Linux. Suitable for education and research.

CEMU

A simple full system emulator.

Easy to be used for difftest with soc-simulator.

  • RV64IMACSU
  • Sv39 MMU and TLB
  • RISC-V CLINT
  • RISC-V PLIC
  • Capable of booting S-Mode SMP Linux with OpenSBI

• MIPS32

  • MIPS Release 1 support without Branch-Likely instruction
  • TLB based MMU Support
  • Capable of booting Linux and ucore-thumips

• LoongArch32(Reduced)

  • Support LoongArch32(Reduced) instruction set, except FP instructions
  • TLB based MMU Support
  • Capable of booting Linux and ucore-loongarch32

TODO List

• Cache simulation support (Currently at out-of-tree cache branch)
