Introduction

TinyEMU is a system emulator for the RISC-V and x86 architectures. Its purpose is to be small and simple while being complete.

Main features:

• RISC-V system emulator supporting the RV128IMAFDQC base ISA (user level ISA version 2.2, priviledged architecture version 1.10) including:
  • 32/64/128 bit integer registers
  • 32/64/128 bit floating point instructions (using the SoftFP Library)
  • Compressed instructions
  • Dynamic XLEN change
• x86 system emulator based on KVM
• VirtIO console, network, block device, input and 9P filesystem
• Graphical display with SDL
• JSON configuration file
• Remote HTTP block device and filesystem
• Small code, easy to modify, few external dependancies
• Javascript version running Linux and Windows 2000.
