.. _Xtensa-System-emulator:
Xtensa System emulator
----------------------
Two executables cover simulation of both Xtensa endian options,
``qemu-system-xtensa`` and ``qemu-system-xtensaeb``. Two different
machine types are emulated:
- Xtensa emulator pseudo board \"sim\"
- Avnet LX60/LX110/LX200 board
The sim pseudo board emulation provides an environment similar to one
provided by the proprietary Tensilica ISS. It supports:
- A range of Xtensa CPUs, default is the DC232B
- Console and filesystem access via semihosting calls
The Avnet LX60/LX110/LX200 emulation supports:
- A range of Xtensa CPUs, default is the DC232B
- 16550 UART
- OpenCores 10/100 Mbps Ethernet MAC
