1.. _Xtensa-System-emulator: 2 3Xtensa System emulator 4---------------------- 5 6Two executables cover simulation of both Xtensa endian options, 7``qemu-system-xtensa`` and ``qemu-system-xtensaeb``. Two different 8machine types are emulated: 9 10- Xtensa emulator pseudo board \"sim\" 11 12- Avnet LX60/LX110/LX200 board 13 14The sim pseudo board emulation provides an environment similar to one 15provided by the proprietary Tensilica ISS. It supports: 16 17- A range of Xtensa CPUs, default is the DC232B 18 19- Console and filesystem access via semihosting calls 20 21The Avnet LX60/LX110/LX200 emulation supports: 22 23- A range of Xtensa CPUs, default is the DC232B 24 25- 16550 UART 26 27- OpenCores 10/100 Mbps Ethernet MAC 28
