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
