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
