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
