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
