3Xtensa System emulator
4----------------------

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
