| 5 | |
| 6 | Two executables cover simulation of both Xtensa endian options, |
| 7 | ``qemu-system-xtensa`` and ``qemu-system-xtensaeb``. Two different |
| 8 | machine types are emulated: |
| 9 | |
| 10 | - Xtensa emulator pseudo board \"sim\" |
| 11 | |
| 12 | - Avnet LX60/LX110/LX200 board |
| 13 | |
| 14 | The sim pseudo board emulation provides an environment similar to one |
| 15 | provided 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 | |
| 21 | The 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 |
