| 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 |
