| MIPS System emulator | |
| -------------------- | |
| Four executables cover simulation of 32 and 64-bit MIPS systems in both | |
| endian options, ``qemu-system-mips``, ``qemu-system-mipsel`` | |
| ``qemu-system-mips64`` and ``qemu-system-mips64el``. Five different | |
| machine types are emulated: | |
| - The MIPS Malta prototype board \"malta\" | |
| - An ACER Pica \"pica61\". This machine needs the 64-bit emulator. | |
| - A MIPS Magnum R4000 machine \"magnum\". This machine needs the | |
| 64-bit emulator. | |
| The Malta emulation supports the following devices: | |
| - Core board with MIPS 24Kf CPU and Galileo system controller | |
| - PIIX4 PCI/USB/SMbus controller | |
| - The Multi-I/O chip's serial device | |
| - PCI network cards (PCnet32 and others) | |
| - Malta FPGA serial device | |
| - Cirrus (default) or any other PCI VGA graphics card | |
| The Boston board emulation supports the following devices: | |
| - Xilinx FPGA, which includes a PCIe root port and an UART | |
| - Intel EG20T PCH connects the I/O peripherals, but only the SATA bus | |
| is emulated | |
| The ACER Pica emulation supports: | |
| - MIPS R4000 CPU | |
| - PC-style IRQ and DMA controllers | |
| - PC Keyboard | |
| - IDE controller | |
| The MIPS Magnum R4000 emulation supports: | |
| - MIPS R4000 CPU | |
| - PC-style IRQ controller | |
| - PC Keyboard | |
| - SCSI controller | |
| - G364 framebuffer | |
| The Fuloong 2E emulation supports: | |
| - Loongson 2E CPU | |
| - Bonito64 system controller as North Bridge | |
| - VT82C686 chipset as South Bridge | |
| - RTL8139D as a network card chipset | |
| The Loongson-3 virtual platform emulation supports: | |
| - Loongson 3A CPU | |
| - LIOINTC as interrupt controller | |
| - GPEX and virtio as peripheral devices | |

| ~~~~~~~~~~~~~~~~~~~~~~~~ | |
| Executable ``qemu-system-mipsel`` also covers simulation of 32-bit | |
| nanoMIPS system in little endian mode: | |
| - nanoMIPS I7200 CPU | |
