Does anybody know if there is a open source MIPS instruction set simulator (in C++ or SystemC preferably)? I googled dozens of links and there is just no open ISS of MIPS cpu. Then only ones I know for now is Plasma CPU, which implements only a limited number of mips instructions, thus some application code can not be simulated by it. Gem5, which I was not able to use to boot a linux image(though followed every instruction on its web) So, do you have some experience about this?

Instruction set simulator(SystemC) for MIPS architecture

Does anybody know if there is a open source MIPS instruction set simulator (in C++ or SystemC preferably)?

I googled dozens of links and there is just no open ISS of MIPS cpu. Then only ones I know for now is

Plasma CPU, which implements only a limited number of mips instructions, thus some application code can not be simulated by it.
Gem5, which I was not able to use to boot a linux image(though followed every instruction on its web)

So, do you have some experience about this?

Have you looked at QEMU? I use it in my ELLCC project to do both Linux user mode and bare system mode emulation for the Mips.
