First of all comes a benchmark for the DSTwo (a port of Linpack).
Notice that as the DSTwo uses software floating-point, floating-point operations WILL be slow. (I will try to port a benchmark which does not use floating-point later).

My apologies for reviving such an old thread, but doesn't the MIPS have an FPU? I just took a computer architecture class based on the MIPS and learned that there is a floating point unit in MIPS CPUs. I know that the MIPS has instructions to handle floating point numbers on the hardware side so I was just curious whether the SDK implemented these instructions yet. Is the MIPS instruction set for this CPU the same as what one would run in a simulator such as MARS or SPIM? Forgive me if I'm wrong about the instructions, but I was just curious about how this relates to what I learned about the MIPS in my classes this semester.asiekierka said:Here I'll post my DSTwo apps.

Thanks for the clarification. I wasn't sure which MIPS CPU this was. I'll have to read more about the chip to learn about its specific instruction set and architecture.asiekierka said:pcmantinker said:My apologies for reviving such an old thread, but doesn't the MIPS have an FPU?

You're wrong, there are tons of kinds and revisions of MIPS CPUs. This is the JZ4740 which has extra video processing instructions and possibly no floats.
