    grasshopper, we're not simulating an asteroid collision or weather patterns.
    Flops is going to be almost meaningless because the chip is just not a good fit for that.

    80 MHz / 4 clocks minimum per instruction * 8 cores = the 160 MIPS you've probably already seen.

    The documentation for the floating point object lists the execution time for each operation. From that you can calculate FLOPs. More for an add, less for a divide.

    grasshopper,
    Have you read the documentation, the Propeller Manual, the datasheet for the Propeller, the documentation for the floating point object? All that information is there, the number of clock cycles for each instruction, the approximate time each floating point subroutine takes to do its job, etc.
