- I'm not saying that the 80MIPS is or isn't realistic, but you cannot get
- 80MIPS executing NOPS. The execution of a NOP instruction causes the
- processor to synchronize various parts of the pipeline and is one of the
- slowest instructions in the CPU. It would be wonderful if you could get NOPS
- at 80MIPS since most other instructions would be ungodly fast.
