The equation would be: I know the answer here should be 0.008 CPI, but I don't understand how to get there. fly wheels)? Question: A computer has a cache, main memory and a hard disk. These functional units are called as stages of the pipeline. If wall clock time > CPU time, you're waiting for disk, network or other devices. When trying to improve performance, look at what occurs frequently => make the common case fast. The number of functional units may vary from processor to processor. Again, CPU time is the actual time the CPU spends computing for a specific task. Since the clock rate is fixed, the number of instructions needed for the "new" P2 is 8/10 * 30 x 10^9, or 24 x 10^9. Response time also called Execution time. But if there are more important things to do, the system might spend 59 seconds not working on your task, then one thread runs for one second doing your task: One second execution time, 60 seconds response time.
