A nonpipelined processor has a clock rate of 2.5 GHz and an average CPI (cycles per instruction) of 4. An upgrade to the processor introduces a five-stage pipeline. How- ever, due to internal pipeline delays, such as latch delay, the clock rate of the new processor has to be reduced to 2 GHz. a. What is the speedup achieved for a typical program? b. What is the MIPS rate for each processor?

ever, due to internal pipeline delays, such as latch delay, the clock rate of the new
processor has to be reduced to 2 GHz.
