3.) P1: clock rate = 700 MHz,
CPI1 = 1, CPI2 = 2, CPI3 = 3, CPI4 = 4
P2: clock rate = 850 MHz,
CPI1 = 2, CPI2 = 3, CPI3 = 2, CPI4 = 4
Consider the CPI values given in #3 and the instruction type distribution from #4 (i.e., divided equally).
At what clock rate would P1 have the same performance as the 850 MHz version of P2?
Question 1: Consider two different implementations, M1 and M2, of the same instruction set. There are four classes of instructions (A, B, C, and D) in the instruction set. M1 has a clock rate of 500 MHz while M2’s clock rate is 750 MHz. The average number of cycles for each instruction class of M1 and M2 are shown in the following table: Class CPI for this class on M1 CPI for this class on M2 A 1 2 B...
