We have two computers P1 and P2. The following is the breakdown of two programs A and B.

Operation	A	B	P1 CPI	P2 CPI
Load/store	30%	50%	2	2
ALU	60%	20%	1	2
Branch	10%	30%	3	2

a) P1 has a 2Ghz speed. What is the execution time if A runs for 300 instructions? What is the execution time if B runs for 500?

b) P1 has a 2Ghz speed. What does the clock rate for P2 so that both computers take the same time to run for program A.
