2. Assume that main memory accesses take 70 ns and that memory accesses are 36% of all instructions. The following table shows data for L1 caches attached to each of two processors, P1 and P2 L1 Size 2 KiB 4 KiB L1 Miss Rate 8.0% 6.0% L1 Hit Time 0.66 ns 0.90 ns P1 P2 a) What is the AMAT for P1 and P2? Assuming a base CPI of 1.0 without any memory stalls, what is the total CPI for P1 and P2? Which processor is faster? 5 points)
