Question

Assume that the access time to main memory is 100 ns and the clock rate is 4 GHz. The miss rate per instruction at the primary cache is 10%, and the local miss rate is 5% at the secondary cache. The hit times for L1 and L2 caches are 0.25 ns and 5 ns, respectively. If there is no memory reference instruction, calculate the AMAT and total CPI for this processor when the base CPI is 1.0 without any memory stalls.

Step 1

Calculate the miss penalty for L1 cache: Miss penalty = L2 access time + L2 miss rate * L2 access time Miss penalty = 5ns + 5% * 5ns Miss penalty = 5.25ns Show more…
