We will explore the impact of cache capacity on performance, focusing
exclusively on the data cache and excluding instruction storage in the caches. Cache access time
is directly linked to its capacity. For the sake of simplicity, let's assume that accessing the main
memory takes 100ns, and in a specific program, 50% of instructions involve data access.
Two distinct processors, denoted as P1 and P2, are engaged in executing this program. Each
processor is equipped with its own L1 cache.
L1 size L1 Miss Rate L1 Hit Time
P164 KB 3.6%1.26 ns
P2128 KB 3.1%2.17ns
(a) What is the AMAT for P1 and P2 assuming no other levels of cache?
