Aren't both approaches same? It's just, when we miss we also consider the access time of previous level. 0 votes 0 votes Satbir commented Feb 2, 2019 reply Follow Share They have given hit time instead of hit rate. Avg access time = H1T1 + M1 ( H2(T1+T2) + M2(T1+T2+memory)) hit time of L1 = H1T1 = 1 cc miss rate of L1 =M1= 320/2000 = 0.16 hit time of L2 = H2(T1+T2) = 10 cc miss rate of L2 = M2 = 150 /320 miss penalty of L2 = (T1+T2+memory) = 300 cc 0 votes 0 votes Please log in or register to add a comment.
