7-34 Chapter 7 - Memory Calculation of Hit Ratio and Effective Access Time for Example Program Computer Architecture and Organization by M. Murdocca and V. Heuring © 2007 M. Murdocca and V. Heuring
7-35 Chapter 7 - Memory Multi-level Cache Memory As an example, consider a two-level cache in which the L1 hit time is 5 ns, the L2 hit time is 20 ns, and the L2 miss time is 100 ns. There are 10,000 memory references of which 10 cause L2 misses and 90 cause L1 misses. Compute the hit ratios of the L1 and L2 caches and the overall effective access time. H 1 is the ratio of the number of times the accessed word is in the L1 cache to the total number of memory accesses. There are a total of 85 (L1) and 15 (L2) misses, and so: (Continued on next slide.) Computer Architecture and Organization by M. Murdocca and V. Heuring © 2007 M. Murdocca and V. Heuring
