Web1.10*cache access time = H*cache access time + (1-H)*main memory access time. Solving finds 1090/1100 or H to be approximately .9909, giving a hit ratio of approximately 99.1% Close to the "found" answer online, but I feel a lot better about this one. from where you get the formula: effective access time = H*cache access time + (1-H)*main ... WebSep 24, 2016 · The difference comes from when the latency of a miss is counted. If the problem states that the time is a miss penalty, it should mean that the time is in addition to the time for a cache hit; so the total miss latency is the latency of a cache hit plus the penalty.
