Question
Suppose you had a computer that, on average, exhibited the following properties on the programs that you run: Cache miss rate: 2.5% Percentage of memory instructions (load/store): 40% Miss penalty: 70 cycles There is no penalty for a cache hit (i.e. the cache can supply the data as fast as the processor can consume it). Find CPI and speed-up against CPI of CPU with the ideal cache. Compare its CPI to the CPI of CPU w/no cache.
