Assume we have a computer where the clocks per instruction is 1.0 when all memory accesses hit in the cache. The only data accesses are loads and stores and these total 50% of the instructions. If the miss penalty is 25 clock cycles and the miss rate is 2%, how much faster would the computer be if all instructions were cache hits?
