Cache Performance The table below lists three different cache configurations for a processor with a single level of cache and their associated miss rates. Assume that the base CPI for the processor is 2.0 and that the cache miss penalty, in number of CPU clock cycles, is computed by the following formula: Miss rate = (5 + block size in bytes) * 2.5 The processor executes a program in which 38% of the instructions contain data references. (a) Determine the effective (or actual) CPI for the three cache configurations. (b) Which cache configuration results in the best processor performance
