Performance of caches - computer architecture, Computer Engineering

Performance of caches:

      Amdahl's Law regarding overall speed up:

             Alternatively, CPU stall can be considered:                                                                  

CPU execution time =( CPU clock cycle + Memory stall cycle)*clock cycle

The number of memory stall cycle depends:

Memory stall cycle=IC * Memory reference per instruction *Miss rate *Miss penalty
