5.3.3 [20] <5.2, 5.3> You are asked to optimize a cache design for the given references. There are three directmapped cache designs possible, all with a total of 8 words of data: C1 has 1word blocks, C2 has 2word blocks, and C3 has 4word blocks. In terms of miss rate, which cache design is the best? If the miss stall time is 25 cycles, and C1 has an access time of 2 cycles, C2 takes 3 cycles, and C3 takes 5 cycles, which is the best cache design?
There are many different design parameters that are important to a cache’s overall performance. The table below lists parameters for different directmapped cache designs.
