Question

When showing miss rate % please explain how you got to that answer, other questions don't explain that part well and it confuses me.

Beo is il memory adies sefecene, given as word adiesces 3, 180, 43, 2, 191, 88, 190, 14, 181, 44, 186, 253 You are asked to optimize a cache design for the given references. There are three direct- mapped cache designs possible, all with a total of 8 words of data: C1 has 1-word blocks; C2 has 2-word blocks; and C3 has 4-word 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?

Explanation / Answer

Since all the references are distinct, whatever the design(c1,c2,c3) no.of misses are equal to 12.And inorder to access

c1 ,it will take 2 cycles and c2 takes 3 cycles,c3 takes 5 cycles.So the one which which having less acces time will be

the better model.So c1 is better implementation.
