With a perfect cache
CPIbase = 1.5
1.4 MemAccess / instruction
Compare two 128 KB caches
64-byte blocks
Miss penalty = 60 ns
Cache 1:
Direct mapped
Miss rate = 2.1%
CC(1-way) = 0.30 ns
HT = 1 CC(1-way)
Cache 2:
2-way set associative
CC(2-way) = 1.30 CC(1-way)
Miss rate = 1.9%
HT = 1 CC(2-way)
Question: What is CPU_Time of system with Cache 2 (2-way set associative)? Choose the closest value. - 2.18 x IC
- 2.21 x IC
- 2.33 x IC
- 2.47 x IC
- 2.49 x IC
