Chapter 5, Problem 5.7.5E

Explanation of Solution

Performance:

Yes”, it is possible to have an even greater cache hierarchy than two levels so it provides better performance.

Calculation:

Given:

Processor speed = 2GHz

Main memory access time = 100ns

First-level cache miss rate = 7%

Second-level cache = 12 cycles

Second-level cache miss rate = 3.5%

Third-level cache = 50 cycles

Base CPI = 1.5

Memory miss cost = Processor speed + Main memory access                             = (× 109) × (100 × 109)                             = 200 cycles

Total CPI = (Base CPI) + (second level cache × first level miss rate) +                    (third level cache × second level miss rate) + (memory miss cost × 1
