Challenge Problems
Push your limits with advanced challenges
Given a processor with a clock rate of 4 GHz and an L1 cache miss rate of 2%, calculate the total effective CPI for a workload with 100,000 instructions when invoking an L2 cache that reduces the L1 miss penalty from 400 cycles to 20 cycles.
💡 Hint: Calculate the contributions from L1 misses and compare with the reduced miss penalty from L2.
You are designing a new CPU architecture with three levels of cache. Which specific features would you prioritize for each cache level to ensure optimal performance, and how would you justify your design decisions?
💡 Hint: Consider user expectations and scenarios where faster processing is essential.
