Challenge Problems
Push your limits with advanced challenges
Given a scenario where a CPU is set to run with a L1 cache miss rate of 1% and an L2 miss rate of 0.5%, compute the effective CPI assuming main memory access incurs a 500-cycle penalty.
💡 Hint: Break down the hits and misses separately for accurate calculations.
Design a multi-level cache system for a hypothetical CPU. Discuss the decisions made regarding cache size, types, and structure while considering speed and miss rates.
💡 Hint: Think about typical loads and access patterns in a system during peak times.
