What is a cache miss?
💡 Hint: Think about the conditions that lead to accessing main memory.

Challenge Problems
Push your limits with advanced challenges
Given a CPU architecture with a base CPI of 2, a miss rate of 1.5% for L1 cache with a miss penalty of 300 cycles, calculate the new effective CPI after adding L2 cache with a reduced miss rate of 0.5% with a 50 cycle penalty.
💡 Hint: Apply the effective CPI calculation for both levels with penalties.
Discuss the implications of a very high miss rate on CPU performance and how cache design might be adjusted to mitigate this issue in a multi-level cache architecture.
💡 Hint: Refer to trade-offs discussed in cache design.
