2 cards from this section. Quick, good the night before a test.
What does L1 stand for in caching systems?
Think about the first level of memory storage that interacts with the CPU.
What is the purpose of a cache?
Why does the CPU need a faster alternative to main memory?
What is the role of L1 cache?
Think about what lies closest to the CPU for quick access.
True or False: L2 cache is faster than Main Memory.
Consider caching speed order from fastest to slowest.
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.
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.
Think about typical loads and access patterns in a system during peak times.
