Caches - Performance

This lecture covers the performance evaluation of cache memory in computer systems. It discusses measuring performance using benchmarks like SPEC, Amdahl's law, and CPU performance equations. The memory hierarchy and cache performance indicators such as miss rate and average memory access time are explained. Cache optimizations, including the 3 Cs of cache misses and strategies to reduce misses, are detailed. Examples illustrate the impact of block size, cache size, and associativity on miss rates. The lecture concludes with insights on multilevel caches to reduce miss penalties and enhance system performance.
