Measuring & Improving Cache Performance

  • measurement and analysis of cache performance

  • look at two different techniques for improving cache performance:

    • adding associativity to the cache to reduce the miss rate

    • Use of multi-level caches to reduce the miss penalty



Reducing cache misses by more flexible placement of blocks
Reducing Cache misses by more flexible placement of blocks and write penalities are the same

  • Fully asscoative caches allow blocks to be placed anywhere in the cache

    • Have to search every tag field for every memory access

  • Set associative cache allows blocks to be placed in a fixed number of locations in the cache

    • an n-way set associative cache allows a block to be placed in one of n locations in the cache



Replacement strategies
Replacement Strategies and write penalities are the same
