A CPU cache is a piece of hardware that stores frequently used data from main memory in a faster, smaller memory. This helps bridge the speed gap between processor and main memory, known as the memory wall. Cache performance is measured by metrics such as average access time (AAT) and Power law of cache misses. Stack distance profiling is also used to test the performance of the cache in terms of misses across different associativities.
