Abstract

[Caches have long been a critical component of the memory hierarchy. Early work focused on using caches to reduce effective access time or latency. Later, caches were also used to reduce required memory bandwidth. In modern multicore processor systems, where the memory hierarchy accounts for a large fraction of total system energy, caches play a critical role in reducing energy as well. Caches filter out expensive off-chip memory accesses, and replace them with much cheaper cache accesses [129]. Increasing cache size can improve system performance and energy by reducing memory accesses, but at the cost of high area and power overheads at the cache level.]
