Abstract
- In a fully associative cache, a cache line is not restricted by a cache index or cache set index and can be placed in any location. However, memory access requires searching all cache lines
Important
This approach is beneficial for very small caches, as it eliminates conflict misses by allowing data to reside anywhere within the cache, but it takes a lot more resources to locate the cache.
Just consists of 2 parts
Since each cache line isn’t restricted to a certain group of memory addresses, there is no cache set index or cache index. Therefore, the block number is the same as the tag number for a fully associative cache.
