WebSet associativity An intermediate possibility is a set-associative cache. —The cache is divided into groups of blocks, called sets. —Each memory address maps to exactly one set in the cache, but data may be placed in any block within that set. If each set has 2x blocks, the cache is an 2x-way associative cache. In a direct-mapped cache structure, the cache is organized into multiple sets with a single cache line per set. Based on the address of the memory block, it can only occupy a single cache line. The cache can be framed as a n × 1column matrix. See more In a fully associative cache, the cache is organized into a single cache set with multiple cache lines. A memory block can occupy any of the cache lines. The cache organization can be … See more Other schemes have been suggested, such as the skewed cache, where the index for way 0 is direct, as above, but the index for way 1 is formed with … See more Set-associative cache is a trade-off between direct-mapped cache and fully associative cache. A set-associative cache can be imagined as a n × mmatrix.
