Set associative cache example 315
Web27 Jul 2024 · A set-associative cache that includes k lines per set is known as a k way set-associative cache. Because the mapping approach uses the memory address only like direct mapping does, the number of lines included in a set should be similar to an integer power of two, for example, two, four, eight, sixteen, etc.

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 framed as 1 × mrow matrix.
