N-way associative cache

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 × m matrix. The cache is divided into ‘n’ sets and each set contains ‘m’ cache lines.

Web13 mei 2024 · For a n-way set associative cache, the number of rows would be cache size divided by the number of ways and the block size, i.e. Number of rows = Cache Size / (Block Size x Number of Ways) Once the number of rows are known, the number of index bits would simply be the log base 2 of the number of rows: WebAt one extreme is a fully associative cache, in which a new line can be placed at any location in the cache. At the other extreme is a direct mapped cache, in which each cache line has a unique location in the cache to which it will be assigned. Intermediate schemes are called n-way set associative.

WebIn between these two extremes are n-way associative caches. A 2-way associative cache (Piledriver's L1 is 2-way) means that each main memory block can map to one of two cache blocks. WebSet-associative cache (2-way associative) Associativity is the size of these sets, or, in other words, how many different cache lines each data block can be mapped to. Higher associativity allows for more efficient utilization of cache but also increases the cost.

Web4 aug. 2024 · The 1024 example hits a bad case. For that entire column all words requested from RAM land in the same cell in cache (or the same 2 cells, if using a 2-way associative cache, etc).
