WebIf the cache organization is such that the 'SET' address identifies a set of '4' cache lines, the cache is said to be 4-way set associative and so on and so forth. Example: 2-way set associative cache: Let us take an example of a very small cache: Full address = 16 bits: Memory size = 0.5 KB Cache line = 32 bytes (256 bits). WebSet-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.

Web24 Feb 2024 · Set-associative mapping allows that each word that is present in the cache can have two or more words in the main memory for the same index address. Set associative cache mapping combines the best of direct and associative cache mapping techniques. In set associative mapping the index bits are given by the set offset bits. Web8 Nov 2024 · An n-way set associative cache is a cache that is chopped up in sections called sets. And each set can hold n-blocks. A cache-address can be broken up up in 3 parts. the offset within the block the index that identifies the set the tag that identifies the block in the set.

Web16 Oct 2024 · Set-associative cache is a specific type of cache memory that occurs in RAM and processors. It divides the cache into between two to eight different sets or areas. Data is stored in them all, but the cache distributes it to each set in sequence, rather than … WebThe cache set to which a certain main memory block can map is basically given as follows: Cache set number = ( Block Address of the Main Memory ) Modulo (Total Number of sets present in the Cache) For Example. Let us consider the example given as follows of a two-way set-associative mapping: In this case, k = 2 would suggest that every set ...

Webc. Assume a four-way set-associative cache with a tag field in the address of 9 bits. Show the address format and determine the following parameters: number of addressable units, number of blocks in main memory, number of lines in set, number of sets in cache, number of lines in cache, size of tag. Answer: WebN-Way Set Associative Cache. Another sort of cache is the N-way set associative cache. This sort of cache is similar to direct mapped cache, in that we use the address to map the address to a certain cache block. The important difference is that instead of mapping to a single cache block, an address will map to several cache blocks.

WebThe set associative cache operates in a fashion somewhat similar to the direct-mapped cache. Bits from the line address are used to address a cache directory. However, now there are multiple choices: two, four, or more complete line addresses may be present in the directory. Each of these line addresses corresponds to a location in a sub-cache.

WebSet associative caches are described as "N-Way set associative." An 8-way SA cache with 4 blocks per set has a total of 32 blocks.
