Cache memory with associative memory
WebA direct-mapped cache maps each memory location to one location in the cache. This associativity does not require a replacement policy since there is only one cache entry for each location in memory. A set-associative cache maps each memory location to a specified number of locations in cache. A 2-way set-associative cache has 2 blocks per … WebNov 17, 2024 · Set associative mapping, which allows a block of RAM to be mapped to a limited number of different memory cache blocks, is a compromise between the two methods of mapping. A RAM block can be placed in one of two locations in cache memory using a 2-way associative mapping method.

Whenever a data is requested, the incoming memory address a … WebTo show that a 2-way associative cache can perform better than a fully associative cache, we need a scenario where the fully associative cache suffers from frequent conflict misses due to the limited number of cache blocks available to map all memory blocks. In contrast, a 2-way associative cache can reduce the number of conflicts by allowing ...
WebApr 9, 2024 · A cache memory has a line size of eight 64-bit words and a capacity of 4K words. The main memory size that is cacheable is 1024 Mbits. Assuming that the addressing is done at the byte level, show the format of main memory addresses using 8-way set-associative mapping. WebWhat is associative cache memory? Associative Mapping – In this type of mapping, the associative memory is used to store content and addresses of the memory word. Any block can go into any line of the cache. This means that the word id bits are used to identify which word in the block is needed, but the tag becomes all of the remaining bits.
