Web(8 points) (cache organization) Two of the design choices in a cache are the row size (number of bytes per row or line) and whether each row is organized as a single block of data (direct mapped cache) or as more than one block (2-way or 4-way set associative). The goal of a cache is to reduce overall memory access time. Suppose that we are WebI have a 3 way set associative cache with 2 word blocks, total size of 24 words. I am given $3, 180, 43, 2, 191, 88, 190, 14, 181, 44, 186, 253$ to try to map. What I have so far and …

WebThus, there was no need for offset bits in the class example. The following exercise gives a more practical example of memory reference in a set-associative cache. However, as in the class example, only the tag and set field values are sufficient to verify the memory reference exists in the cache.
