Set associative cache offset

WebThe answer is - Each block is 32 bytes (8 words), so we need 5 offset bits to determine which byte in each block - Direct-mapped => number of sets = number of blocks = 4096 => … Web3 Mar 2012 · A page consists in more bytes (32 if I'm correct), and accessing the single location in the cache line requires an address (the offset). So, in the fully associative …

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.
