WebIn the direct-mapped cache, 0 and 4 map to block 0, while 2 maps to block 2. Accesses to 0 and 4 miss because they conflict in block 0, but the second access to 2 hits. The hit rate is 1/5. With a 2-way set-associative cache, all three address map to the first set. Thus after the first two misses, 4 kicks out 0, 0 kicks out 2, and 2 kicks out 4. crossword pixels

Depending on the size of a cache, it might hold dozens, hundreds, or even thousands of cache lines. In a direct-mapped cache, each cache line is independent of all the others and contains two important types of information: a cache data block and metadata.

Web3. Two way Set Associative Mapping Address Structure: In set associative mapping, the cache lines are grouped together in sets. A main memory block is direct mapped to a particular set, but within the set it can map to any cache line. In this case, we have 2 cache lines in each set since it is 2-way Set associative mapping.
