Associative Mapping:

It is a more flexible mapping technique

• A primary memory block can be placed into any specific cache block position.
• Space in the cache may be used more efficiently, but require to search all 128 tag patterns.

 Set-Associate Mapping

Combination of the - associative and direct mapping technique

• Blocks of the cache are combined into sets, and the mapping permit a block of the primary

memory to reside in any  particular block of a specific set.

Note: Memory blocks 0, 64, 128,..., 4032 maps into cache set 0.
