Cache

Direct Mapped Cache Cache's are directed mapped if each memory location is mapped to exactly one location in the cache. An example would be:

     location = (Block Address) MOD (Number of cache blocks in the cache)

In this way we can map a memory location to a cache location.

Example: Suppose we have a cache with 8 slots 2^3. Then a word at 45 would be found at slot 5 in the cache.
