Accessing a Cache:

 Direct mapping:

(Block address) modulo (Number of cache block in the cache)

The valid bit indicate whether an entry contain a valid address.

Initially, all valid bits are reset ("0" - not valid)

• Small fast memory + big slow memory
• Look as a larger fast memory

Address Mapping in Cache:

Miss = not hit,

Meaning is that the data has to be retrieved fr
