The presentation discusses cache memory, highlighting its role as a temporary storage component that improves data retrieval efficiency for computer processors. It covers topics such as the memory hierarchy, different cache levels, and various cache mapping techniques including direct, associative, and set associative mapping. The presentation aims to provide an overview of the principles and structure of cache memory.

3.  Cache memory is a chip-based computer
component that makes retrieving data from
the computer's memory more efficient.
 It acts as a temporary storage area that the
computer's processor can retrieve data from
easily.

10. Cache organization:

11. Cache mapping technique:
Cache mapping is a technique by which the contents of main memory are brought into the cache
memory.
– Direct mapping
– Associative mapping
– Set associative – mapping
The following diagram illustrates the mapping process-
