Which cache mapping is fastest?
Level 2 or Cache memory – It is the fastest memory which has faster access time where data is temporarily stored for faster access.
Is direct mapped cache faster?
These are two different ways of organizing a cache (another one would be n-way set associative, which combines both, and most often used in real world CPU). Direct-Mapped Cache is simplier (requires just one comparator and one multiplexer), as a result is cheaper and works faster.
Which cache mapping technique is better and why?
Fully Associative Mapping-\n\n A block of main memory can map to any line of the cache that is freely available at that moment. This makes fully associative mapping more flexible than direct mapping.
What are cache mapping functions?
Cache mapping refers to a technique using which the content present in the main memory is brought into the memory of the cache. Three distinct types of mapping are used for cache memory mapping: Direct, Associative and Set-Associative mapping.
