Question

in regards to the memory hierarchy, why does it take longer to process a miss than a hit?

Answer 1

Definition - What does Cache Miss mean?

Cache miss is where the information mentioned for processing by a part or application isn't found in the cache memory. It causes execution delays by requiring the program or application to get the information from other cache levels or the fundamental memory.

Cache miss happens inside cache memory access modes and techniques. For each new solicitation, the processor looked through the essential cache to find that information. In the event that the information isn't discovered, it is viewed as a cache miss.

Each cache miss hinders the general cycle in light of the fact that after a cache miss, the focal processing unit (central processor) will search for a more significant level cache, for example, L1, L2, L3 and irregular access memory (Smash) for that information. Further, another section is made and replicated in cache before it very well may be gotten to by the processor.
