Behaviour of Memory Hierachies
Compulsory Misses: first access to the page (block) results in a fault (miss).
- so increase page (block) size
Capacity misses: memory (cache) cannot contain all virtual addresses (main memory).
- so increase size of memory (cache)
Collision misses: direct mapping causes several pages (blocks) to be mapped to one physical page (cache index).
- so use fully associative mapping.
