Question

Explain memory hierarchy and also explain various cache mapping techniques

Answer 1

Memory hierarchy affects performance in computer architectural design, algorithm predictions, and lower level programming constructs involving locality of reference. Designing for high performance requires considering the restrictions of the memory hierarchy, i.e. the size and capabilities of each component.
CACHE MAPPING TECHNIQUES.— Cache mapping is the method by which the contents of main memory are brought into the cache and referenced by the CPU. The mapping method used directly affects the performance of the entire computer system.
