Detailed explanation-1: -The ability of cache memory to improve a computer’s performance relies on the concept of locality of reference. Locality of reference refers to the tendency of the computer program to access the same set of memory locations for a particular time period.
Detailed explanation-2: -Traditional cache memory architectures are based on the locality property of common memory reference patterns. This means that a part of the content of the main memory is replicated in smaller and faster memories closer to the processor.
Detailed explanation-3: -Locality of reference refers to a phenomenon in which a computer program tends to access same set of memory locations for a particular time period. In other words, Locality of Reference refers to the tendency of the computer program to access instructions whose addresses are near one another.
Detailed explanation-4: -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.
Detailed explanation-5: -1. Spatial Locality : Spatial Locality means that all those instructions which are stored nearby to the recently executed instruction have high chances of execution. It refers to the use of data elements(instructions) which are relatively close in storage locations.
