MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -It is a memory unit placed between the CPU and main memory and is used to store instructions, data, or both.

Detailed explanation-2: -A cache memory is used by the central processing unit of a computer to reduce the average cost time or energy to access data from the main memory. Generally Cache memory is logically positioned between CPU and main memory.

Detailed explanation-3: -Cache memory is an extremely fast memory type that acts as a buffer between RAM and the CPU. It holds frequently requested data and instructions so that they are immediately available to the CPU when needed. Cache memory is used to reduce the average time to access data from the Main memory.

Detailed explanation-4: -cache memory, also called cache, supplementary memory system that temporarily stores frequently used instructions and data for quicker processing by the central processing unit (CPU) of a computer. The cache augments, and is an extension of, a computer’s main memory.

Detailed explanation-5: -A primary cache is always located on the processor chip. This cache is small and its access time is comparable to that of processor registers. Secondary cache is placed between the primary cache and the rest of the memory. It is referred to as the level 2 (L2) cache.
