MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Very fast memory compared to other computer memories. Made of SRAM types of memory. The memory circuitry doesn’t require to be refreshed to keep data. Cache memory is integrated within the processor microchip. It is a volatile memory. 30-Dec-2022

Detailed explanation-2: -Cache memory is faster than main memory. It consumes less access time as compared to main memory. It stores the program that can be executed within a short period of time. It stores data for temporary use.

Detailed explanation-3: -Cache memory is important because it improves the efficiency of data retrieval. It stores program instructions and data that are used repeatedly in the operation of programs or information that the CPU is likely to need next.

Detailed explanation-4: -Today’s CPU chips contain two or three caches, with L1 being the fastest. Each subsequent cache is slower and larger than L1, and instructions and data are staged from main memory to L3 to L2 to L1 to the processor. On multicore chips, the L3 cache is generally shared among all the processing cores.

Detailed explanation-5: -It has three main parts: a directory store, a data section, and status information. All three parts of the cache memory are present for each cache line.
