Detailed explanation-1: -A CPU has the following components: Fetch – gets the next program command from the computer’s memory. Decode – deciphers what the program is telling the computer to do. Execute – carries out the requested action. Store – saves the results to a Register or Memory.
Detailed explanation-2: -During the fetch execute cycle, the computer retrieves a program instruction from its memory. It then establishes and carries out the actions that are required for that instruction. The cycle of fetching, decoding, and executing an instruction is continually repeated by the CPU whilst the computer is turned on.
Detailed explanation-3: -To execute an instruction, the processor copies the instruction code from the program memory into the instruction register (IR). It can then be decoded (interpreted) by the instruction decoder, which is a combinational logic block which sets up the processor control lines as required.
