In this execution process, it takes help of ALU, if the instruction execution involves arithmetic or logical operation (like AND, OR, Ex-OR). After execution of the current instruction, the CPU fetches the next instruction for execution. This process continues until the program is completed and the result is output using the output device. In many computers, the control unit and the ALU are integrated into a single block, known as Central Processing Unit (CPU).Central Processing Unit (CPU) consists ...
