Detailed explanation-1: -Decode – Received instructions are decoded in the instruction register. This involves breaking the operand field into its components based on the instruction’s operation code (opcode). Execute – This involves the instruction’s opcode as it specifies the CPU operation required.
Detailed explanation-2: -In the decode part of the cycle, the control unit works out what the instruction is and sends signals to coordinate the other components. Lastly, during the execute part of the cycle, the instruction is executed, using the ALU if necessary.
Detailed explanation-3: -The machine cycle has four processes i.e. fetch process, decode process, execute process and store process. All these processes are necessary for the instruction execution by the processor.
