Also alternately referred to as Instruction cycle but it is a part of the instruction cycle.The instruction cycle is the main operation performed by the processor and it is also called as processor cycle. Whereas, the instruction cycle is the process initiated by the CPU to execute one program instruction .What Is Machine Cycle ? CPU Instruction Cycle Difference Between Instruction Cycle And Machine Cycle The instruction cycle is the process used by the processor to execute one instruction. The machine cycle is just a one step of the instruction cycle.Depending upon the complexity of the program instruction, the processor might need one or more machine cycles to execute one instruction.The processor takes minimum one and maximum four machine cycle to execute one program instruction. Whereas, one machine cycle takes twelve clock cycles. CPU Functions What Are The Functions Of CPU ? The CPU performs some of the most important functions in a computer System and these functions include : To Perform Arithmetic Calculation Operations.To Perform Logical Operations.To Control Functions Of Other Hardware Components.To Fetch the Data And Program Instructions From Main Memory.To Decode the Program Instructions.To Operate On Data As per Program Instructions.To Store Data After Processing.To Continuously Execute Instruction Cycle / Machine Cycle.
