In the manufacture of the CPU need the knowledge about the functions of the CPU components used for the design the CPU. In this case, the control unit is required with a simple method of microprogramming. Microprogramming is used to create the microprogram in binary number that is used to control the CPU and Pin’s of components outside the CPU. Controller models in general are digital systems and microprocessor.
