In this experiment, the application of the design principles of the state machine and the subtractor. In a state of continuous change of the digital system design using the state machine design ideas to improve the design efficiency, increase the readability of the program, reduce the error probability of the occurrence. At the same time, the state machine design is also a digital system, a most commonly used design methods. Generally speaking, the state machine can be divided into two kinds of Moore (Moore) machine, and Miriam (Mealy) machine. Moore machine, the output is only a function of the current state value, and only the arrival of the rising clock edge when the change. The Milligan machine' s output is the current state value, the function of the current output value and the current input values.
