Zustandsmaschin

A Zustandsmaschine, also known as a finite state machine (FSM) or state machine, is a computational model used to design both computer programs and sequential logic circuits. It consists of a finite number of states, transitions between those states, and actions or outputs associated with each state or transition. The behavior of the machine is determined by its current state and the inputs it receives.

In a Zustandsmaschine, each state represents a specific condition or mode of operation. Transitions between states occur based on specific conditions or events, which are often triggered by inputs. Each transition can also produce an output or perform an action. The machine's behavior is thus defined by the sequence of states it traverses and the actions it performs.

Zustandsmaschinen are widely used in various fields, including software engineering, hardware design, and control systems. They provide a clear and structured way to model and implement systems that exhibit sequential behavior. By abstracting the system's behavior into states and transitions, Zustandsmaschinen help in understanding, designing, and verifying complex systems.

There are different types of Zustandsmaschinen, including Mealy machines and Moore machines, which differ in how outputs are generated. Mealy machines produce outputs based on both the current state and the inputs, while Moore machines produce outputs solely based on the current state. Regardless of the type, the fundamental principles of states, transitions, and actions remain consistent.
