While many state machines are designed using the state diagram approach shown in Figure 1, another method of describing a state machine’s behavior is the algorithmic state chart. By considering a 4 × 4 grid of possible states based on left and right activation, in primary (sensation) and secondary (perception/comprehension) response, the range of responses is completely specified. 12 Algorithmic State Machine - 148 - The model of algorithmic state machine ASM is shown in Fig. So a Cassel 1, Falk Howar2, Bengt Jonsson , and Bernhard Ste en3 1 Dept.

A finite-state machine (FSM) or finite-state automaton (FSA, plural: automata), finite automaton, or simply a state machine, is a mathematical model of computation.It is an abstract machine that can be in exactly one of a finite number of states at any given time. The machine is viewed as the combination of Mealy and Moore machines. It is difficult to describe the behavior of large state machines using state diagrams. State-merging algorithms for learning these models can The ASM diagram is like a state diagrambut more structured and, thus, easier to understand. These machines are characterized by a behavior that is determined by a limited and defined number of states, the holding conditions for each state, and the branching conditions from one state to another. The algorithmic state machines (ASM) can be used to describe the operation of both state machines based on Moore and Mealy models, as well as of systems that have the output characteristics of both Mealy and Moore models. 4.1 Flowcharts and Algorithmic state machines 4.1.1 Example of ASM.
