Mealy Vs Moore State Diagram

Here are diagrams of a Mealy state machine (left) and Moore state machine with entry and exit actions This comes down to consistency versus crude velocity.

Moore Machine The following table highlights the points that differentiate a Mealy Machine from a Moore Machine. Mealy Machine Moore Machine. So if a Mealy state has two inputs with two different outputs, you would split that one Mealy state into two states in the Moore machine where each new state’s output would match one of the two transition outputs in the Mealy machine.

For the reverse situation you would simply move the output of the state to the incoming transitions instead. The Mealy Machine can change asynchronously with the input. One of the states in the previous Mealy State Diagram is unnecessary: Note: The Mealy Machine requires one less state than the Moore Machine!

This is possible because Mealy Machines make use of more information (i.e. inputs) than Moore Machines when computing the output.

Moore Machine: Mealy machine changes its output based on its current input and present state: Output of Moore machine only depends on its current state and not on the current input: From presentation point of view, output is placed on transition Output is placed on state: Mealy will be faster, in the sense that output will change as soon as an.
