Moore Machines vs Mealy Machines

Aspect

Moore Machines

Mealy Machines

Output

Outputs depend only on the current state.

Outputs depend on the current state and input.

Number of States

Tends to require more states due to separate output behavior.

Might require fewer states as outputs are tied to transitions.

Response Time

Slower response to input changes as outputs update on state changes.

Faster response to input changes due to immediate output updates.

Complexity

Can be simpler due to separation of output behavior.

Can be more complex due to combined state-input cases.

Mealy and Moore Machines in TOC

Moore and Mealy Machines are Transducers that help in producing outputs based on the input of the current state or previous state. In this article we are going to discuss Moore Machines and Mealy Machines, the difference between these two machines as well as Conversion from Moore to Mealy and Conversion from Mealy to Moore Machines.
