What is the difference between moore and mealy machine?

Answer 1

Moore and Mealy state machines are the names for two types of architectures when designing a state machine. Moore state machines are controlled in such a way that the next state is dependent only on the current state. However, Mealy state machines are controlled in a way such that the next state is dependent on the current state and the state of the inputs.

A Moore state machine may require more states than a Mealy state machine to accomplish the same task, and therefore use more macrocells for state registers. The output logic of a Mealy state machine may be more complex than the output logic of an equivalent Moore state machine, and therefore use more product terms.
