What are the advantages and disadvantages of Mealy and Moore state machine?
Advantage and Disadvantage of Mealy and Moore state machine:
In Mealy as the output variable is a function both state and input, changes of state of the state variables will be delayed regarding to changes of signal level into the input variables, there are possibilities of glitches appearing within the output variables.
Moore overcomes glitches like output dependent onto only states and not the input signal level. All of the conceptions can be applied to Moore-model state machines since any Moore state machine can be implemented like a Mealy state machine, though the converse is not accurate.
Moore machine: the outputs are properties of states themselves... that implies that you obtain the output after the machine reaches an exacting state, or to get some output your machine has to be taken to a state that gives you the output. The outputs are held till you go to some other state
Mealy machine: Mealy machines provide you outputs instantaneously, that is instantly upon receiving input, but the output is not held after which clock cycle.
