	Mealy machine - Wikipedia, the free encyclopedia
		In the theory of computation, a Mealy machine is a finite state machine where the outputs are determined by the current state and the input.
		In contrast, the output of a Moore finite state machine depends only on the current state and does not depend on the current input.
		However, every Mealy machine is equivalent to a Moore machine whose state is the Cartesian product of the Mealy machine's current and previous states.

		States, Transitions, and Outputs in Mealy and Moore Machines Suppose that a given state machine has M inputs and N outputs and is being implemented using L flip-flops.
		In the Moore machine, the maximum is the smaller of the number of states, 2L, and the number of possible output patterns, 2N.
		Synchronous Mealy Machines The glitches in the output in Figure 8.34 are inherent in the asynchronous nature of the Mealy machine.

	Mealy and Moore Finite State Machines - for ECE221
		Both kinds of machines consist of flip-flop whose inputs are logical combinations of the input signals and the values of the flip-flop Q and Q' outputs.They differ in how the outputs of the machine are determined.
		In the figure, we see that the output of a Moore machine is associated with the state itself, whereas with a Mealy machine the output is associated with both the state the machine is now in and the current values of the inputs.
		Because this is a Moore machine the output is noted inside the state itself.

		Moore was the first to clearly define this type of finite state automata, so we describe such machines as Moore machines.
		In the state diagram for a Mealy machine, each arc (state transition) is labeled with the input that enables that transition, a slash, and the output that is associated with that transition.
		The output associated with each state in a Moore machine is written inside the circle for that state, under the state name, separated by a slash.

	Mealy and Moore State Machines (Site not responding. Last check: 2007-10-08)
		Some machines have the rather convenient property that all the transitions entering a given state are assigned the same output value.
		The difference between Mealy and Moore machines may at first appear to be minor, however there are significant differences between the design processes of each state machine.
		When a beginning state is chosen in a Mealy machine, the output sequence is undefined until the first transition occurs, while, defining the initial state in a Moore machine determines directly the first symbol of the output sequence.

	Finite State Machines with Output (Mealy and Moore Machines)
		Given the Moore machine in the previous diagram, and the timing diagram below, you might be asked to determine the state and output.
		It means that given a Moore machine, you can create a Mealy machine, such that if both machines are fed the same sequence of inputs, they will both produce the same sequence of outputs.
		However, the basic idea of converting a Mealy machine to a Moore machine is to increase the number of states.

	06.04.98 Registered-output FSMs synchronize outputs to state transitions
		Finite-state machines (FSMs) in digital-logic design are generally either Mealy or Moore machines.
		The only difference between these two types of machines is that the Mealy machine forms outputs derived from the inputs and the current state, and the Moore machine forms outputs derived from just the current state.
		Because FSM registered outputs toggle at the same clock edge that transitions the machine into the associate state, analyzing the state-transition diagram is intuitive when relating it to FSM timing or sequencing during hardware debugging or simulation.

	Implementing Mealy and Moore Machines
		Recall from the Moore machine, you look at the current state, and then check what the output is from the FSM, and then copy the output bits for each occurrence of that state.
		The purpose of the ROM (or the circuit that would go in the place of the ROM) is to generate the correct control signals to the flip flops (using feedback) to get to the next state at the next positive clock edge, as well as to generate the output of the circuit.
		Implementing a Moore or Mealy machine is not that hard, especially if you don't intend to minimize the circuit (which we don't).
