There are two basic types of sequential circuits: Mealy and Moore. Because these circuits transit among a Because these circuits transit among a finite number of internal states, they are referred to as finite state machines (FSMs).

The difference between Mealy and Moore machines relies in the methods of output generation. In Moore machines, outputs are function of current state. This means that whenever state changes, the output also changes. In Mealy machines, outputs are function of both input and current state. A state machine can be divided into three parts: State register, Next-State Logic and Outputs. It is

The decision to implement a Moore or a Mealy machine will depend upon the function the state machine is required to perform along with any specified reaction times. The major difference between the two is in how the state machines react to inputs. A Moore machine will always have a delay of one clock cycle between an input and the appropriate output being set. This means a Moore machine is

As time progresses, the FSM transits from one state to another. The new state is determined by the next-state function, which is a function of the current state and input signals. In a synchronous FSM, the transition is
Hi, there is one major and important difference between these two : mealy removes glitches but Moore doesn’t. Hence mealy circuits are preferred mostly. Interviewer generally ask about this glitch issue.


As you recall, the only difference between a Mealy and a Moore FSM is that for the Mealy FSM, the output is dependent on both the current state and the input. The analysis for a Mealy
The difference between Mealy and Moore machines is in how outputs are generated. In a Moore machine, the outputs are a function of the current state.

The output from a Mealy machine is labelled on the state transitions, and depends on both the state and the input. The output from a Moore machine is associated with the state only. The machines are equivalent, as transformations can be done either way between the two machines. A Mealy machine can be converted to a Moore machine by adding states.
