Mealy State Diagram
February 22 2012 ece 152a digital design principles 14 mealy network example timing diagram and analysis cont output transitions occur in response to both input and state transitions glitches may be generated by transitions in inputs moore machines don t glitch because outputs are associated with present state only.
Mealy state diagram. It can be described by a 6 tuple q o δ x q 0 where q is a finite set of states. A simple mealy machine has one input and one output. The mealy machine for example 9 1 in the state diagram in figure 9 2 the numbers inside the states represented by the circles are the four states of a synchronous counter.
The mealy machine requires one less state than the moore machine. A sequence detector is a sequential state machine which takes an input string of bits and generates an output 1 whenever the target sequence has been detected in a mealy machine output depends on the present state and the external input x. Each transition edge is labeled with the value of the input shown in red and the value of the output shown in blue.
These three states are tagged within the circles as well as every circle communicates with one state. In the above figure there are three states namely a b c. Relationship with mealy machines as moore and mealy machines are both types of finite state machines they are equally expressive.
Sometimes this is indeed the case while at other times this is a reasonable abstraction many forms of state diagrams exist which differ slightly and have different semantics. The state diagram of mealy state machine mainly includes three states namely a b and c. Either type can be used to parse a regular language.
The state diagram for a moore machine or moore diagram is a diagram that associates an output value with each state. The state diagram of mealy state machine is shown in the following figure. The mealy machine can change asynchronously with the input.
The mealy machine for the state table in table 9 1 and timing diagram in figure 9 1 is shown in figure 9 2 below. This is possible because mealy machines make use of more information i e. In the above diagram the inputs and outputs are denoted with 0 0 1 0 and 1 1.
