The state diagram for a Mealy machine associates an output value with each transition edge, in contrast to the state diagram for a Moore machine, which associates an output value with each state. When the input and output alphabet are both Σ , one can also associate to a Mealy automata a Helix directed graph [ clarification needed ] ( S × Σ ...
The algorithmic state machine (ASM) is a method for designing finite-state machines (FSMs) originally developed by Thomas E. Osborne at the University of California, Berkeley (UCB) since 1960, [1] introduced to and implemented at Hewlett-Packard in 1968, formalized and expanded since 1967 and written about by Christopher R. Clare since 1970.
As Moore and Mealy machines are both types of finite-state machines, they are equally expressive: either type can be used to parse a regular language.. The difference between Moore machines and Mealy machines is that in the latter, the output of a transition is determined by the combination of current state and current input (as the domain of ), as opposed to just the current state (as the ...
The HDL code then undergoes a code review, or auditing. In preparation for synthesis, the HDL description is subject to an array of automated checkers. The checkers report deviations from standardized code guidelines, identify potential ambiguous code constructs before they can cause misinterpretation, and check for common logical coding errors ...
UML state machines have the characteristics of both Mealy machines and Moore machines. They support actions that depend on both the state of the system and the triggering event, as in Mealy machines, as well as entry and exit actions, which are associated with states rather than transitions, as in Moore machines.

George H. Mealy (December 31, 1927 – June 21, 2010 in Scituate, Massachusetts) [1] was an American mathematician and computer scientist who invented the namesake Mealy machine, a type of finite state transducer.
An ABEL HDL description of a 4-bit counter. The Advanced Boolean Expression Language (ABEL) is an obsolete hardware description language (HDL) and an associated set of design tools for programming programmable logic devices (PLDs). It was created in 1983 by Data I/O Corporation, in Redmond, Washington.
A Mealy machine can be used as a cryptographic machine. Given an alphabet A, it is said to be possible to process a word from this alphabet into a word from alphabet B if there exists a Mealy machine which does this. Using mathematical notation, M - Mealy machine, -> - to process: thus a tuple (M, ->).
