React in the same cycle-they don't need to wait for the clock.In Mealy machines, input change can cause output change as soon as logic is done-a big problem when two machines are interconnected – asynchronous feedback may occur if one isn't careful.

- Outputs change at the clock edge (always one cycle later).

Different outputs on arcs ( n 2) rather than states ( n).Mealy machines tend to have fewer states:.Ĭomparison of Mealy machines and Moore machines Formal definition Ī Mealy machine is a 6-tuple ( S, S 0, Σ, Λ, T, G ). Mealy, who presented the concept in a 1955 paper, "A Method for Synthesizing Sequential Circuits". The Mealy machine is named after George H. 3 Comparison of Mealy machines and Moore machines.
