Sequential Design
Mealy Machine
A finite state machine where outputs depend on both current state and current inputs.
Detailed Explanation
Mealy machines produce outputs based on state-input combinations, not just state. This means outputs can change mid-state when inputs change, potentially responding faster than Moore machines (which only change outputs on state transitions).
The output logic combines state registers with input signals combinationally. This creates a path from inputs to outputs that must be considered for timing. Mealy machines often require fewer states than equivalent Moore machines.
