A Mealy machine is a finite-state machine whose output values are determined by both its current state and the current input. It is defined by a 6-tuple (Q, Σ, Δ, δ, λ, q₀) where:
In a Mealy machine, the output is determined by both the current state and the current input, allowing for immediate response to inputs. This makes Mealy machines suitable for systems where quick reactions to inputs are required.
Visualize and simulate Mealy machines with custom configurations.
| State | Input: 0 | Input: 1 | ||
|---|---|---|---|---|
| Next State | Output | Next State | Output | |
| q₀ | q₁ | 0 | q₂ | 1 |
| q₁ | q₀ | 1 | q₂ | 0 |
| q₂ | q₁ | 0 | q₀ | 1 |
A Mealy machine that performs binary addition of two input sequences. The output represents the sum bit, and the state carries the carry information.
Mealy machines are commonly used for data encoding/decoding applications where the output needs to respond immediately to input changes, such as Manchester encoding or differential encoding.
Mealy machines are often used in designing control units where control signals need to respond immediately to instruction inputs and current state.
Mealy machines are suitable for modeling communication protocols where responses (acknowledgments, error signals) must be generated immediately upon receiving specific inputs.
