A Moore machine is formed by three main modules:

1. Next State Combinational Logic
   • Determines the next state based on the current state (and sometimes inputs).
2. State Register (Sequential Logic)
   • Stores the current state.
   • Updates on every clock edge.
3. Output Combinational Logic

State Diagram

• Unlike the state diagram of a Mealy Machine, the Moore machine shows the output inside each state block.
• This indicates the output is not directly related to the input.
• Only the inputs are written on the arrows, showing conditions for state transitions.
