Unformatted text preview: Mealy Machines & Design Project Password_________________ © Copyright 2009 Daniel Tylavsky Recall the block diagram of a Moore machine. Combinational Logic Input Flip-Flop Array Combinational Logic Clock Output The difference between a Mealy & Moore is: The output now changes when the INPUT changes! i.e., asynchronously! Mealy Machines & Project This changes our design procedure, specifically the state diagram. State Input(s)/Output(s) X 1 ,X 2 /Z Let’s complete a state diagram for one problem using both the Moore and Mealy approaches and compare the results. Mealy Machines & Project ✔ EX: Design a Moore & Mealy machine whose output is asserted whenever its input string has 2 1’s in sequence. Finite State Synchronous Machine Mealy or Moore Key Pad 1 Lock Unlock/ Otherwise 0, Detected Seq. Key 1, Output = Assumptions: Input Sequence = 0101101110 Output Sequence= 0000100110 Would you change this assumption? How? An external reset signal supplied on “power-up.” Mealy Machines & Project Allow overlap. State Meaning Binary Assignment...
