The only difference between circuits of Mealy and Moore type FSM for serial adder is that in Moore type FSM circuit, output signal s is passed through an extra flip-flop and thus delayed by one clock cycle with respect to the Mealy type FSM circuit. ![]() The control circuit uses a 5-bit counter, which outputs a signal K 1 when. The two 3-bit inputs are given serially into a 3-bit. ![]() S = y 1 Fig: State table for the Moore type serial adder FSM Fig: State-assigned table for the Moore type serial adder FSM Fig: Circuit for Moore type serial adder FSM (a) Figure shows the block diagram for a 32-bit serial adder with accumulator. The objective of this project is to design, simulate & layout a 3-bit serial adder with accumulator. Fig: State Diagram for Moore type serial adder FSM Therefore we will four states namely: G 0, G 1, H 0 and H 1. Since in both states, G and H, it is possible to produce two different outputs depending on the valuations of the inputs a and b, a Moore type FSM will need more than two states. In a Moore type FSM, output depends only on the present state. ![]() The flip-flop can be cleared by the Reset signal at the start of the addition operation.
