![]() ![]() APPARETUS: Xillin 9. 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. EXPERIMENT 5 NAME: SHYAMVEER SINGH Roll No: B-54 REG No:11205816 AIM: Implementation of parallel adder using half adder and full adder. 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 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 code for the full adder is also shown for completeness. ![]() Remember that a module is a basic building block in Verilog. The following Verilog code shows a 4-bit adder/subtractor that uses the ripple carry method. The flip-flop can be cleared by the Reset signal at the start of the addition operation. Verilog Code for Full Subtractor using Dataflow Modeling.
