The serial adder is a digital circuit in which bits are added a pair at a time.
Let A and B be two unsigned numbers to be added to produce Sum = A + B. In this we are using three shift registers which are used to hold A, B and Sum. Now in each clock cycle, a pair of bits is added by the adder FSM and at the end of the cycle, the resulting sum is shifted into the Sum register.Mealy type FSM for serial adder:N Bit Adder Verilog
Let G and H denote the states where the carry-in-values are 0 and 1. Output value s depends on both the state and the present value of inputs a and b.
In state G and H:Input valuationOutput (s)State000FSM will remain in same state G01,101FSM will remain in same state G110FSM moves to state H01,100FSM will remain in same state H111FSM will remain in same state H001FSM moves to state G
A single Flip-Flop is needed to represent the two states. The next state and output equations are:
Y = ab + ay + by 7 zip download for mac.
s = a ⊕ b ⊕ y
The flip-flop can be cleared by the Reset signal at the start of the addition operation.Moore type FSM for serial adder:
In a Moore type FSM, output depends only on the present state. 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. Therefore we will four states namely: G0, G1, H0 and H1.
The next state and output equations are:
Y1 = a ⊕ b ⊕ y2
Y2 = ab + by2 + by2
s = y14 Bit Ripple Adder Verilog
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.Bcd Adder Verilog
