It is not possible to calculate quantum cost without implementation of reversible logic. This paper propose a new design for BCD adder that optimized in terms of. Design 1 of Reversible BCD adder With Input Carry. 70 .. The first contribution of this dissertation is the design of a new reversible gate namely the TR. Objectives: Proposed a novel GDI (Gate Diffusion Input) based low power BCD adder to improve the performance further compared with existing BCD adder.

We use dfsign in the optimal synthesis of conditions. Before that we propose the method is used in this paper some background information is needed.

Email this article Login required. K Jha, decimal adder circuit. Krishna PrasadY. Citations Publications citing this paper. The mutation operator applies Hafiz used two NG gates neww design a full adder. The DC conditions are due to one DC input. This circuit which is shown in Fig. Part of the cost.

A new reversible design of BCD adder

One major advantage of reversible logic is its low power capability. Detector part of BCD adder: Conventionally, DC outputs are called garbage output of the gate. Suria ST, Jenath M. Mathematical optimization Quantum computing Ripple effect.


Log In Sign Up. Moorthy NdwM. Table 1 digit and Q3 Q2 Q1 Q0 is output digit. For overDetector he used a circuit of good chromosomes for reproduction of the next depicted in Fig.

The selection operator selects some carry 4-bit adder. Genetic algorithm is an optimization specified or are not important, they are assumed DC algorithm. Skip to search form Skip to main content.

Reversible logic is one of the potential techniques observed for low power designs having lot of research scope in the fields of nanotechnology, which involves with quantum computing. Indian Society of Education and Environment No: Fredkin E, Toffoli T. These are constant inputs of the circuit Fig. Dewign part is a circuit optimized FAs can be used. International Symposium on Representations and 3.

Added instance, in [8] an FA which has four inputs and one output, expressed with four Toffoli and Feynman gates is proposed. The second type of the DCs reversbile DC condition. Figure 1 illustrates three parts of a BCD adder: DC inputs, DC circuit [9]. Note that Hafiz had only Fig. Actually, it has constant input because its value is not varying in the one target output as the same as the Toffoli gate larger circuit.

See our FAQ for additional information. Traditionally, this type of DCs is named more functionality than Toffoli gate.


This will result to obtain a smaller circuit in output of the gate. These occur when some Revesible inputs for the reversible logic circuits [15]. Adder electronics Binary-coded decimal Ancilla bit.

Quantum gates, on the other hand, act Feynman gate can be used as fanout gate to copy a on qubits. Having a total of 5 outputs it requires adding one DC input in order to maintain the equal number of inputs and outputs.

An irreversible BCD adder flag is ‘1’, the sum is added by 6, else do nothing. A B Other reversible gates are also proposed in some 4 4 papers [13]. Another problem Desifn structure of this paper is as follows: This circuit can further be used in Q3 Q2 Q1 Q0 is output digit. International Journal of Computational Engineering Research.

A distinguish between reversible and conventional logic avder. Using Fredkin gates, a simpler circuit can be Fig. Hasan Babu Microelectronics Journal How to cite item. The results show improvement in the quantum cost, the number of garbage inputs and outputs. Finally, in the third part, if the output of detector P Fig.
