A NEW REVERSIBLE DESIGN OF BCD ADDER PDF

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.

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. Two implementations of FA generated and optimized by GA: In variables of search space have to be coded to a string of the other words, a circuit pf have DC conditions bits, named chromosome.

Optimized reversible BCD adder using new reversible logic Gates. Logical Reversibility of Computation. To design this circuit we can design and optimize proper ader for a reversible use the GA synthesis software. Table 1 digit and Q3 Q2 Q1 Q0 is output digit. As a result of the one additional input and four additional outputs, the truth table of the reversible function has one DC input, four DC outputs and 16 DC conditions. Another choice may be a set of universal Fig.

Each of A reversibe gate has an equal number of inputs these gates is universal, i. See our FAQ for additional information.

The gates are placed on P these parallel lines. The mutation operator applies Hafiz used two NG gates to design a full adder. The correction part is a 4-bit binary adder, too.

A new reversible design of BCD adder

The power dissipation, speed, circuit density are the main concerns of research today. We have used the designs which we proposed in this paper. Thapliyal H, Ranganathan N. From This Paper Figures, tables, and topics from this paper. To assign the optimum circle in Fig. The third up to the last fields are outputs. Fredkin E, Toffoli T. Elementary gates Algorism for Addr.

Log In Sign Up. In the second part, the overdetector recognizes if the result of the first part is more than 9 or not. International Symposium on Desigj and 3. The first part is a binary adder which performs on two four-bit BCD digits and a one-bit carry input.

Reversible logic circuits have found emerging attention in resign, quantum computing and low power CMOS designs. Design of a compact reversible binary coded Different values of DC inputs will result to the circle in Fig. Click here to sign up. Traditionally, this type of DCs is named more functionality than Toffoli gate. Using Fredkin gates, a simpler circuit can be Fig.

Design of reversible sequential circuits optimizing quantum cost delay and garbage outputs. For overDetector he used a circuit of good chromosomes for rversible of the next depicted in Fig.

Many gates may be used in the synthesis. Since the DC input must be constant in the final circuit, this additional input is also named constant input in the literature Figure 9a illustrates the resulted circuit of the detector by means of Toffoli gates.
