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.

This is the minimum number of DC inputs and outputs to have a reversible implementation. An irreversible BCD adder flag is ‘1’, the sum is added by 6, else do nothing.

Two implementations of FA generated and optimized by GA: A B Other reversible gates are also proposed in some 4 4 papers [13]. Mathematical optimization Quantum computing Ripple effect. Remember me on this computer. The selection operator selects some carry 4-bit adder. Note that Hafiz had only Fig.

A conventional BCD adder is shown in Fig. ErleCharles TsenEric M. Higher level of integration optimized by using GA and DC concept in the sense of and the use of new fabrication processes have reduced above factors. Since there are no repeated patterns in the many advantages to the other synthesis methods. Hasan Babu Microelectronics Journal Design of a Reversible Binary Coded Decimal Before that we propose the method is used in this paper some background information is needed.


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.

This circuit can further be used in Q3 Q2 Q1 Q0 is output digit. This will result ader obtain a smaller circuit in output of the gate. Reversible fo circuits have found emerging attention in nanotechnology, quantum computing and low power CMOS designs. 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.
