Reversible logic has promising applications in the field of quantum computing, optical computing, low power computing, and other emerging computing technologies. A barrel shifter that can shift and rotate multiple bits in a single cycle is an important component of many computing units. This paper presents the reversible design of bidirectional arithmetic and logical barrel shifter. The proposed design...
In [1] we have presented the reversible subtractor designs based on a new reversible TR gate (TR refers to Thapliyal Ranganathan). In [1] as the quantum gates implementation of the TR gate was not known, only the upper bound on the quantum cost of the reversible subtractors units were established. In this work, we present a new design of the reversible half subtractor based on the quantum gates implementation...
The study of reversible circuits holds great promise for emerging technologies. Reversible circuits offer the possibility for great reductions in power consumption, and quantum computers will require logically reversible digital circuits. Many different reversible implementations of logical and arithmetic units have been proposed in the literature, but very few reversible floating-point designs exist...
This paper presents the novel designs of reversible sequential circuits (latches and flip flops). The proposed reversible latches and flip flops are designed from reversible Fredkin, Feynman and Toffoli Gates. Two new reversible gates called modified Fredkin gate (MFG) and Modified Toffoli Gate (MTG) are also proposed to design the optimized implementations. The proposed designs are better than the...
Reversible logic is emerging as a promising computing paradigm having its applications in low power VLSI design, quantum computing, nanotechnology and optical computing. In this paper, a new 4*4 reversible gate termed `OTG' (Online Testable Gate) is proposed suitable for online testability in reversible logic circuits. OTG can also work singly as a reversible full adder with a bare minimum of two...
Differential Power Analysis (DPA) presents a major challenge to mathematically-secure cryptographic protocols. Attackers can break the encryption by measuring the energy consumed in the working digital circuit. To prevent this type of attack, this paper proposes the use of reversible logic for designing the ALU of a cryptosystem. Ideally, reversible circuits dissipate zero energy. Thus, it would be...
The major time consuming arithmetic operations in ECC are point additions and doubling. Exponentiation operations like square and cube are the major bottlenecks in the efficiency of point additions and doubling. This paper presents efficient hardware circuitry for point doubling using square algorithms of Ancient Indian Vedic Mathematics. In order to calculate the square of a number, "Duplex"...
