Abstract—Reversible logic is the emerging topic for research due to its advantage of low energy consumption. Fault tolerant circuit design is required to give error free outputs. In this paper we present an optimized n bit Reversible Fault Tolerant Comparator design using parity preserving reversible logic gates. The Design involves MSB comparison as the first stage followed by Next Bit comparison stage which contributes for 1 bit garbage-less comparator design. The Design is generalized for n bit comparison. The performance parameters are analyzed for n bit. Our work outperforms the existing reversible fault tolerant comparator designs in terms of garbage output and Ancilla inputs or constant inputs. This efficiency of our design helps in*…show more content…*

Power dissipation is one of the most important criteria in VLSI design, optimizing the amount of power dissipated is the main requirement in low power VLSI design. Reversible logic has the ability to reduce the amount of power being dissipated and finds extensive use in numerous other technologies such as quantum computing [1], nanotechnology, optical information processing [2], low power CMOS design [3], DNA computing and bioinformatics. Reversible gates have a unique input-output mapping because of which bit loss can be recovered whereas in conventional logic, information is lost once the input is applied and cannot be recovered from its corresponding output. Whenever there is information loss KTln2 joules of energy is dissipated for every bit. This was asserted by R Landauer in 1960 [4], here T is absolute temperature and K is Boltzmann’s constant. Since there is no information loss in reversible logic, the amount of power dissipated is considerably less when compared to conventional logic. Hence, there is a high possibility of reducing power dissipation to minimal levels by implementing digital circuits using reversible logic gates. Synthesis of reversible circuits is different from conventional ones. Few conditions [1] have to be satisfied for the synthesis of reversible circuits. The conditions are as

2056 Words | 9 PagesAbstract- Power dissipation is one of the main issues in VLSI circuits. In recent years, Reversible logic gives a better solution for reducing power dissipation in system. Reversible logic has one-to-one mapping between input and output vectors. It has been used in various emerging applications like low power CMOS, Quantum computers etc. In the proposed work, the sequential circuits such as flip flop and shift registers are designed which enhanced performance by reducing area and power in terms of gate count, garbage outputs, and constant inputs.

## Le Chatelier's Theory

800 Words | 4 PagesThe converse is also true. If we add additional product to a system, the equilibrium will shift to the left, in order to produce more reactants. Or, if we remove reactants from the system, equilibrium will also be shifted to the left. Thus, according to Le Chatelier's principle, reversible reactions are self-correcting; when they are thrown out of balance by a change in concentration, temperature, or pressure, the system will naturally shift in such a way as to "re-balance" itself after the

## Theoretical Analysis Of Pipe Bend

813 Words | 4 PagesFor the flexibility factor, analytical solutions are presented in the case where a bend is approximated by a rigid restraint on both ends. To verify the analytical solution and its applicability limits, two numerical procedures are developed, which are based on the finite difference method and the reduction to the Kochi problem by the expansion of the unknowns in the Fourier series over the circumferential coordinate. The authors compared the results obtained with data from the literature, discussed the advantages and disadvantages of the methods, and presented recommendations for their practical application. Man Gyun Na el al. (2006) estimated the collapse moment due to wall thinned defects was estimated through fuzzy model identification.

2520 Words | 11 PagesWork of this type has been done by Job who developed the method of continuous variation [47]. This Method makes use of any measurable additive property of two species [48, 49]. Any complex formed by the two species must give a value for the separate species. The simple application of the method involves equilibrium of type: A + nB = ABn Where A represents a metal, B a coordinating group and ABn a complex. Solutions are prepared in which the mole fraction of the compounds are varied and the total number of moles of both, is kept constant.

## Advantages And Disadvantages Of Comparative Methods

846 Words | 4 PagesFor each of those comparative methods there are strengths, weaknesses and solutions for those weaknesses. The first method of comparison I will discuss is the method of comparing many countries. This method is also called ‘large-n’ comparison, where n stands for the number of countries. It’s very suitable with qualitative analysis of aggregate data. The presence of statistical control makes this method most like an experimental design, which has control groups and treatment groups (Landman & Carvalho, 2016).

## Relationship Between Thermodynamics And Economics

993 Words | 4 PagesWe learned in class that the thermal efficiency of the heat engine cannot be 100%, meaning all the heat that was input into the system will not be transformed into all work as some heat will be given off into a heat sink. As the Kelvin-Planck Statement says, it is impossible for any device that operates in a cycle to receive heat from a single reservoir and produce a net amount of work. Relating this to economics, there will be a limit to how much efficiency can increase in a production process, and inevitably there will have to be waste produced by the

Hence suitable multiplier structure will increase the performance and overall efficiency of the system. The Vedic multiplier improves the speed of the calculation and different types of reversible gates is use to reduce the power consumption because having ability of reversible computation that means no information loss take place. Reversible logic has wide application in the emerging technologies such as quantum computing, optical computing, Nano-technology etc.
