This paper proposes a hardware-efficient implementation of division, which is useful for image processing in WSN edge devices. For error-resilient applications such as processing, accurate calculations can be unnecessary overhead, and approximate computing that obtains circuit benefits from inaccurate effective. Since there are studies showing sufficient performance with few bit operations, thi...

An adder is a digital circuit that performs addition of numbers and it plays an important role in today’s digital world. In processors and other kinds of computing devices, Adders are used in the arithmetic logic units. They are also utilized in other parts of the processors for calculating addresses, table indices, increment and decrement operations and other similar operations because it is t...

We show all-optical switching of an input infrared laser beam at 1310 nm by controlling the photoinduced retinal isomerization to tune the resonances in a silica microsphere coated with three bacteriorhodopsin BR protein monolayers. The all-optical tunable resonant coupler re-routes the infrared beam between two tapered fibers in 50 s using a low power 200 W green 532 nm and blue 405 nm pump be...

At present, Boolean algebra based computations by the use of silicon based semiconductor technology are irreversible in nature. This is due to the mismatch of number of inputs and outputs. Reversible logic circuit maps unique input to the output and ensure one to one mapping and basis for emerging applications like low-power design, quantum computation, optical computing, bioinformatics and nan...

This paper describes a framework and tools for automating the production of designs that can be partially recon gured at run time. The approach involves several stages, including: (i) a partial evaluation stage, which produces con guration les for a given design, where the number of con gurations are minimised during the compile-time sequencing stage; (ii) an incremental con guration calculatio...

211 Abstract—-Different logic gates like MV, NOT, AOI, NNI etc under QCA nanotechnology are introduced. NNI gate is highly effective regarding space and speed consideration. Any Boolean functions, confined in thirteen number standard Boolean functions, are synthesized by MV and NNI gates or simply NNI gates alone, eliminating inverter (NOT) gate. A new method for realizing symmetric functions i...

Integrated Circuit(IC) fabrication technology is improving, so the internal dimension of semiconductor devices are decreasing day by day. This trend of scaling down dimensions reached its limit in near future. In nanoscale design, Complementary Metal Oxide Semiconductor (CMOS) has certain limitations such as hot electron effect, interconnect crosstalk, power dissipation, operating speed, gate o...

The demand of low power high speed circuits are in demand with the increasing universal growth in electronic system and the loss of information is not acceptable as with single loss of a bit information the energy loss is equal to kTlog2 joules/bit. Reversible logic can be of prominent interest to design low power arithmetic and data path units for digital signal processing applications, such a...
