In this manuscript, an unusual adaptive FIR filter using distributed arithmetic (DA) for area efficient design is implemented. DA is bit-serial computational action and uses parallel look-up table (LUTs) apprise and equivalent implementation of filtering and weight-update operations to appliance high throughput filter rates irrespective of the filter length. The full adder based conditional sig...

In this paper, we propose a novel approach to perform efficient motion estimation specific to surveillance videos. A real-time background subtractor is used to detect the presence of any motion activity in the sequence. Two approaches for selective motion estimation, GOP-by-GOP and Frame-byFrame, are implemented. In the former, motion estimation is performed for the whole group of pictures (GOP...

Optical half subtractors are required for designing any optical computation system. Operation speed and the on/off contrast ratios very important characteristics logic device. A novel structure composed of three nonlinear ring resonators some waveguides used proposed subtractor with improved operation ratio. The simulation results show that rise time this is 1.5 ps. Also B D 13.7 dB 14.5 respec...

In this paper, we present a new non-restoring square root algorithm that is very efficient to implement. The new algorithm presented here has the following features unlike other square root algorithms. First, the focus of the “nonrestoring” is on the “partial remainder”, not on “each bit of the square root”, with each iteration. Second, it only requires one traditional adder/subtractor in each ...

We consider the design of synthetic embedded feedback circuits that can implement desired changes in the concentration of the output of a biomolecular process (reference tracking in control terminology). Such systems require the use of a “subtractor”, to generate an error signal that captures the difference between the current and desired value of the process output. Unfortunately, standard imp...
