A high speed security algorithm is always important for wired/wireless environment. The symmetric block cipher plays a major role in the bulk data encryption. AES is one of the best existing symmetric security algorithms to provide data security. AES (Advanced Encryption Standard) is a specification published in 2001 by the American National Institute of(More)
In this manuscript, an adaptive FIR filter for high throughput, area and power efficient design will be introducing using distributed arithmetic (DA). DA is a bit serial computational action and uses equivalent concurrent realization of filtering weight update proposal for improving the throughput rate. As well as for high throughput rate and low area(More)
Many efficient algorithms and architectures for the design of low-complexity bit-parallel Multiple Constant Multiplications (MCM) operation that dominates the complexity of Digital Signal Processing (DSP) systems. On the other hand, digit-serial architectures offer alternative low-complexity designs, since digit-serial operators occupy less area and are(More)
— Orthogonal frequency division multiplexing (OFDM) is a popular method for wireless transmission of data at high rate. To increase the speed of transmission, the input high rate data stream is divided into many small data streams which are then transmitted parallel in OFDM system. The key component of OFDM system is the FFT processor. FFT converts the(More)
This paper presents a novel level set approach to simultaneous tissue segmentation and bias correction of Magnetic Resonance Imaging (MRI) images. We model the distribution of intensity belonging to each tissue as a Gaussian distribution with spatially varying mean and variance. We define a maximum objective function for each point in a transformed domain,(More)
The low power digital FIR Filter depending on digit serial adder and multiple constant multiplier (MCM) is explained in this paper. Digit serial architecture offers optimum area and does not dependent on word length. Paper developing a digit serial adder and MCM and presents the exact formalization of power optimization. Research work output indicate the(More)
