In this paper,we introduce an architecture of pre-encoded multiplier. The radix-4 modular multiplier can be used to implement fast computer applications, e.g RSA cryptosystem and to reduce the number of iterations and pipelining. The performance of these algorithms is primarily determined by the efficient implementation of the modular multiplication and exponentiation. Discussed a Booth's Radix...

The present work aims at proposing an efficient technique for signed binary multiplication using unsigned, multiply instruction. Numerous examples are provided to show efficiency of the proposed approach in the context of practical software implementation. Performance of the technique is compared to the software emulated versions of classical methods, such as radix-2 Booth method, reversal of s...

We present a unified mixed radix CORDIC algorithm with carry-save arithmetic with a constant scale factoi. The pipelined architecture of the processor is determined by a unique sequence of microrotations for the two modes of operation (rotation and vectoring) in circular and hyperbolic coordinates. The combination of radix-2 and radix-4 microrotations allows us to reduce the latency and size of...

In this paper we present alternate form of Radix-4/8 and split radix FFT’s based on DIF (decimation in frequency) version and discuss their implementation issues that further reduces the arithmetic complexity of power-of-two discrete Fourier Transform. This is achieved with circular shift operation on a subset of the output samples resulting from the decomposition in these FFT algorithms and a ...

A radix-16 fast Fourier transform (FFT) algorithm suitable for multiply-add instruction is proposed. The proposed radix-16 FFT algorithm requires fewer floating-point instructions than the conventional radix-16 FFT algorithm on processors that have a multiplyadd instruction. Moreover, this algorithm has the advantage of fewer loads and stores than either the radix-2, 4 and 8 FFT algorithms or t...

Classroom participation has been found to be directly related to education success (Jaasma, 1977). Given this, it is important to reduce communication apprehension in the classroom in order to increase participation. Early intervention is necessary because communication apprehension seems to have its strongest impact during the first two years of college (McCroskey, Booth-Butterfield & Payne, 1...

 The aim of this study was to investigate the pharmacokinetic profiles of baicalin, wogonoside, baicalein and wogonin after oral administration of pure baicalin, Radix scutellariae and Scutellariae-Paeoniae couple extracts were administered and the pharmacokinetics profiles were compared between normal and ulcerative colitis rats. The plasma concentrations of the four flavonoids were determined...
