The multiplication operation is present in many parts of a digital system or digital computer, most notably in signal processing, graphics and scientific computation. With advances in technology, various techniques have been proposed to design multipliers, which offer high speed, low power consumption and lesser area. Thus making them suitable for various high speeds, low power compact VLSI imp...

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 ...

BACKGROUND Radix et Rhizoma Rhei has a gastric mucosal protective effect, major anti-gastritis and anti-peptic ulcer active constituents were emodin, aloe-emodin, chrysophanol, rhein, etc. The objective of the study was the extraction process of total anthraquinones in Radix et Rhizoma rhei and their antilipemic effects. MATERIALS AND METHODS Orthogonal experiment, UV spectrophotometry and co...

OBJECTIVE To evaluate the effect of Radix euphorbiae pekinensis extract on the permeability and bioavailability of paclitaxel co-administered orally. METHODS Based on Ussing Chamber and in vivo experiment, the permeability and bioavailability of paclitaxel were evaluated after oral co-administration with radix euphorbiae pekinensis in rats. The contents of paclitaxel in the permeates and the ...

We present the design of parallel architectures for the computation of the Hough transform based on application-specific CORDIC processors. The design of the circular CORDIC in rotation mode is simplified by the a priori knowledge of the angles participating in the transform and a high throughput is obtained through a pipelined design combined with the use of redundant arithmetic (carry save ad...

In this paper, we explore the potential of bus interconnection models using the Multiple-Valued Logic paradigm to reduce the power consumption of on-chip address and data buses within embedded SoC platforms. Data is sent over the buses using radix-r number system, i.e. ternary, balanced ternary or quaternary, rather than binary. This allows more compact bus design with less number of bus lines....

In a recently published paper “An Arithmetic Free Parallel Mixed-Radix Conversion Algorithm”, two algorithms based on look-up tables for mixed-radix conversion are presented. Here we show that one of the algorithms had been prior published in 1978, and we also take this opportunity to speak to the use of look-up tables for RNS with present and future technologies.

A new high-radix systolic multiplier architecture is presented for Montgomery modular multiplication. Using a radix 2, an n-bit modular multiplication only takes about n/w+6 cycles. This leads to a competitive ASIC implementation for RSA and Elliptic Curve Cryptography (ECC).
