Signed Approach for Mining Web Content Outliers

Abstract

The emergence of the Internet has brewed the revolution of information storage and retrieval. As most of the data in the web is unstructured, and contains a mix of text, video, audio etc, there is a need to mine information to cater to the specific needs of the users without loss of important hidden information. Thus developing user friendly and automated tools for providing relevant information quickly becomes a major challenge in web mining research. Most of the existing web m ....etc

Abstract
Modular multiplication of long integers is an important
building block for cryptographic algorithms. Although
several FPGA accelerators have been proposed for large modular
multiplication, previous systems have been based on O(N2)
algorithms. In this paper, we present a Montgomery multiplier
that incorporates the more efficient Karatsuba algorithm which is
O(N(log 3= log 2)). This system is parameterizable to different bitwidths
and makes excellent use of both embedded multipliers and
fine-grained logic. The design has ....etc

Abstract:

Matrix multiplication is the kernel operation used in many image and signal processing applications. This paper demonstrates an effective design for the Matrix Multiplication using Systolic Architecture. This architecture increases the computing speed by using the concept of parallel processing and pipelining into a single concept. The selected platform is a FPGA (Field Programmable Gate Array) device since, in systolic computing, FPGAs can be used as dedicated computers in order to perform certain computations at very high frequenci ....etc

matrix multiplication in verilog code

Abstract

Digital multipliers are indispensable in the hardware implementation of many important functions such as DCT, IDCT, FFT etc in signal processing. This paper deals with Design and implementation of Vedic Multipler in Image Compression using DCT algorithm. The DCT (Discrete Cosine Transform) performs spatial compression of the data while IDCT performs decompression of the data. Here, matrix multiplication is one of the important step in both the transforms. Hence, to perform these computations, we ....etc

Fractions in the Canonical-Signed-Digit Number System


1 INTRODUCTION
In hardware DSP a signal can be scaled by a coefficient using
hardwired shifts and adds, but arithmetic operations are
fewer when subtractions are permitted also . The standard
approach uses coefficients in CSD, a radix-two number
system with ternary coefficient set f ....etc
