MULTISENSOR STRATEGIES TO SUPPORT BLIND PEOPLE: A CLEAR-PATH INDICATOR
Abstract :
The development of electronic sensing devices for the visually impaired requires knowledge of the needs and abilities of this class of people. In this project we present a rough analysis that can be used to properly define the criteria to be adopted for the design of such devices. In particular, attention will be focused on clear-path indicators, highlighting their role in orientation and mobility tasks. A new device belonging to this class i ....etc

HIGH-PERFORMANCE DSP CAPABILITY WITHIN AN OPTIMIZED LOW-COST FPGA ARCHITECTURE

ABSTRACT
The applications of Digital Signal Processing (DSP) continue to expand,
driven by trends such as the increased use of video and still images
and the demand for increasingly reconfigurable systems such as Software
Defined Radio (SDR). Many of these applications combine the need for
significant DSP processing with cost sensitivity, creating demand for
high-performance, low-cost DSP solutions.
General-purpose DSP chips ....etc

The best way to understand the requirements is to examine typical DSP algorithms and identify how their compositional requirements have influenced the architectures of DSP processor. Let us consider one of the most common processing tasks the finite impulse response filter.

For each tap of the filter a data sample is multiplied by a filter coefficient with result added to a running sum for all of the taps .Hence the main component of the FIR filter is dot product: multiply and add .These options are not unique to the FIR filter a ....etc

Introduction

This report presents three main topics we investigated as part of a project to build a Booth encoded multiply/accumulate VLSI chip. The original scope of work included synthesizing VHDL code using the Mentor Graphics tools. Exemplar was the VHDL compiler. Leonardo Spectrum was the synthesizer. Since my team, which included Kevin Delaney, did not meet a Mosis deadline our chip funding was lost. Since we did not actually fabricate a chip, we cannot discuss the success of our results. Likewise, VHDL synthesis using the ....etc

ROBUST AND EFFICIENT PASSWORD-AUTHENTICATED KEY AGREEMENT USING SMART CARDS FOR CAMPUS MANAGEMENT



(ABSTRACT)

The main objective of this project is to develop an embedded system, which is used for security for the campus management. In this security system the specific persons can only enter into the campus; by using this embedded system we can give access to the authorized people through the RFID tags and keypads.
The embedded system is going to be developed based on microcontroller; when ever the ....etc

Whereas analog filters are usually analysed in terms of transfer functions in the s plane using Laplace transforms, digital filters are analysed in the z plane in terms of Z-transforms. A digital filter may be described in the z plane by its characteristic collection of zeroes and poles.
Wavelet
An example of the 2D discrete wavelet transform that is used in JPEG2000. The original image is high-pass filtered, yielding the three large images, each describing local changes in brightness (details) in the original image. It is then low-pass fil ....etc

ABSTRACT
The Tiger SHARC processor is the newest and most power member of

this family which incorporates many mechanisms like SIMD, VLIW and

short vector memory access in a single processor. This is the first

time that all these have been combined in a real time processor.
The TigerSHARC DSP is an ultra high performance static superscalar

architecture that optimized for tele-communications infrastructure

and other computationally demanding applications.
The unique architecture combines elements o ....etc

Definition
Digital Signal Processing is carried out by mathematical operations. Digital Signal Processors are microprocessors specifically designed to handle Digital Signal Processing tasks. These devices have seen tremendous growth in the last decade, finding use in everything from cellular telephones to advanced scientific instruments. In fact, hardware engineers use DSP to mean Digital Signal Processor, just as algorithm developers use DSP to mean Digital Signal Processing. DSP has become a key component in many consumer, communications ....etc
