This application note provides a detailed description of the Spartan™-3 configurationarchitecture. It Explains the composition of the bitstream file and how this bitstream isinterpreted by the configuration logic to program the part. Additionally, a methodology ispresented that will guide the user through the readback process. This information can be usedfor partial reconfiguration or partial readback.
This application note Explains the XC9500™/XL/XV Boundary Scan interface anddemonstrates the software available for programming and testing XC9500/XL/XV CPLDs. Anappendix summarizes the iMPACT software operations and provides an overview of theadditional operations supported by XC9500/XL/XV CPLDs for in-system programming.
Abstract: Many modern industrial, medical, and commercial applications require temperature measurements in the extended temperature rangewith accuracies of ±0.3°C or better, performed with reasonable cost and often with low power consumption. This article Explains how platinumresistance temperature detectors (PRTDs) can perform measurements over wide temperature ranges of -200°C to +850°C, with absolute accuracyand repeatability better than ±0.3°C, when used with modern processors capable of resolving nonlinear mathematical equation quickly and costeffectively. This article is the second installment of a series on PRTDs. For the first installment, please read application note 4875, "High-Accuracy Temperature Measurements Call for Platinum Resistance Temperature Detectors (PRTDs) and Precision Delta-Sigma ADCs."
Abstract: This application note Explains how to design an intelligent lighting controller that senses and measures the ambient lightlevel with an ambient light sensor (ALS). Equipped with a real-time clock (RTC), the controller also knows when to turn lighting on oroff at specified times. The system presented in this document can be used to control all luminaires that are mains-supply operated.Controller software is also provided in hex format.
Logger iButton devices have gained a lot of popularity with researchers. Although free evaluation software is easy to use and welldocumented, the choices and inputs that need to be made can sometimes be challenging. This application note Explains technicalterms that are common with temperature logger iButtons and how they relate to each other. Additionally, it presents an algorithm tohelp users choose the necessary input parameters, including the sample rate based on a user's needs and the available memory tostore the data.
Abstract: The reality of modern, small form-factor ceramic capacitors is a good reminder to always readthe data sheet. This tutorial Explains how ceramic capacitor type designations, such as X7R and Y5V,imply nothing about voltage coefficients. Engineers must check the data to know, really know, how aspecific capacitor will perform under voltage.
Libsvm is a simple, easy-to-use, and efficient software for SVM
classification and regression. It can solve C-SVM classification,
nu-SVM classification, one-class-SVM, epsilon-SVM regression, and
nu-SVM regression. It also provides an automatic model selection
tool for C-SVM classification. This document Explains the use of
libsvm.
With a worldwide community of users and more than a million dedicated programmers, Perl has proven to be the most effective language for the latest trends in computing and business.

OpenSG is a scenegraph system for realtime rendering, e.g. for Virtual Reality applications. It is just a library, not a full application.
This documentation contains descriptions of the internal classes and concepts, as well as a tutorial that Explains how to use the system.
This book presents an insightful view of XML that places this emerging technology in the context of the ongoing Web revolution. Written for business and technical professionals, this book revals the true value of XML for distributed information systems. It Explains how XML is transforming the way organizations manage data and build software systems details the opportunities the language offers for organizatoins that understand tis significance and potential impact and Explains how XML and Web services reflect a fundamental shift in software construction-from monolithic applications to software based on the composition of simple parts.
