VHDL-AMS simulation for battery chargers News & Analysis 6/13/2001 Post a comment How easy-or-difficult is it to create VHDL-AMS models for analog circuits. Electronic Engineering in the UK published this Mentor Graphics code listing for a Maxim NiCd battery charged. Take a look...
Linux: the ideal client/server link News & Analysis 6/8/2001 Post a comment Some of the most innovative and revolutionary results occur when methods from one field are combined with methods from another. Networked file systems, digital signal processing and graphical user interfaces combined with Internet-enabled hypertext are just three of many examples. A new juxtaposition is emerging that could be just as profound in its effects--combining the traditional embedded paradigm with the classical network-based client/server model.
New Web services need structure News & Analysis 6/8/2001 Post a comment No one can dispute that the Web has fundamentally altered the way we shop, do business and are entertained. But underneath it all, the Web remains what it has always been-an enormous collection of networks that offers a pervasive and accessible medium for content and services.
Standards ease Web-app designs News & Analysis 6/8/2001 Post a comment Despite the market slump and the highly publicized failure of many dot-com ventures, the stampede to establish a business presence on the Web continues.
Solution to Web-service chaos: frameworks News & Analysis 6/8/2001 Post a comment As the World Wide Web morphs under our fingertips, companies, engineers and developers are trying to determine the exact nature of an environment that embraces high bandwidths, new types of devices, increased connectivity, new languages and protocols, and ways of using the Web that did not exist even a year ago.
