EDN Access -- 8.4.94 design features

Design Features: August 4, 1994

Cover Story

Synchronous Memories As system clock speeds push past 50 MHz, designers are discovering that asynchronous memory becomes unmanageable. As a result, they are looking to synchronous memories to handle increasing system speeds. What they are finding are new design challenges.

Design Features
The hottest new technologies and the latest design techniques to help you work efficiently and effectively.

Noise-figure curves ease the selection of low-noise op amps Evaluating plots of noise figure vs source resistance makes it easy to select a low-noise amplifier for a given source resistance. A BASIC program calculates the numbers from data-sheet parameters.
-- John W Christensen, National Semiconductor Corp

Canny choices condense CPLD and FPGA design cycles The proliferation of CPLDs and FPGAs has resulted in flexible devices that reduce design time and contribute to a design's smaller size, higher reliability, lower cost, and lower power consumption. However, you must choose from among many devices, each having its own diverse architecture.
--Sung C Hu, San Francisco State University

Embedded RISC µPs present new debugging challenges Embedded systems based on RISC mPs offer many advantages but present unique debugging challenges. Although a logic analyzer isn't the only tool you need to meet these challenges, it is an important one, and you should consider making it the cornerstone of your debugging strategy.
--Roger Crooks, Tektronix Inc

New philosophy aids shift from schematic-based Using HDL-based techniques for developing hardware is similar to using high-level languages to develop software: An object-oriented design philosophy is directly applicable.
--Charles F Shelor, Shelor Engineering

Software vendors sweep aside language barriers US software vendors face a dilemma: whether to thrust English-language products on foreign users or to "localize" products and offer their users native-language help, aide, ajuda, hjælp, hilfe, nápoveùda, ohje, pomoc, súgó, dowa, juseyeo...

Desktop DOS goes undercover to run embedded systems Embedding a PC often involves embedding the most popular desktop operating system.
