PC/104: an aging beauty By Warren Webb, Technical Editor
Even though Intel and Microsoft have jointly banned the bus from future desktop computers, ISA-based PC/104 embedded products show steady growth.
Issues in implementing queuing and scheduling for high-performance routers
Praveen Kumar, Vitesse Semiconductor Corp
Implementing traffic-management mechanisms and enforcing QoS guarantees in routers present significant challenges in scaling to next-generation routers and beyond. The best approach involves a mix of techniques, Including new algorithms to speed selected tasks, innovative hardware, and parallel-processing techniques.
Proper layout and component selection control power-supply EMI
Matt Schindler, Maxim Integrated Products
All power-supply components, including voltage regulators, inductors, and transformers, and their layout determine the amount of EMI a supply generates. An overview covers the mechanisms and physical principles governing the generation and propagation of power-supply electrical noise.
Designing high-current, VRM-compliant CPU power supplies Angel Gentchev, PhD, Analog Devices
The practical design of embedded, high-current, VRM9.0-compliant power supplies requires expertise in many disciplines of engineering and a thorough, methodical design procedure.
Image stabilization shows diversity of engineering approaches
By Bill Schweber, Executive Editor
To keep a camcorder or binocular image from bouncing, designers can call upon some sophisticated and clever techniques, each with its own set of features and trade-offs.
Display technology's results are compelling, but legacy is un"clear"
By Brian Dipert, Technical Editor
Microsoft and others are exploiting LCD subpixel characteristics in an attempt to economically improve the display quality of typefaces and other fine-detail images. Here's the theory behind the implementation and the reality behind the hype, along with a dose of controversy.
Tech Trends
Switching the light fantastic By Joshua Israelsohn, Technical Editor
As fiber carrying capacities move into multiterabit rates, equipment at the metropolitan-service/long-haul interface must cope with growing channel counts, not just channel speeds. Stretched between optical-electrical-optical solutions and the yet unrealizable all fiber network lie a number of devices that can, some say, push electrophotonic transduction to the enterprise interface and perhaps to your door.
