Counting ongate counts?Don’t count on it
Relying only on vendors’ data-sheet logic-count claims when selecting CPLDs or
FPGAs for your next design may result in unpleasant surprises down the road. Spend a
little extra time understanding the assumptions behind the numbers and the features of the
underlying device architectures to choose a chip that meets your needs.
-- Brian Dipert, Technical Editor
ADSL trims down with
G.lite 
Slow to satisfy its projected deployment numbers,
ADSL must now rely on the G.lite standard for consumer appeal. As computer and telephone
companies push G.lite, ADSL chip-set vendors are upgrading their products for
consumer-grade modems.

Kempainen, Technical Editor

Embedded operating-system
software—build or buy?
In spite of the industry’s push to commercial off the shelf and the shortened
time to market for new products, many embedded-system-development teams continue to write
their own real-time operating software. Before you decide to roll your own RTOS, take a
close look at your system requirements and develop a plan for the future.
-- Warren Webb, Technical Editor
EDN Hands-On Project:
Communication-simulation software smoothes system design
Modeling communication channel performance at the block-diagram level lets you walk
through your system architecture and algorithms before you run with specific
implementations.
-- Bill Schweber, Technical Editor
