[Technology Report]
Soft Peripherals + Hard Cores = Reconfigurable SoCs
Designers can incorporate an array of peripherals into asics and platform systems-on-a-chip. but custom designs have very high upfront costs, making them practical only when chip production runs are counted in the millions. Reconfigurable SoCs,... — William Wong

[Product Innovation]
Comm Processor Offloads Host, Delivers Gigabit Data Streams
As data transfer rates increase and system integrators strive to bring more services and features to the communications systems they're crafting, current-generation communications processors are running out of steam. Future enterprise routers, media... — Dave Bursky

[Design Application]
Design In Probing On High-Speed Buses To Improve Debugging
Just a couple of years ago, many designers struggled with bus and I/O speeds that continued to plod along while processors doubled their clock speeds every 12 to 18 months. Then, almost overnight, bus and I/O technology began to change. The speeds... — Gregg Buzard

[Ideas For Design]
PC And Long-Baseline Chronography Measure Ballistic Parameters Acoustically
Ballistics is an ancient art—one that was already old when longbows, catapults, and bronze smoothbore cannons were the high-tech missile projectors of their respective day. "External" ballistics undertakes the prediction of the trajectory of the... — W. Stephen Woodward

[Ideas For Design]
Measurement Circuit Features High Common-Mode Rejection
Modern measurement systems often operate with single 5-V power supplies, yet their input signals may have large common-mode voltages that exceed the supply by tens or hundreds of volts. Also, unless the converter is driven differentially, the noise on... — Moshe Gerstenhaber , et al.

[Ideas For Design]
Simple Technique Generates Precise HART Waveforms
Designed to complement conventional 4- to 20-mA analog signaling, the Highway Addressable Remote Transducer (HART) protocol supports two-way digital communications for process measurement and control devices. The protocol uses frequency-shift keying... — Anthony H. Smith

[Editorial]
Some Markets Have Hit Saturation, But Room For Growth Remains
As the volume of PCs produced almost levels off and the number of cell phones manufactured has dropped considerably, it might seem that the industry has begun a cycle of consumer saturation. Of course, a slowing in the economy also influences the... — Dave Bursky

[Pease Porridge]
Bob's Mailbox
Hello Mr. Pease: Thanks for writing all of these interesting tidbits of information over the years. I am tempted to purchase an old VW and wire up the sound system with some of that newfangled oxygen-free copper at $6/ft so that it... — Bob Pease

[Viewpoint]
Configurable DSP Processors Are Key To New Portable Devices
Anyone who uses a cell phone, digital camera, or television set-top box can see why the semiconductor industry is under pressure to find new solutions for today's design problems. Today's consumer devices demand new levels of flexibility from... — Victor Berman

[Editor's Notebook]
OLEDs Need Niche To Notch Victory Against LCDs
A panel session at the recent Society for Information Displays (SID) conference in Boston posed the question "OLEDs Versus AMLCDs: Do OLEDs Have A Chance?" That simple question sparked a spirited debate between industry experts representing active... — David G. Morrison

[Celebrating 50 Years]
Flashback
Flashback > 10 Years Ago JULY 23, 1992 Let me explain why i believe software is the future. After nine years at Sun, I learned that there is no such thing as a pure hardware business. There never... — Staff
