In multicore SOC architectures buses are a last resort
News & Analysis 9/29/2008 Post a comment
The one-processor system model that has dominated electronic system design since 1971 is now thoroughly obsolete. Today's SOC designers readily accept the idea of using multiple processors in their complex systems to achieve design goals and use the terms "control plane" and "data plane" to describe how these various on-chip processors are used on the chip. These terms appeared during the Internet and networking boom. At first, these terms referred to the design of multiple-board networking syst

Bluetooth headset turns to SUN and goes green
Teardown 9/29/2008 Post a comment
Last year, I purchased a hands-free Bluetooth car kit as a Christmas gift for a family member who, as a sales rep, spends significant time talking in her car. Worried for her safety as she drives with one hand on the wheel and the other around a cell phone, I initially felt a sense of pride as she unwrapped a gift that demonstrated concern for her well-being. Sometimes, however, a buzz can be short-lived. After a quick explanation of what the gift was, I could see a bit of uneasiness creep in as
Ultrasound imaging system design reshaped by AFEs
Design How-To 9/26/2008 Post a comment
Recent innovations are making it possible for new ultrasound systems to achieve much lower power and a significantly smaller footprint than ever before. Designing ultrasound systems is complex, and every feature of the analog front end (AFE) can influence system performance.
Control/monitoring solutions reduce energy costs in older plants
