Apple’s recent bout with ‘Batterygate’ highlighted just how important dynamic power management can be. Our last Sonics update looked at using their NoC to manage power islands; this time, we look at their research progress on architectural measures for power management.… Read More
For decades, tracing back to the days of Deming, the way to tackle complex engineering problems has been the pareto chart. Charting conditions and their contribution to the problem leads to mitigation priorities.
In the case of SoC power management, the old school pareto chart said the processor core was the biggest power hog and… Read More
ARM TechCon 2015 was another tour de force for ARM and its ecosystem. Besides some of the developments in mobile, IoT, and security (more coming soon in the Epilogue of “Mobile Unleashed”), there were two topics that I found very educational and will cover in blogs this week. One was how the Mali family is powering more than just mobile… Read More
Micrel Inc., one of the oldest chipmakers in Silicon Valley, has been acquired by Chandler, Arizona–based Microchip Technology Inc. for $839 million. A pure-play analog chip house will go to one of the leading microcontroller suppliers after regulatory approval amid the consolidation wave that has engulfed the semiconductor… Read More
As we celebrate the 50[SUP]th[/SUP] anniversary of the publication of Moore’s Law in Electronics Magazine (April 19, 1965), the industry finds itself in an increasingly costly global effort to keep transistor scaling on track. “Is Moore’s Law dead?” is a common question these days.
But practically speaking the doubling of transistor… Read More
Most of the buzz on network-on-chip is around simplifying and scaling interconnect, especially in multicore SoCs where AMBA buses and crossbars run into issues as more and more cores enter a design. Designers may want to explore how NoCs can help with a more power-aware approach.… Read More
I first met Dundar Dumlugolat Barcelona Design back in 2004, so it was a pleasure to meet with him again at DAClast week and learn more about what his company Magwel has to offer IC designers of power management chips.… Read More
In recent days I’ve seen several long discussions about Texas Instrumentslosing its grip in semiconductor industry when it came out of a business it was strong in, i.e. wireless business. It seems the semiconductor community has not digested the fact that TI, very rightly, came out of the OMAP business at the right time. The smartphone… Read More
How much power does a system consume? The simplistic path to power estimation for a system used to be tossing a few metrics – standby, typical, worst case, with figures pulled from a datasheet, simulation, or physical measurement – into a spreadsheet. After filling the remaining holes with SWAG (scientific wild-ass guesses), … Read More
My former co-worker, Kenneth Bakalar at Mentor Graphics is an expert in AMS modeling languages and UPFmethodology, so he recently teamed up with Eric Jeandeau to author an interesting white paper: Interpreting UPF for a Mixed-Signal Design Under Test. This white paper is based on a presentation made at DVCon earlier this year.… Read More
