Improved Efficiency


By Bhanu Kapoor We constantly hear about process technology advances and their impact on power consumption of ICs, but the power management techniques have remained the same over last few process technology generations. Power gating, dynamic voltage and frequency scaling, and threshold voltage scaling have been the key power management techniques since the 90nm process technology. Clock gating... » read more

A Balancing Act


By Ann Steffora Mutschler If you stay current on data center trends, you are well-versed on the fact that Intel reported last June energy proportionality has effectively doubled server efficiency and workload scaling beyond what Moore’s Law predicted. What does this have to do with power management of SoCs? Cary Chin, director of marketing for low-power solutions at Synopsys, said tha... » read more

Power Management: Throwing Down The Gauntlet


By Frank Ferro The recent burst of articles challenging smart phone battery life has me asking the question, “Are we ready to turn the corner on power consumption?” About two years ago I was bemoaning the fact that we are willing to live with a smart phone that gets only one day of battery life (Powering Forward or Moon Walking). As of today, nothing has changed. We still need to charge th... » read more

Good Times For Analog Designers


By Ann Steffora Mutschler For a number of technological reasons, analog/mixed-signal design and low-power design are converging, and with that comes both challenges and opportunities. As far as challenges go, process variations at 14nm, 20nm and even 28nm have increased significantly to include DFM impacts such as layout-delay effects. On the digital side, those process changes affect... » read more

Too Hot To Handle


By Ann Steffora Mutschler It used to be that a device could be designed to a thermal design power. The worst case power scenario would be imagined, and the device would be designed with that in mind. But those good old days are gone. Especially for consumer devices, how a device is going to behave with respect to time, or how people are going to use it, must be understood as completely a... » read more

Embedded Power Management Challenges Grow


By Ann Steffora Mutschler Power management always has been, and will continue to be, a big issue with electronic devices. But when it comes to power management in embedded systems—controlling battery power in a smartphone, an industrial automation or automotive application, among a myriad of other options—the approaches come with different variables. For example, deeply embedded s... » read more

All Things To All Customers


By Ann Steffora Mutschler Low-Power High-Performance Engineering recently spoke with Suresh Menon, VP of systems development at Lattice Semiconductor, about the challenges of directing the development of power-sensitive FPGAs from architectural decisions to identifying the target applications. What follows are excerpts of that discussion. LPHP: When you look at the products that Lattic... » read more

28, 20nm Nodes Demand Advanced Power Management


By Ann Steffora Mutschler With the complexity of getting 28 and 20nm designs to reach desired yields with the desired power and performance on the shoulders of design teams, advanced power management techniques are a must. Sub-clock power gating, clock power gate structures, adaptive body bias and other techniques are making it possible. Sub-Clock Power Gating Far from a new techniqu... » read more

Reducing Circuitry To Reduce Power


By Ann Steffora Mutschler Power is at the top of the list of concerns for design teams today. Consequently, engineers are constantly looking at new techniques and architectural approaches to lower and management the power and energy consumption of their devices. This has resulted in some incredible engineering feats, turning parts of a device on and off as needed, applying different volta... » read more

Training The Next Gen For Low Power


Reflecting on my time at this year's Design Automation Conference, I am quickly reminded that I work in the most fascinating industry I can think of. Having the opportunity to discuss deep technical low power design issues, forward-looking challenges as well as the business implications face to face with thought leaders is inspiring and invigorating. With the amount of brain power filling Mosco... » read more
