Greetings!

Low-Power Design picked up the torch from Portable Design, which was all about energy efficient design. Looking at the macro-level implications we realized that "green engineering" is all about creating energy-efficient designs. The power management techniques first developed for portable devices apply equally well to their plugged-in brethren.
Low-power design is the key to a green future, and it's what Low-Power Design is all about. Our goal is to be the Engineer's Portal to Green Design. Our readers are engineering the future, and we're here to help.

Low-Power Design = Green Design
The New York Times earlier this week carried a story on how energy consumption by data centers is becoming a major and measurable problem worldwide: "In the United States alone, those data centers accounted for 1.5 percent of the country's electricity use in 2006 - more than the entire state of Massachusetts. And their power use could nearly double over five years, according to government reports."

Protectionism vs. the Innovation NationVivek Wadhwa reminded me of this this morning when I read his post Protectionism vs. the Innovation Nation. Those of us clinging to distant memories recall the near panic of the 1980s semiconductor business in which the Japanese, whom we graciously picked up in the aftermath of World War II, were about to deliver the coup de gras by taking over the chip industry entirely.

What do Superman, ASIC and SOC Design, and Newport Beach have in common?
What's the one thing you will do from now to the end of the year that will put you or your [ASIC or SoC] team ahead of the rampant, cutthroat global competition it will face in 2010? Do you even know? Let me give you the typical answer, the answer that I know I'd get from most of the engineers, designers, managers, and executives in this industry. It's a one-word answer. I know it because I've heard this answer over and over again. That answer is... nothing. More...

Next-Generation Design Issues in Communications
|
Next-generation communication systems are presented with many design challenges. We are moving into an age where the rules for spectrum access may change faster than new equipment can be fielded and faster than new software for the equipment can be developed. At the same time, heterogeneity is increasing. The rate of development of new technologies and new air interface standards (AISs) is continuing to grow. Research is now exploring many new modes for finding spectrum, for negotiating for use of spectrum, for adapting the modulation to fit into available spaces, and for protocols by which radios can exchange their capabilities in this new field of Cognitive Radio and Dynamic Spectrum.

Characterizing and Troubleshooting Digital RF Amplifier Systems
|
With the emergence of high-speed data services on the wireless mobile networks, new challenges have been placed on the design and operation of power amplifiers. The bursted nature of new wireless access technologies (3GPP - HSPA, LTE, WiMax, and 3GPP2 - 1xEV-DO) can wreak havoc on the modern amplifier design that previously had been designed for voice-only communication.

Ultra-Low Power Requires MCMM
|
ICs for smart phones, music players, and other portable products now depend on a palette of relatively exotic design methods, including multiple voltage domains, and dynamic voltage and frequency scaling (DVFS), to effectively manage power. These new techniques present a minefield of challenges to the entire design flow. More...

Architectural Issues for Power Gating
|
The global energy and climate crises that have gained significant awareness over the past six to eight years have "fueled" the emergence of so-called "green" technology initiatives in several key markets, most notably the information technology sector. Semiconductor component power consumption represents problematic challenges that include: mega-server farms consuming hundreds of megawatts, handheld consumer devices, and physical device scaling below 45nm semiconductor process nodes. The result has been a newfound awareness that "off-by-default" may become the mantra for next-generation semiconductor design practice. More... |
Good Embedded Communications is the Key to Multicore Hardware Design Success
|
While multicore processors have certainly become an important part of many SoC designs, there are still several obstacles designers face in dealing with more than one processing engine on a chip. Software engineers face the problem of trying to efficiently program multiple processor cores on the same piece of silicon. On the hardware side, chip developers - from architects down to physical implementation engineers - face difficult communication issues between the various processing and other IP cores and in accessing off-chip DRAM.

The Role of Digital Power in Portable Applications
|
Power management is vital to extending runtime for portable applications. Power conversion in these applications has been dominated by analog circuits, while the power management has been performed by embedded processors and simple sequencers. These analog solutions have served the system well. With recent trends in power solutions focusing on digital control, new opportunities emerge for portable power solutions. More...
