Advanced Materials: Mapping A Path To Low-Power Devices
By Cheryl Ajluni - 15 Mar, 2009 - Comments: 1

By Cheryl Ajluni For many electronics devices, especially those utilized in mobile applications, achieving low power is the Holy Grail. Unfortunately this goal is one that is not easily attained. In accordance with Moore’s Law, transistor density is continuing to increase. With each scaling, transistors are being designed smaller and faster to realize increased chip performance. But the risi... » read more

Minimizing Power Consumption In Next-Generation Mobile Devices
By Cheryl Ajluni - 13 Mar, 2009 - Comments: 0

By Cheryl Ajluni Today’s consumers continually demand ever more efficient and reliable means of mobile communication. At the same time, the wireless industry is evolving toward higher data rates and capacities. Both of these trends present a wealth of opportunity for innovative system engineers looking to design the next generation of mobile communication devices. They also pose some inter... » read more

On, Off and Mostly Off
By Ed Sperling - 13 Mar, 2009 - Comments: 0

<p>By Ed Sperling</p> <p>System-on-chip architecture has always been about getting the most performance out of a device, and the basic premise is that when you turn on a device it is always on.</p> <p>That approach has been challenged over the past few years with a fundamental shift toward more of the design being in the ‘off’ position. Aside from reversi... » read more

Writing Application Software Directly To The Metal
By Ed Sperling - 13 Mar, 2009 - Comments: 0

By Ed Sperling How necessary is an operating system? That question would have been considered superfluous a decade ago, possibly even blasphemous and career-limiting. But it now is beginning to surface in low-power discussions, particularly in compute-intensive applications where performance and power are both critical. General-purpose operating systems constantly call on the processor fo... » read more

Verifying Low-Power IP And Designs
By Ed Sperling - 13 Mar, 2009 - Comments: 0

By Ed Sperling Verification has always been the time-consuming part of designs. Even at 120nm and above, where power wasn’t much of an issue, verification accounted for an estimated 70 percent of the non-recurring engineering expense in a chip. Since then, the tools to automate design have become more effective, but the complexity of designs has grown by leaps and bounds beyond those tools.... » read more

Low-Power Standards War
By Ann Mutschler - 13 Mar, 2009 - Comments: 0

To the uninitiated, establishing a technology standard may seem straightforward. In reality, the process is mired with technical and political issues as evidenced by the ongoing battle for a de facto low-power design standard between the Unified Power Format (UPF) and the Common Power Format (CPF).   Currently, UPF is with the IEEE for final ratification as P1801, set for vote this month, ... » read more

Plumbing 101: Current Leakage And What to Do About It
By Brian Fuller - 13 Mar, 2009 - Comments: 0

By Brian Fuller Rising demand for mobile products and the march of Moore’s Law have created conditions for a perfect storm that threatens to swamp electronics designs and the market growth those designs target. The catalyst for that storm is leakage, which worsens the smaller devices become. Even in an “off” state, systems can leak like poorly insulated houses. But as the nation think... » read more

NoC Your SoCs Off
By Ed Sperling - 19 Feb, 2009 - Comments: 0

By Ed Sperling The network on a chip (NoC) approach is gaining ground as an essential part of a system on a chip (SoC), providing the same kind of time-to-market advantage that well-tested intellectual property blocks provide. This follows almost eight years of hype about NoCs potential with little to show for it. Times have changed and there appear to be two main drivers, one technological a... » read more

Beyond CMOS: Making Way For The Next-Generation Of Semiconductor Materials
By Cheryl Ajluni - 19 Feb, 2009 - Comments: 0

By Cheryl Ajluni Before the advent of the cell phone, the idea of having access to a phone virtually anytime, anywhere and in a package smaller than a human hand seemed almost impossible. Today that innovation, and others like it, has become an everyday reality. In the process it has helped spawn a technologically-driven society that continually demands more for less and waits impatiently... » read more

The Quest For Faster Data Throughput On A Chip
By Ed Sperling - 19 Feb, 2009 - Comments: 0

By Ed Sperling As with all network topologies, the general rule is the faster the better. Jack Browne, VP of sales and marketing at Sonics, said his customers are asking for higher-speed interconnects. “Right now we’re at 300MHz,” he said. “They want to more than double that in the very near future and eventually get to 1GHz.” Getting to that speed is no simple ... » read more
