Energy Vs. Power
By Ed Sperling - 06 Oct, 2011 - Comments: 0

By Ann Steffora Mutschler The terms power and energy are used almost interchangeably these days, but understanding and clearly articulating how to optimize embedded designs for maximum energy and power efficiency can make a big difference in a design. At a physics level, energy = power x time, whereas power is the rate of energy in a given time window. When the focus is specifically power, ... » read more

A Different Kind Of Design
By Ed Sperling - 16 Sep, 2011 - Comments: 0

Intel’s announcements at the Intel Developer Forum this week that it will be creating physically smaller packages that can run on far less energy raises some interesting questions about the future of all design. We’ve become accustomed to one-chip implementations, whether that’s a monolithic processor or an SoC with lots of processors. In the future, though, there may be multiple chips, a... » read more

The Big Picture
By Ed Sperling - 22 Jul, 2011 - Comments: 0

Business is booming for the makers of processors. Intel posted its five consecutive record quarter, AMD turned a profit, Tensilica shipped its billionth DSP, ARM and MIPS are both reporting strong earnings. So what’s changed? There are several distinct trends driving this upbeat mood: The replacement cycle. After years of putting off purchases through a prolonged and deep downturn, com... » read more

5 Ways To Cut Power
By Ed Sperling - 16 Jun, 2011 - Comments: 0

By Ed Sperling Low energy consumption with minimal leakage has emerged as the most competitive element in an IC design, regardless of whether it involves a plug, a battery, or whether it’s powered by a gasoline engine. While components on an SoC aren’t always power-aware, they’ll have to be in the future as consumers focus first on energy efficiency. With rising fuel costs, a concern ... » read more

The Impact Of Triple Play
By Ed Sperling - 12 May, 2011 - Comments: 0

By Ann Steffora Mutschler Not so long ago there were multiple networks that supported different kinds of traffic—a telecommunications network based on high-reliability protocols, the Internet for burst-centric data traffic and video distribution networks. From the consumer standpoint that was highly inefficient. Managing three subscriptions from three service providers was unnecessary, w... » read more

Talk, Talk And More Talk

By Ed Sperling To anyone who owns a cell phone—and there are at least several billion people who claim that distinction these days—it’s not surprising that bad reception lowers battery life. More bars, while not the most accurate gauge of a signal, are at least an indication that you can extend the time between charges even if you’re watching streaming video. But work is under way a... » read more

Mobile Applications Drive New Architectures
By Ed Sperling - 28 Apr, 2011 - Comments: 0

By Pallab Chatterjee The push toward mobility in consumer devices is having an impact on the entire component flow. Mobile devices are dominated by two key factors—an overriding power constraint and very high data bandwidth. The power constraints are on the mobile device side and on the cloud-based support server side. The high data bandwidth issues are due to the limited processing powe... » read more

Rationalization For Power
By Ed Sperling - 14 Apr, 2011 - Comments: 0

By Ed Sperling Power budgets are becoming almost universally problematic. What used to be a unique headache for the cell-phone market has evolved into an ugly migraine that now includes everything with a battery—and increasingly even those devices that rely on a plug. The result is a cascade of effects that are widespread and growing. And while the drivers of this effort vary widely from ... » read more
