The Other Green
By Ed Sperling - 05 Aug, 2011 - Comments: 0

The human memory is rather short when it comes to certain things. Energy efficiency is one of them. While they may cringe at paying $4 a gallon for gasoline to fill of their car, they were convinced that drastic measures were necessary when gas hit $1 a gallon. And while consumers collectively account for the vast percentage of energy consumed, individually they don’t consume enough to mak... » read more

Who’s In Control?
By Ed Sperling - 26 May, 2011 - Comments: 0

By Ed Sperling A power shift is under way across the SoC world that ultimately determine who wins the business, who gets the biggest share and what technologies are ultimately used to get there. Complexity has reached a point where being able to pull the necessary pieces from a disaggregated supply chain is becoming much more difficult. That helps explain why all three of the major EDA comp... » read more

Engineering’s Growing Blacklist
By Ed Sperling - 25 Mar, 2011 - Comments: 0

The number of system-level design flaws is rising, and they’re not just little mistakes. These are high-profile errors that are making headlines all over the globe. While it’s debatable whether Toyota’s problem was a hardware or software design glitch, the simple fact is there was a design flaw somewhere. That’s true for the BP Gulf of Mexico leak, regardless of who’s responsible f... » read more

Software Drives Design Requirements
By Ed Sperling - 23 Sep, 2010 - Comments: 0

By Ann Steffora Mutschler As product design evolves to contain more and more software, that software—including the applications that run on the device—is now starting to drive design and process requirements. This change is causing ripples throughout the semiconductor industry, driving evolutionary thinking about where to go next. OEMs have taken notice of a new dynamic and want to capt... » read more

One On One With South Korea’s CTO

By Ed Sperling Chang-Gyu Hwang, national chief technology officer for South Korea, sat down with Low-Power Engineering to talk about the future trends in technology, global business and power. Prior to his current role, which was created by the Korean government in April, he ran the semiconductor business at Samsung, where he spent the last 20 years in top management positions. He also is the... » read more

Why Your iPhone Battery Doesn’t Last
By Jon McDonald - 22 Apr, 2010 - Comments: 0

By Jon McDonald The other day a friend asked about the battery life on my iPhone. I love the phone by the way; he was disappointed with how often he had to recharge his. I responded with the one thing I had tried—turn off the Bluetooth. With that one change I have been pretty happy with the time between charges. His question got me thinking about the battery life of the phone, and I start... » read more

The Long And Painful Path To Power Optimization
By Ed Sperling - 11 Mar, 2010 - Comments: 0

By Ed Sperling Think about any mobile Internet device today. Batteries typically last all day, applications shut down with ease, and the number of things it can do has reached the point where many people typically carry one device on the road rather than multiple devices they used to lug around several years ago. Perhaps even more astounding is the price drop on these devices. A basic cell ... » read more

Apple’s Re-aggregation Anomaly
By Ed Sperling - 28 Jan, 2010 - Comments: 0

Apple’s new iPad is an interesting device not so much because of what it offers to consumers—that’s certainly interesting in its own right—but because of how Apple built the device and why. Apple has been scouring the market for seasoned semiconductor engineers of late. The process started two years ago when the company hired a team of former engineers from the late Digital Equipme... » read more

The Next Big Thing, And Who Will Own It
By Ed Sperling - 24 Sep, 2009 - Comments: 0

At the beginning of this decade a writer for a powerful newspaper told me that, come hell or high water, she wasn’t giving up print—no matter how important online got to be. I had to think about that for awhile before answering, “It may not be your choice.” That newspaper is now a shadow of what it once was, but the statement keeps reminding me of some of the brash claims being mad... » read more

Following The WLAN Alphabet To Lower Power
By Ed Sperling - 20 Aug, 2009 - Comments: 0

By Cheryl Ajluni The quest for low power in electronic devices is one that shows no sign of abating any time soon. Pressure for it comes from many different sources, such as the continual drive to pack more functionality into ever smaller, mobile electronic devices. To try and maintain a decent battery life for today’s power-hungry “road-warriors,” engineers have to reduce power con... » read more
