Low Power Still Leads, But Energy Emerges As Future Focus
By Ann Mutschler - 10 Dec, 2020 - Comments: 1

In 2021 and beyond, chips used in smartphones, digital appliances, and nearly all major applications will need to go on a diet. As the amount of data being generated continues to swell, more processors are being added everywhere to sift through that data to determine what's useful, what isn't, and how to distribute it. All of that uses power, and not all of it is being done as efficiently as... » read more

Artificial Intelligence For Sustainable And Energy Efficient Buildings
By Fraunhofer IIS/EAS - 11 Nov, 2020 - Comments: 0

According to the goals of Europe’s green deal missions, the continent strives for becoming carbon neutral by 2050. Since buildings are a major contributor to the overall consumption of energy, improving their energy efficiency can be a key to a more sustainable and greener Europe. On the way towards zero-emission buildings, several challenges have to be met: In modern energy systems, several ... » read more

Saving Energy In The Fab
By Katherine Derbyshire - 09 Nov, 2016 - Comments: 7

It’s not an exaggeration to say that integrated circuits are a critical component of any effort to reduce global carbon dioxide emissions. The most efficient engines depend on microcontrollers to optimize fuel consumption. Global shipping uses sophisticated simulators for load balancing and route planning. Computing power that once needed room-sized cooling units now fits in a battery-powered... » read more

One-On-One: Dark Silicon
By Katherine Derbyshire - 09 Apr, 2015 - Comments: 0

Professor Michael Taylor’s research group at UC San Diego is studying ways to exploit dark silicon to optimize circuit designs for energy efficiency. He spoke with Semiconductor Engineering about the post-Dennard scaling regime, energy efficiency from integrated circuits all the way up to data centers, and how the manufacturing side can help. What follows are excerpts of that conversation. (F... » read more

How Long Will Your Battery Last?
By Ed Sperling - 12 Feb, 2015 - Comments: 0

Designing an IP block or memory subsystem to fit within a power budget is essential for building energy efficiency into hardware and software. There's only one catch—it's meaningless to the end customer. Twenty years ago this was a pretty straightforward formula. If you used a device consistently, whether it was a computer or a calculator or an electric motor, then you would burn up X numb... » read more

Making Software Better
By Ed Sperling - 07 Aug, 2014 - Comments: 0

Gauging the energy efficiency of software is a difficult task. There are many types of software, from embedded code all the way up to software that controls various modes of operation to downloaded applications. Some software interacts with other software, while other software works independently. And some works better on one SoC configuration than another, or on one iteration of an operating s... » read more

What’s Wrong With Power Signoff
By Ed Sperling - 12 Jun, 2014 - Comments: 0

Reducing power has emerged as the most pressing issue in the history of technology. On one hand, it’s the biggest opportunity the electronics industry has ever seen. On the other, the abuse of cheap power has been linked to global warming, human catastrophe, and geopolitical strife. In all cases, the semiconductor increasingly finds itself at the vortex of all of this, and making chips more e... » read more

The Denial Phase Is Over
By Ed Sperling - 10 Apr, 2014 - Comments: 0

For the last seven years—roughly since Apple first introduced the iPhone—the focus on power has become very real. In the past few years, that focus has shifted from power—how energy is used over time—to energy efficiency. This is more than just hair-splitting. It represents a fundamental and strategic shift for how SoCs and processors are architected, implemented and manufactured. ... » read more

Putting Energy In Perspective
By Ed Sperling - 22 Nov, 2013 - Comments: 0

The resurgent interest in 2.5D stacked die, the introduction of ultra-low-power memory and the relentless focus on low power for the Internet of Things are rather predictable progressions to engineers working in the semiconductor industry. What’s less obvious is how these changes are filtering out into the rest of the market and where it needs to go next. While many people have been talkin... » read more
