System Bits: Oct. 22
By Ann Mutschler - 22 Oct, 2013 - Comments: 0

Untangled nanotubes Carbon nanotubes are lightweight, strong and conduct electricity, which make them ideal components in new electronics devices, such as tablet computers and touchscreen phones, but cannot be used without being separated out from their natural tangled state. Researchers from Imperial College London have developed a way to unravel and apply carbon nanotubes in the laboratory a... » read more

Approaching IP Quality From Many Angles
By Ann Mutschler - 17 Oct, 2013 - Comments: 0

As SoC design complexity has increased, semiconductor design IP and the industry around it has grown in its level of sophistication. This is great news for the users of that IP whose demands for quality, reliability and other deliverables have also been on the rise. Making sure users have what they need requires close collaboration between the semiconductor foundries, IP providers and of cou... » read more

System Bits: Oct. 15

Improving safety with talking vehicles Researchers at USC Viterbi have spent nearly a decade working on algorithms and software to make it possible for cars to “talk” to one another by sending messages through an ad hoc wireless network to alert drivers of impending dangers such as potholes and icy roads to prevent accidents, injuries and the accompanying traffic jams. It’s all about hav... » read more

Power/Performance Bits: Oct. 15

Perfect ICs Are integrated circuits "too good" for current technological applications? Christian Enz, the new director of the Institute of Microengineering at Ecole Polytechnique Fédérale de Lausanne (EPFL) believes perfection is overrated. Enz said the reason why we should build our future devices with unreliable circuits, and adopt the "good enough engineering" trend is that non-fully r... » read more

Experts At The Table: How To Improve IP Quality
By Ann Mutschler - 11 Oct, 2013 - Comments: 0

Semiconductor Engineering sat down to discuss the best ways to improve the quality of design IP with Piyush Sancheti, vice president of product marketing at Atrenta; Chris Rowen, Cadence Fellow and former CTO at Tensilica; Gene Matter, senior applications manager at Docea Power; Warren Savage, president and CEO of IPextreme; and Dan Kochpatcharin, deputy director of IP portfolio marketing at TS... » read more

Don’t Stop Listening
By Ann Mutschler - 10 Oct, 2013 - Comments: 0

While it has been some years now, I admit I used to be a dedicated Blackberry user and could not understand the fascination with the iPhone initially. I knew exactly how my Blackberry worked, I loved the keyboard (or so I thought) and while a Macophile as well, I was reluctant to switch to a new smartphone, even though it was from my favorite PC maker. And then I had a chance to play with an... » read more

Transient Current Crunch
By Ann Mutschler - 10 Oct, 2013 - Comments: 0

When Intel talks, people listen. So when Intel executive VP Dadi Perlmutter said in a keynote at ISSCC in 2012 that transient power noise was one of the most limiting aspects of the chip design process—and how the package and the board inductance are limiting how low they can take the supply voltage—it showed the gravity of the challenge of effectively managing transient power. Transient po... » read more

On-Chip MCUs Excel At Power Management
By Ann Mutschler - 10 Oct, 2013 - Comments: 0

By Ann Steffora Mutschler When it comes to supplying power to an SoC, there is an increasing trend to make it more intelligent—how to control it more accurately, how it is monitored and how it communicates with different aspects of the chip. Traditional power supply models with analog supplies have less of this control, so a number of engineering teams are considering the use of on-chip m... » read more

Flexibility Improves Memory Interface Bandwidth
By Ann Mutschler - 10 Oct, 2013 - Comments: 0

In today’s SoCs, memory is the heart or at least one of the main elements of the design. As such, designing them carefully is paramount to achieving the best bandwidth, performance and power. Performance is very important to be able to access the memory and to trade and store information from different IPs with shared memories or local memories. From the power perspective, every access to... » read more

Power/Performance Bits: Oct. 8

How light interacts with gold nanostructures With the potential to possibly increase the efficiency of solar cells and photo detectors, University of Manchester researchers have discovered that graphene can be used to investigate how light interacts with nano-antennas. The team, which also included researchers from Freie Universität Berlin and Imperial College London, have shown that graph... » read more
