Convolutional Neural Networks Power Ahead
By Ann Mutschler - 18 Apr, 2016 - Comments: 0

While the term may not be immediately recognizable, convolutional neural networks (CNNs) are already part of our daily lives—and they are expected to become even more significant in the near future. [getkc id="261" kc_name="Convolutional neural networks"] are a form of machine learning modeled on the way the brain's visual cortex distinguishes one object from another. That helps explain wh... » read more

Analyzing The Integrity Of Power
By Ann Mutschler - 14 Apr, 2016 - Comments: 0

Power analysis is shifting much earlier in the chip design process, with power emerging as the top design constraint at advanced process nodes. As engineering teams pack more functionality and content into bigger and more complex chips, they are having to deal with more complex interactions that affect everything from power to its impact on signal integrity and long-term reliability. That, i... » read more

Are Models Always The Answer?
By Ann Mutschler - 14 Apr, 2016 - Comments: 0

Given the shift to system level design and the need to make tradeoffs early in the design process, much emphasis is placed on modeling, and for good reason. Tobias Bjerregaard, CEO of Teklatech reminded that power integrity analysis and signal integrity analysis evolved to be more or less a checkmark from many companies. “They run it and then say, ‘OK, it is fine,’ but they don't think... » read more

System Bits: April 12

Highly aligned, wafer-scale films Rice University researchers, with support from Los Alamos National Laboratory, have created inch-wide, flexible, wafer-scale films of highly aligned and closely packed carbon nanotubes with the help of a simple filtration process. The chirality-enriched single-walled carbon nanotubes assemble themselves by the millions into long rows that are aligned better... » read more

Counterfeiting In The Automotive Supply Chain
By Ann Mutschler - 07 Apr, 2016 - Comments: 0

While counterfeiting is not a new problem in the automotive space by any means, the stakes are higher all the time when you consider the increase in more sophisticated electronics and electronic systems being designed into vehicles today. While we don’t want to think about the worst case scenario of a counterfeit airbag in the family minivan or a counterfeit battery in a hybrid vehicle, we mu... » read more

The Race To Secure The Car
By Ann Mutschler - 07 Apr, 2016 - Comments: 0

A shift is underway in the automotive industry to connect cars to each other and to a variety of communications infrastructure, adding many of the features that consumers now expect in mobile devices as well as some new ones that ultimately will lead to autonomous vehicles. But along with those changes are some nagging questions about just how safe that technology will be for consumers and othe... » read more

System Bits: April 5

Encoding electrons with valleytronics Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a new type of electronics that could lead to faster and more efficient computer logic systems and data storage chips in next-generation devices that they refer to as “valleytronics.” Specifically, the team has experimentally demonstra... » read more

What Cognitive Computing Means For Chip Design
By Ann Mutschler - 30 Mar, 2016 - Comments: 1

Cognitive computing. Artificial intelligence. Machine learning. All of these are concepts aim to make human types of problems computable, whether it be a self-driving car, a health care-providing robot, or a walking and talking assistant robot for the home or office. R&D teams around the world are working to create a whole new world of machines more intelligent than humans. Designing sys... » read more

System Bits: March 29

Cryptographic system for controlling app access to data Researchers at MIT and Harvard University are hoping to change the fact that users of smartphones have no idea which data items their apps are collecting, where they’re stored, and if they’re stored securely with an application they’ve developed called Sieve. With Sieve, a Web user would store all personal data, in encrypted form... » read more

Coherency, Cache And Configurability
By Ann Mutschler - 24 Mar, 2016 - Comments: 0

Coherency is gaining traction across a wide spectrum of applications as systems vendors begin leveraging heterogeneous computing to improve performance, minimize power, and simplify software development. Coherency is not a new concept, but making it easier to apply has always been a challenge. This is why it has largely been relegated to CPUs with identical processor cores. But the approach ... » read more
