Security Becomes A Multi-System Issue
By Ed Sperling - 27 Oct, 2016 - Comments: 0

The fallout from the Mirai malware attack last week was surprising, given that it was published on the Internet several months ago as open-source. Despite numerous warnings, it still managed to cause denial of service attacks at Amazon, Netflix, and a slew of other companies that are supposed to be able to fend off these kinds of attacks. The good news is that it more people talking about th... » read more

The Real Value Of Digital Horsepower
By Ed Sperling - 08 Sep, 2016 - Comments: 0

Chipmakers and systems vendors are beginning to experiment with a slew of new ways to beef up performance and reduce power and area, now that shrinking features no longer guarantees those improvements. The number of new ideas introduced at industry conferences in the past few months is almost mind-boggling. Just on the CPU side there are new architectures that improve the amount of work that... » read more

Accuracy, Waveforms, And Power
By Ann Mutschler - 08 Sep, 2016 - Comments: 0

The entire topic of power analysis, estimation, and exploration never ceases to amaze me given that opinions on how to approach this are so varied. It is that diversity of opinions that makes it that much more intriguing. I’ve been particularly interested in how I now regularly hear that users are increasingly interested in taking activity from simulation and emulation and using that to dr... » read more

Power Options And Issues
By Ann Mutschler - 08 Sep, 2016 - Comments: 0

In the quest to get SoC power right as early as possible in the design flow, it still holds true that the biggest impact occurs at the beginning of the project, with diminished results as a design progresses through the flow toward tapeout. [getentity id="22186" e_name="ARM's"] big.LITTLE architecture has gained a lot of traction here, prompting MediaTek to introduce its Tri-Gear big.Medium.... » read more

Optimization Challenges For 10nm And 7nm
By Brian Bailey - 06 Sep, 2016 - Comments: 0

Optimization used to be a simple timing against area tradeoff but not anymore. As we go to each new node, the tradeoffs become more complicated involving additional aspects of the design that used to be dealt with in isolation. Semiconductor Engineering sat down to discuss these issues with Krishna Balachandran, director of product management for low-power products at [getentity id="22032" e... » read more

MediaTek Grabs Another Gear
By Barry Pangrle - 26 Aug, 2016 - Comments: 1

Today, it seems to be all the rage for automotive manufacturers to try to continuously one up the competition by announcing a new transmission that has more gears or “speeds." (Popular Mechanics did a nice article about why you would want more gears.) Basically, transmission designers want to keep the engine operating at or near its peak operating efficiency point and extend the operating ran... » read more
