Teaching Computers To See


Vision processing is emerging as a foundation technology for a number of high-growth applications, spurring a wave of intensive research to reduce power, improve performance, and push embedded vision into the mainstream to leverage economies of scale. What began as a relatively modest development effort has turned into an all-out race for a piece of this market, and for good reason. Mark... » read more

Partitioning For Power


Examine any smartphone design today and most of the electronic circuitry is "off" most of the time. And regardless of how many processor cores are available, it's rare to use more than a couple of those cores at any point in time. The emphasis is shifting, though, as the mobility market flattens and other markets such as driver-assisted vehicles and IoT begin gaining traction. In a car, turn... » read more

Energy Harvesting Gains Steam


Energy harvesting is gaining traction with a surge in ultra-low-power IoT applications, ranging from inventory tracking, wearables and drones, to vibration sensors for motors in industrial settings. The idea that machines could run without batteries—or that energy could be harvested either from motion or ambient sound waves or chemical reactions to augment battery power—has been in the w... » read more

Security Becomes A Multi-System Issue


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 Zen Of Processor Design


Mark Papermaster, chief technology officer at Advanced Micro Devices, sat down with Semiconductor Engineering to discuss how to keep improving performance per watt, new packaging options, and the increasing focus on customization for specific tasks. What follows are excerpts of that conversation. SE: As we get more into the IoT and we have to deal with more data, not to mention cars where da... » read more

The Real Value Of Digital Horsepower


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


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


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
