Cryogenic CMOS Becomes Cool


Cryogenic CMOS is a technology on the cusp, promising higher performance and lower power with no change in fabrication technology. The question now is whether it becomes viable and mainstream. Technologies often appear to be just on the horizon, not quite making it, but never too far out of sight. That's usually because some issue plagues it, and the incentive is not big enough to solve the ... » read more

Near-Threshold Computing Gets A Boost


Near-threshold computing has long been used for power-sensitive devices, but some surprising, unrelated advances are making it much easier to deploy. While near-threshold logic has been an essential technique for applications with the lowest power consumption, it always has been difficult to use. That is changing, and while it is unlikely to become a mainstream technique, it is certainly bec... » read more

Telecare Challenges: Secure, Reliable, Lower Power


The adoption of telecare using a variety of connected digital devices is opening the door to much more rapid response to medical emergencies, as well as more consistent monitoring, but it also is adding new challenges involving connectivity, security, and power consumption. Telecare has been on the horizon for the better part of two decades, but it really began ramping with improvements in s... » read more

Power Domain Implementation Challenges Escalate


The number power domains is rising as chip architects build finer-grained control into chips and systems, adding significantly to the complexity of the overall design effort. Different power domains are an essential ingredient in partitioning of different functions. This approach allows different chips in a package, and different blocks in an SoC, to continue running with just enough power t... » read more

Can Analog Make A Comeback?


We live in an analog world dominated by digital processing, but that could change. Domain specificity, and the desire for greater levels of optimization, may provide analog compute with some significant advantages — and the possibility of a comeback. For the last four decades, the advantages of digital scaling and flexibility have pushed the dividing line between analog and digital closer ... » read more

Transforming AI Models For Accelerator Chips


AI is all about speeding up the movement and processing of data. Ali Cheraghi, solution architect at Flex Logix, talks about why floating point data needs to be converted into integer point data, how that impacts power and performance, and how different approaches in quantization play into this formula. » read more

More Options, Less Dark Silicon


Chipmakers are beginning to re-examine how much dark silicon should be used in a heterogenous system, where it works best, and what alternatives are available — a direct result of a slowdown in Moore's Law scaling and the increasing disaggregation of SoCs. The concept of dark silicon has been around for a couple decades, but it really began taking off with the introduction of the Internet ... » read more

Speeding Up AI Algorithms


AI at the edge is very different than AI in the cloud. Salvador Alvarez, solution architect director at Flex Logix, talks about why a specialized inferencing chip with built-in programmability is more efficient and scalable than a general-purpose processor, why high-performance models are essential for getting accurate real-time results, and how low power and ambient temperatures can affect the... » read more

Energy Harvesting Starting To Gain Traction


Tens of billions of IoT devices are powered by batteries today. Depending on the compute intensity and the battery chemistry, these devices can run steadily for short periods of time, or they can run occasionally for decades. But in some cases, they also can either harvest energy themselves, or tap into externally harvested energy, allowing them to work almost indefinitely. Energy harvesting... » read more

Power Now First-Order Concern In More Markets


Concerns about energy and power efficiency are becoming as important as performance in markets where traditionally there has been a significant gap, setting the stage for significant shifts in both chip architectures and in how those ICs are designed in the first place. This shift can be seen in a growing number of applications and vertical segments. It includes mobile devices, where batteri... » read more
