Deep neural networks are gaining in popularity as they are used to generate state-of-the-art results for a variety of computer vision and machine learning applications. At the same time, these networks have grown in depth and complexity in order to solve harder problems. Given the limitations in power budgets dedicated to these networks, the importance of low-power, low-memory solutions has been stressed...
While Deep Neural Networks (DNNs) push the state-of-the-art in many machine learning applications, they often require millions of expensive floating-point operations for each input classification. This computation overhead limits the applicability of DNNs to low-power, embedded platforms and incurs high cost in data centers. This motivates recent interests in designing low-power, low-latency DNNs...
We present a novel dynamic configuration technique for deep neural networks that permits step-wise energy-accuracy tradeoffs during runtime. Our configuration technique adjusts the number of channels in the network dynamically depending on response time, power, and accuracy targets. To enable this dynamic configuration technique, we co-design a new training algorithm, where the network is incrementally...
In this work, a low-power, low-error divider design is proposed that can achieve significant power and area savings, while introducing insignificant inaccuracies to the output. The design of our divider is highly scalable, offering a wide range of power and inaccuracy trade-offs based on the application requirements. Furthermore, the proposed divider has a lower delay compared to the accurate design,...
Many applications for signal processing, computer vision and machine learning show an inherent tolerance to some computational error. This error resilience can be exploited to trade off accuracy for savings in power consumption and design area. Since multiplication is an essential arithmetic operation for these applications, in this paper we focus specifically on this operation and propose a novel...
