In recent years, deep learning has become widespread for various real-world recognition tasks. In addition to recognition accuracy, energy efficiency is another grand challenge to enable local intelligence in edge devices. In this paper, we investigate the adoption of monolithic 3D IC (M3D) technology for deep learning hardware design, using speech recognition as a test vehicle. M3D has recently proven...
In recent years, we have seen a surge of interest in neuromorphic computing and its hardware design for cognitive applications. In this work, we present new neuromorphic architecture, circuit, and device co-designs that enable spike-based classification for speech recognition task. The proposed neuromorphic speech recognition engine supports a sparsely connected deep spiking network with coarse granularity,...
Recent breakthroughs in deep neural networks have led to the proliferation of its use in image and speech applications. Conventional deep neural networks (DNNs) are fully-connected multi-layer networks with hundreds or thousands of neurons in each layer. Such a network requires a very large weight memory to store the connectivity between neurons. In this paper, we propose a hardware-centric methodology...
