Energy-Efficient Deep Learning Accelerator: From Algorithm to Architecture



Deep learning algorithm has become the main stream for a wide range of machine learning applications, including computer vision (CV), natural language processing (NLP), and robotics. While deep learning algorithm outperforms many other state-of-the-art AI algorithms, the high computation and storage complexity pose a challenge to the extensive deployment in the energy-stringent embedded applications. In this talk, we will explore how algorithmic and architectural co-design can be used to design energy efficient hardware accelerator for the inference phase of the deep neural networks (DNN).  We propose SparseNN, a full-distributed architecture using Network-on-Chip (NoC) and exploiting the sparsity of the DNN to optimize the energy efficiency. In addition, we also address the issue of large memory footprints for the deep learning algorithm by compressing the weights of the neural network using a block hashing compressing technique.  The corresponding ASIC architecture for the block hashing neural network will also be presented. The design is implemented and demonstrated on an FPGA platform.  We will also discuss the use of an emerging memory device, Resistive RAM (RRAM), as an in-memory computing device for DNN architecture to address the memory wall issue.



Chi-Ying Tsui received his B.S. degree in Electrical Engineering from the University of Hong Kong and Ph.D. degree in Computer Engineering from the University of Southern California in 1994. He joined the Department of Electronic and Computer Engineering of Hong Kong University of Science and Technology in 1994 and is currently a full professor in the department and the Associate Dean of the School of Engineering.
