Abstract:

In the emerging artificial intelligence era, deep neural networks (DNNs), a.k.a. deep learning, have gained unprecedented success in various applications. However, DNNs are usually storage intensive, computation intensive and very energy consuming, thereby posing severe challenges on the future wide deployment in many application scenarios, especially for the resource-constraint low-power IoT application and embedded systems.In this talk, I will introduce my recent algorithm/hardware co-design works for energy-efficient DNN (MICRO'17,MICRO'18, ISCA'19).  First, I will show the use of low displacement rank (LDR) matrices can enable the construction of low-complexity DNN models as well as the corresponding energy-efficient DNN hardware accelerators. In the second part of my talk, I will show the benefit of using permuted diagonal matrix, as another type of structured and sparse matrix, for the energy-efficient DNN hardware design. Finally, I will introduce the benefits of tensor decomposition for DNN design and the corresponding high-performance DNN accelerator.
