題目(Title) Hardware/Software Co-Design of Deep Learning Accelerators
概要(Abstract) The prevalence of deep neural networks today is supported by a variety of powerful hardware platforms including GPUs, FPGAs, and ASICs. A fundamental question lies in almost every implementation of deep neural networks: given a specific task, what is the optimal neural architecture and the tailor-made hardware in terms of accuracy and efficiency? Earlier approaches attempted to address this question through hardware-aware neural architecture search (NAS), where features of a fixed hardware design are taken into consideration when designing neural architectures. However, we believe that the best practice is through the simultaneous design of the neural architecture and the hardware to identify the best pairs that maximize both test accuracy and hardware efficiency. In this talk, we will present novel co-exploration frameworks for neural architecture and various hardware platforms including FPGA, NoC, ASIC and Computing-in-Memory, all of which are the first in the literature. We will demonstrate that our co-exploration concept greatly opens up the design freedom and pushes forward the Pareto frontier between hardware efficiency and test accuracy for better design tradeoffs.
