In the era of edge AI, where computation meets real-world applications, the demand for high-performance, energy-efficient solutions has never been more pronounced. This seminar introduces an innovative approach to this challenge, introducing the fusion of cutting-edge neural network acceleration and Processing-In-Memory (PIM) technology in the design of advanced Edge AI chips. Traditional AI acceleration methods have paved the way, yet limitations in power consumption and data movement persist. Enter PIM, a revolutionary paradigm that unites processing and memory to redefine the landscape. This seminar delves into the intersection of PIM and neural networks, highlighting the pivotal role of in-memory computing in transforming Edge AI.Through comprehensive exploration, we delve into the intricacies of PIM-based neural network acceleration. We decipher the design considerations, from power-efficient hardware techniques to optimal memory hierarchies, and elucidate the synergistic possibilities when PIM converges with conventional AI accelerators. Real-world applications come to life, illustrating the prowess of PIM-powered neural networks across IoT, healthcare, autonomy, and beyond.
Dr. ChoongHyun Lee holds a Master’s degree and a Ph.D. in materials engineering from the University of Tokyo, Japan, achieved in 2010 and 2013 respectively. His academic pursuits were centered around advancing the frontiers of materials engineering, with a specific focus on interface control of Ge gate stack for high-performance logic applications.
