Seminar title

Energy-Efficient Computing and Communication: Perspectives on Chiplet Interconnects and Photonic Networks

Speaker

Dr. Shenggao Li, Director, Mixed-Signal & RF Solutions Division, TSMC North America

Abstract

We are in the midst of a transformative computing revolution, driven by the explosive growth in AI and machine learning (ML) demands. Energy efficiency has emerged as a cornerstone in the design of high-performance supercomputers to meet the ever-growing requirements of daily training and inference workloads.

In this talk, we will delve into the evolution of chiplet interconnects and photonic interconnects, alongside advancements in process and packaging technologies. We will highlight how energy efficiency is fundamentally tied to innovations at every level—device, component, package, and system—enabling the next generation of energy-efficient, high-performance computing systems.
