Item Open Access TRINE: a tree-based silicon photonic interposer network for energy-efficient 2.5D machine learning acceleration(Colorado State University. Libraries, 2023-10-28) Taheri, Ebadollah, author; Mahdian, Mohammad Amin, author; Pasricha, Sudeep, author; Nikdast, Mahdi, author; ACM, publisher2.5D chiplet systems have showcased low manufacturing costs and modular designs for machine learning (ML) acceleration. Nevertheless, communication challenges arise from chiplet interconnectivity and high-bandwidth demands among chiplets. To address these challenges, we present TRINE, a novel tree-based silicon photonic interposer network for energy-efficient ML acceleration. Leveraging silicon photonics and broadband optical switching, TRINE enables efficient inter-chiplet communication with reduced latency and improved energy efficiency. Considering several ML workloads, our simulation results demonstrate significant improvements in the average energy efficiency by 61.7% and 40% when comparing TRINE with two recently proposed silicon photonic interposer networks. By overcoming communication limitations in 2.5D ML accelerators, this work is a promising step towards advancing 2.5D photonic-based ML accelerator design.
