Luca Carloni: Accelerators and Coherence: An SoC Perspective

Virtual Computer Architecture Seminar

Event Details

Tuesday, September 22, 2020
4-5 p.m.

Abstract: The complexity of System-on-Chip (SoC) designs continues to grow as each SoC features an increasing variety of loosely coupled accelerators together with multiple processor cores. Specialized-hardware accelerators are typically designed in isolation, optimized for the algorithm they are implementing, and with limited consideration of the implications of their integration into a given SoC. However, the interaction between these accelerators and the memory hierarchy is critically important for their performance and the performance of the overall SoC. By leveraging our platform for rapid SoC prototyping, we analyze three models of coherence for loosely coupled accelerators from a system-level perspective.

Biography: Luca Carloni ( is Professor of Computer Science at Columbia University in the City of New York, where he leads the System-Level Design Group. He holds a Laurea Degree Summa cum Laude in Electronics Engineering from the University of Bologna, Italy, a Master of Science in Engineering from the University of California at Berkeley, and a Ph.D. in Electrical Engineering and Computer Sciences from the University of California at Berkeley.
