Abstract—I design Coarse-Grained Reconfigurable Array (CGRA) architectures and build the CAD algorithms that map applications onto them, aiming for near-ASIC efficiency without giving up programmability.

Index Terms—CGRA architecture, reconfigurable computing, CAD algorithms, computer architecture, RTL design and verification, HLS.

Introduction

I am a PhD candidate at the University of Toronto, working with Prof. Jason Anderson. My research centers on Coarse-Grained Reconfigurable Arrays (CGRAs), a class of reconfigurable architectures that approach ASIC performance and energy efficiency while staying programmable at runtime. I design and explore CGRA architectures [1], [2], and build the CAD mapping algorithms that run applications on them [3]. I also completed a research internship at RIKEN Center for Computational Science with Dr. Kentaro Sano [2].

Before my PhD, I was a Silicon Design Engineer at AMD in India. As an undergraduate in Electronics, I interned with Prof. Paolo Ienne at EPFL on Dynamatic, with Prof. Kamakoti at IIT Madras on the Shakti processor, and took part in Google Summer of Code with BeagleBoard.org on BeagleWire. My undergraduate thesis accelerated deepfake detection on FPGAs [4].

I am open to collaborations in computer architecture, reconfigurable computing, and RTL design & verification. If you would like to collaborate, reach out to me at omkar.bhilare@mail.utoronto.ca.

Acknowledgment

I am grateful to my advisor, Prof. Jason Anderson, for guidance and support throughout my Ph.D. I thank Dr. Kentaro Sano and Dr. Tomohiro Ueno for hosting my research internship at the RIKEN Center for Computational Science in Kobe; Prof. Paolo Ienne and Mr. Andrea Guerrieri at the Processor Architecture Laboratory (LAP), EPFL, for mentoring my Summer@EPFL work on Dynamatic; Mrs. Lavanya J at the SHAKTI Lab, IIT Madras, for mentoring my verification internship; and Dhrubajyoti Sarma and K. Prabhu at AMD for their mentorship during my time as a silicon design engineer.

Above all, I thank my mom, my dad, and my two sisters for their love and constant support, and my friends for being there through every deadline.

Finally, thanks to the cricket pitch, the table-tennis table, the chessboard, a long reading list, and an unreasonable amount of coffee for keeping me sane along the way. Thanks also to the places I have been lucky enough to photograph.
