SAFARI Live Seminar - From C/C++ code to high‐performance dataflow circuits

Title: From C/C++ code to high‐performance dataflow circuits Speaker: Lana Josipović, Assistant Professor in the Department of Information Technology and Electrical Engineering at ETH Zurich SAFARI Live Seminar Talk https://safari.ethz.ch/safari-live-seminar-lana-josipovic-nov-7-2022/ Slides (pdf): https://safari.ethz.ch/safari_public_wp/wp-content/uploads/Josipovic-HLS.pdf Abstract: High-level synthesis (HLS) tools generate digital hardware designs from high-level programming languages (e.g., C/C++) and promise to liberate designers from low-level hardware description details. Yet, HLS tools are still acceptable only for certain classes of applications and are criticized for the difficulty of extracting the desired level of performance: generating good circuits still requires tedious code restructuring and hardware design expertise. In this talk, I will present a new HLS methodology that produces dynamically scheduled, dataflow circuits out of C/C++ code; the resulting circuits achieve good performance out-of-the-box and realize behaviors that are beyond the capabilities of standard HLS tools. I will outline mathematical models to optimize the performance and area of the resulting circuits, as well as techniques to achieve characteristics that standard HLS cannot support, such as out-of-order memory accesses and speculative execution. These contributions redefine the HLS paradigm by introducing characteristics of modern superscalar processors to hardware designs; such behaviors are key for specialized computing to be successful in new contexts and broader application domains. Bio: Lana Josipović is an Assistant Professor in the Department of Information Technology and Electrical Engineering at ETH Zurich. Prior to joining ETH Zurich in January 2022, she received a Ph.D. degree in Computer Science from EPFL, Switzerland. Her research interests include reconfigurable computing and electronic design automation, with an emphasis on high-level synthesis techniques to generate hardware designs from high-level programming languages. She developed Dynamatic, an open-source high-level synthesis tool that produces dynamically scheduled circuits from C/C++ code. She is a recipient of the EDAA Outstanding Dissertation Award, Google Ph.D. Fellowship in Systems and Networking, Google Women Techmakers Scholarship, and Best Paper Award at FPGA'20.
