Exploration of cache coherence for CPU-FPGA heterogeneous systemDownload Slides
Nowadays, the power and performance scaling benefits following Moore’s Law are diminishing due to the power wall and the utilization wall. This has led to the increasing popularity of heterogeneous computing systems, which integrate CPUs with hardware accelerators such as GPUs, ASICs or FPGAs. Among the hardware accelerators, FPGA is considered as one of the most promising candidates due to its overall advantages in performance, power and reconfigurability. CPU-FPGA heterogeneous systems like IBM Power 8 and Intel HARP, where parts of an application can be accelerated on FPGA, are gaining increasing interest. However, how to best explore the memory hierarchy of such integrated systems to achieve the best bandwidth efficiency remains a challenging problem. This talk will introduce the simulation platform we have developed to support a fast architectural exploration of the memory hierarchy and the interesting findings we made related to the trade-offs for different architectures.
Dr. Wei Zhang received her PhD from Princeton University with Wu Prize. She is currently an Associate Professor with the Department of Electronic and Computer Engineering, the Hong Kong University of Science and Technology, where she established the Reconfigurable System Laboratory. She was an Assistant Professor with the School of Computer Engineering, Nanyang Technological University, Singapore, from 2010 to 2013. Dr. Zhang currently serves as an Area Editor of Reconfigurable Computing of the ACM Transactions on Embedded Computing Systems (TECS), Associate Editor of the IEEE Transaction on Very Large Scale Integration (TVLSI) Systems, and Associate Editor of the ACM Journal on Emerging Technologies in Computing Systems (JETC). She also serves on many organization committees and technical program committees, including DAC, ICCAD, ASPDAC, CASES, FPL, etc. She authored over 80 technical papers in referred international journals and conferences, and authored three book chapters. Her current research interests include reconfigurable system, power and thermal management, embedded system security, and emerging technologies.
