Abstract: FPGAs have matured over the years and are being used along with multicore and emerging memory technologies to realize advanced platforms to accelerate a variety of applications. This talk will review the promise of reconfigurable computing leading up to current trends in accelerators. We will illustrate FPGA-based parallel architectures and algorithms for a variety of data analytics kernels in advanced networking, streaming graph processing and machine learning. While demonstrating algorithm-architecture co-design methodology to realize high performance accelerators for deep packet inspection, regular expression matching, packet classification, traffic classification, heavy-hitter detection, etc., we demonstrate the role of modeling and algorithmic optimizations to develop highly efficient IP cores. We also show high-throughput and energy-efficient accelerator designs for a class of graph analytics and machine-learning kernels. Our approach is based on high-level abstractions of the architectures and design of efficient data structures, algorithms and mapping methodologies. We illustrate the performance improvements such accelerators offer and demonstrate the suitability of accelerators for these computations. We conclude by identifying opportunities and challenges in exploiting emerging heterogeneous architectures composed of multicore processors, FPGAs, GPUs and coherent memory.
