Abstract

While FPGAs can offer great throughput and energy efficiency, when offloading OpenMP target regions to them the memory bandwidth often limits the ability to exploit their potential. As a remedy, our OpenMP-to-FPGA compiler fully automatically inserts optimized multipurpose cache blocks into the generated FPGA hardware. We exploit characteristics of OpenMP target regions to both avoid costly bus snooping hardware and to achieve cache consistency. On a diverse set of benchmarks with data reuse the caches reduce the runtime by 43 % on average, while only consuming slightly more FPGA resource.
