Is FPGA Useful for Hash Joins? Exploring Hash Joins on Coupled CPU-FPGA Architecture
Summary: Empirical exploration of hash-join acceleration on coupled CPU–FPGA (shared-memory) using OpenCL HLS and a roofline-guided analysis to identify optimal CPU/FPGA workload partitioning. Finds FPGA benefit constrained by system memory bandwidth and forecasts needed CPU–FPGA architectural features for DB workloads. (summarized by gpt-5-mini on Feb 09 2026)
