This paper proposes an FPGA-based Stream Data Aggregation for large Sliding-Windows. We designed Configurable Query Processing Hardware (CQPH), which is a dynamically configurable accelerator for real-time query processing on data streams. Previous implementation of CQPH used BRAM on an FPGA to store intermediate data of aggregation, hence it restricts available sliding-window sizes due to the capacity of on-chip memory. We redesigns a new CQPH which utilizes off-chip DRAM for large amount of intermediate data buffering in order to support variety of queries with large window sizes. To reduce DRAM access latency, we introduce two mechanisms, a look-ahead cache and multi-stage compression of intermediate aggregation results. We show that the proposed new implementation of CQPH works well for stream data aggregation on large sliding-window sizes without degrading performance compared with the previous BRAM-based implementation. |
