20Gbps C-Based Complex Event Processing

This paper presents the world´s fastest complex event processing system, designed to process a large number of events on FPGAs. Unlike conventional SQL-based approaches, our approach features logic automation constructed with a new C-based event language that supports regular expressions on the basis of C functions, so that a wide variety of event-processing applications can be efficiently mapped to FPGAs. Evaluations on an FPGA-based NIC show that we have achieved 20Gbps event processing performance in a financial trading application with only a small logic increase, 2.7%.
