Abstract (in Japanese) (See Japanese page) 
(in English) The feature of low latency is becoming important for applications of Stream Data Processing (SDP) such as HFT, and so is matching engine in the stock exchange. Then, we begin to study the method to execute SDP with low latency on FPGA with taking up the zaraba method, a dominant process of matching engine to trade stocks as benchmark. Toward this purpose, there are two issues for the procedure to the table called “Board Information” in which data of unmatched stock orders are accumulated. that is, to determine top priority data fast for matching engine and to pipeline the procedures for consecutive orders. For these issues, we applied heap sort algorithm to this procedure, and developed the novel pipelined heap sort algorithm that can deal with large scale “Board Information”. We evaluated the latency of the zaraba method through register transfer level (RTL) simulation by using sample order data, and it was 0.10μs on average for 5M input orders/s.
