Abstract

Conventionally, for processing multi-legged orders, matching engines were implemented in software and were connected through Ethernet which is very slow in terms of throughput. Such traditional trading systems failed to process orders of tokens on different machines and these were summarily rejected. Present disclosure provides multiple FPGA system being optimized for processing/executing multi-legged orders. The system includes a plurality of FPGAs which are interconnected for communication via a PCIe port of a multi-port PCIe switch. Each FPGA comprise a net processing layer, a matcher, and a look-up table. Each FPGA is configured to process tokens (e.g., securities, etc.). If orders to be processed are for tokens on same FPGA where the order is received, then tokens are processed locally. Else net processing layer of a specific FPGA routes to specific order request to another FPGA where the tokens (securities) are located thereby reducing the latency and improving overall throughput.
