Abstract
A digital networking system includes a digital crosspoint switch, a host controller, and a data processing card that includes a programmable logic device such as a field-programmable gate array (FPGA). The host controller is operative to configure both the data processing card and the digital crosspoint switch in accordance with commands received over a user interface. The system is configurable to direct incoming data through the crosspoint switch to the data processing card for processing, and then back through the crosspoint switch for distribution to one or more network ports. The processing performed by the data processing card may include, among other options, feed filtering of a digital market data feed for use in high-frequency trading applications.
