Abstract
A method for using an FPGA to implement a crossbar switch is described. Rather than using signals routed through the general FPGA routing resources to control connectivity of the crossbar switch, the input signals only carry crossbar switch data, and the connectivity is controlled by FPGA configuration data. The crossbar switch is implemented in two parts: a template of basic and constant routing to carry input signals through the switch array in one dimension and output signals from the array in another dimension, and a connectivity part controlled by a connectivity table or algorithm to generate partial reconfiguration bitstreams that determine which of the input signals is to be connected to which of the output signals.
