Abstract

A crossbar switch is implemented in a reconfigurable circuit, such as a FPGA, instantiated with a number of modules, the crossbar switch providing communication links between the modules. The modules and crossbar switch can be easily updated in a partial reconfiguration process changing only portions of modules and the crossbar switch while other portions remain active. The crossbar switch uses individual wiring to independently connect module outputs and inputs so that asynchronous communications can be used. The crossbar switch can be implemented in different embodiments including a Clos crossbar switch, and a crossbar switch connecting each module output only to a corresponding module input, allowing for a reduction in the amount of FPGA resources required to create the crossbar switches.
