A crossbar switch ( 50 ) is implemented in a reconfigurable circuit, such as a FPGA, instantiated with a number of modules ( 40 ), the crossbar switch ( 50 ) providing communication links between the modules ( 40 ). The modules ( 40 ) and crossbar switch ( 50 ) can be easily updated in a partial reconfiguration process changing only portions of modules ( 40 ) and the crossbar switch ( 50 ) while other portions remain active. The crossbar switch ( 50 ) uses individual wiring to independently connect module outputs and inputs so that asynchronous communications can be used. The crossbar switch ( 50 ) 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.
