Abstract
A non-blocking crossbar switch architecture circumvents the problem present in prior art crossbar switches where input signals may oversubscribe the available inter-die bandwidth. The new non-blocking crossbar switch architecture is split across a plurality of semiconductor dice, including a plurality of interleaved crossbar switch segments. Only one crossbar switch segment is implemented on each semiconductor die. A plurality of input ports and output ports are coupled to the crossbar switch. The crossbar switch is non-blocking, i.e., any one output port not currently receiving data may receive data from any one input port.
