Abstract
There is disclosed a switch matrix and operational method relying upon a high degree of operational logic at each matrix crosspoint. In one embodiment, the switch is used in a multiprocessor system arranged as an image and graphics processor. The processor is structured with several individual processors all having communication links to several memories without restriction. The switch matrix serves to establish the processor memory links and the entire image processor, including the individual processors, the crossbar switch and the memories and is contained on a single silicon substrate.
