ABSTRACT:
Disclosed is a parallel processing system comprising, in combination, a stack assembly of bus-printed disks and a plurality of processing unit boards standing upright around and electrically connected to the stack assembly of bus-printed disks. Each bus-printed disk has an IC crossbar switch at its center and printed signal conductors radiating from the IC crossbar switch, and terminated with impedance matching elements. A selected processing unit board has an IC crossbar switch controller to allow the switch elements of each crossbar switch to open and close in a predetermined sequence. With this arrangement communication lines of equal, shortest possible length are provided to make a required electrical connection between selected processing units. Thus, reliable, noise-free, high-speed transportation of data is permitted.
