ABSTRACT OF THE DISCLOSURE Disclosed is an improved integrated circuit crossbar switch and a parallel processing system using the same. The crossbar switch comprises a lattice of signal paths each comprising a pair of signal conductors, and a plurality of contacts each arranged on each crossing in the lattice network. Also, each crossing has a control signal line for controlling the opening-and-closing of the contact. The parallel processing system comprises a stack of bus-printed disks each having an integrated circuit crossbar switch just described. A plurality of pairs of communication lines of equal length are printed on each disk, each pair extending from the corresponding pair of signal conductors of the center crossbar switch. Likewise, control lines radially extend from the corresponding control signal lines of the central crossbar switch. Boards each having a processing or switching control unit can be electrically and mechanically connected to the stack of bus-printed disks. Use of a pair of communication conductors for each radial communication path permits simultaneous data transfer between one procesing unit and each of two other processing units, accordingly increasing the processing speed.
