ABSTRACT:
Disclosed is an improved parallel processing system using a radial bus assembly comprising a stack of disks each having an integrated circuit crossbar switch fixed at its center, a plurality of communication lines of equal length radially extending from the communication terminals of the crossbar switch and terminating on the circumference of the disk, a plurality of control lines each being arranged between adjacent communication lines, and radially extending from the control terminals of the crossbar switch and terminating short of the circumference of the disk, and male-and-female joints to electrically connect the terminations of the control lines of all disks in terms of same angular positions longitudinally in common. This arrangement permits substantial reduction of disk size by shifting the control terminals from the circumference of the disk to the inside space thereof, thus accordingly reducing the whole size of the laminated cylindrical bus structure, and hence increasing the data transfer speed on shortened radial communication lines.
