This patent describes a single instruction multiple data processor comprising: processing elements, interconnected in a Cube Connected Cycle Network design and using interprocessor communication links which carry one bit at a time in both directions simultaneously; controller means for controlling processor elements which feeds each of the processor elements identical local memory addresses, identical switching control bits, identical Boolean function selection codes, and distinct activation control bits, depending on each of the processor's position in the cube Connected Cycles Network in a prescribed fashion; and input/output devices connected to the network by switching devices wherein, each of the processing element comprises: two single-bit accumulator registors (A, B); two Boolean function generator units, each of which computes any one of 2/sup 8/ possible Boolean functions of three Boolean variables as specified by Boolean function codes sent 2 at a time by the controller to each of the processing elements; and switching circuit means controlled by the controller which select the three inputs to the logic function generators.
