This patent describes a processing element for use in a single instruction multiple data parallel processing system comprising a processing element. The element consists of: an arithmetic/logic unit (ALU) comprising electronic circuitry for performing binary logic operations on signals applied thereto; an exclusive-OR gate coupled to receive a first input signal and apply an output signal to the ALU; memory means for storing a signal, the signal stored in the memory means being outputted to the gate; and the gate providing the output signal to the ALU as the complement of the first input signal only upon a second being stored in the memory means and thereby outputted to the gate, the gate providing the output signal to the ALU as the first input signal in the absence of the second signal.
