Abstract The present invention relates to a digital parallel square-function data processor. The processor has a parallel N-bit word input and a parallel 2N-bit output for providing an output corresponding to the square of the value of an input address applied thereto. The processor is comprised of a square function ROM having an address input which is responsive to the parallel input, and a read-out coupled to the parallel output but for two output lines of the parallel output. A coincidence gate is provided having one input which is responsive to an end bit of a combination of parts of the parallel input and further having a second input which is responsive to a preselectively biased balance of the combination of parts of the parallel input. A unit is provided for doubling the digital value of the output of the gate. An adder is provided for additively combining the doubled output with the output of the ROM.
