A system includes arithmetic logic units, each including two 2:1 multiplexers, one 8:1 multiplexer, and a three input majority gate. Each 2:1 multiplexer provides a specific one of two data inputs when a select input signal is at a specific one of two binary states. The 8:1 multiplexer provides output signals indicative of specific ones of eight data inputs in accordance with the binary states of three select input signals. Electrical signals indicative of two input variables are coupled, respectively, to the select input of the two 2:1 multiplexers. Two outputs therefrom are coupled to two of three select inputs of the 8:1 multiplexer, and to two inputs of the majority gate.
