Magnetic Logical Transducers
Abstract
A method is presented for the logical design of single-stage, combinatorial switching circuits of n-variables. It is applicable to circuits composed of threshold devices, such as magnetic cores, transistors with Kirchoff adder inputs, parametrons, etc. A study of the constraints imposed by the form of the input portions of the threshold devices leads to the definition of certain classes of functions, physically realizable in a single device. With this method, arbitrary switching functions of as many as seven variables were easily designed by hand computations. An algorithm for mechanizing Boolean switching functions, by means of a net of magnetic toroidal cores, is described. The algorithm is referred to as Simplex which, in this application, is programmed for a digital computer. Computer-derived solutions specify the wiring configuration for a core or net of cores yielding a device for performing combinatorial logic. Switching functions are realizable in essentially one clock time. An updated bibliography is included.
