Abstract :
A conservative logic element (CLE) is a multiple-output logic element whose weight of an input vector is equal to that of the corresponding output vector, and fan-out of each output terminal is restricted to one. A CLE is a generalized model of magnetic bubble logic elements, etc. In order to realize an arbitrary function, it is necessary to use constant-supplying elements (CSE´s). In this correspondence, we consider the universality of CLE´s in relation to the number of CSE´s.
