COMPUTING MEDIUM USING THRESHOLD ELEMENTS WITH COMBINED FUNCTIONS,
Abstract
The realizability of a 'computing medium' (i.e.., a homogeneous logic structure whose function may be controlled on command), in which logic and coupling functions are performed jointly, is discussed. Certain logic functions are performed by interaction of a group of computing medium elements. Two variants based on pulsed and dc level signals are presented. They differ in the number of bits which are necessary for changing the structure and, therefore, the function of the elements. For the two cases cited, these quantities are equal to 1 and 5, respectively. The aim of this study is to reduce the number of information bits necessary for control of computing medium elements over that when each element has independent control. This is done by grouping a number of elements to perform the desired functions. In the pulsed threshold system, a refractory period exists when the elements do not react to input signals. Signal transmission and branching are illustrated for this system as well as methods of realizing two-input conjunction, disjunction, storage, and interaction. The level threshold elements, on the other hand do not have a refractory property but nevertheless they are able to perform signal branching, NOR operation, negation, and storage. (Author)
