ABSTRACT:
A bubble logic array with n data inputs for performing any Boolean (or switching) logic function. Each of the data inputs comprises binary information in the form of the presence or absence of discrete bubbles. The logic function is performed by the propagation, channeling, and interaction of the bubbles themselves. The particular logic function performed by the array may be fixed by permanent connections of selective control inputs to bubble generators. Alternatively, a universal logic array may be provided by using a further 2.sup.n bubble inputs as controls to separately personalize the array. In this manner, the logic function performed by the array may be varied with each set of controls to achieve dynamically alterable logic. When the data inputs each comprise an input bubble pattern the logic array in either the fixed form or the alterable form is capable of pipelining operations, producing one meaningful output at every bit cycle.
