REVERSIBLE CONVEYER COMPUTATION IN ARRAY OF PARAMETRIC QUANTRONS.

A possibility of physically and logically reversible processing of digital information in Josephson-junction circuits of a reasonable complexity has been considered. As example, 8-bit 1024-point fast convolver has been designed on the basis of a two-dimensional quasi-uniform array of approximately 250 multiplied by 30,000 parametric quantrons. This completely reversible conveyer device can operate with the estimated rate of at least approximately 10**9 numbers per second, which corresponds to approximately 10**1**4 binary logical operations per second. At this rate the power dissipation in the whole device can still be as low as approximately 30nW. A new mode of the parametric quantron operation with larger parameter margins is also described.
