Abstract :
Abstract—The operation speed of a one-dimensional, unilateral, iterative switching network with strictly combinational cells is often drastically limited by the propagation delays of carry variables. In this paper an attempt is made to extend to other iterative networks the scheme of a fast carry-propagation circuit proposed by several authors for parallel adder. The class of the networks which are realizable according to this scheme is small but contains many networks of practical interest.
