Abstract

The authors propose a new method for finding the sum of two or more multidigit values in a parallel computational model. The method reduces finding the sum of a large number of multidigit values to the sum of two multidigit values by carry-save addition, which can be efficiently implemented in a parallel computational model based on carry-lookahead addition of groups of words. The algorithms for implementing the operation of finding the sum of values on one processor and on k processors are proposed. The complexity analysis is carried out for the proposed algorithms.
