  • Abstract
    A subclass of generalized parallel counters, called parallel compressors, is introduced in this correspondence. Under present-day packaging technology, parallel compressors with their higher compression ratio and fewer input/output pins are more efficient in multiple operand addition and multiplication than parallel counters. Cost and time bounds are obtained for schemes using parallel compressors for reduction of N summands to m summands. Furthermore, a method for synthesizing large parallel counters using only one type of parallel compressor is given.
