Abstract

People traditionally have considered the number of counters in the critical path as the metric for the performance of a multiplier. This report presents the view that tree topologies which have the least number of levels do not always give the fastest possible multiplier when constrained to be part of a microprocessor. It proposes two new topologies: hybrid structure and higher order arrays which are faster than conventional tree topologies for typical datapaths.
