Zusammenfassung:	Large-scale scientific computers are characterized by having a high ratio of computing requirements to the input-output requirements. Thus the speed of arithmetic operations should be of prime importance in this group of digital computers. In this note a mathematical formula is derived to determine the multiplication time obtained by each of the known high-speed multiplication techniques. Then a comparative analysis is performed to show the amount of speed improvement resulting from each technique and the influence of the different factors affecting speed.
