Investigation of the Multiply-add Operation on the Baikal-T Processor

Abstract

This article is devoted to the study of the efficiency of the multiply-add operation instruction on the Baikal-T processor. Various examples of using the command are considered, measurements are made and conclusions are formulated in which cases the use of multiply-add operation gives a gain in calculations and in which situations the use of the command is unprofitable in terms of program execution speed.
