A specialized coprocessor for calculating trigonometric functions

By Georgitsa Yuri Vasilyevich

Abstract

Principles of representation of a class of trigonometric functions by specialized coprocessors. The work is aimed at development of techniques of accelerated computation of trigonometrical functions and structures of coprocessors for their realization. Bitable-algorithmic technique of accelerated calculation of trigonometric functions, digital analog and analog-digital versions of structures of coprocessors for calculating trigonometric functions are developed. The developed technique and structures of coprocessors for calculating trigonometric functions made it possible to increase substantially the operational efficiency of the simulation complex. The bitable-algorithmic technique of accelerated calculation of trigonometric functions, as well as the principle of application of approximate relations are implemented. The time of calculation of the functions is reduced, the computational process of the trigonometric functions as a whole is simplified. The field of application covers computational systems used on simulationof robotic systems and aircraft control systemsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
