Optimization of beam pointing algorithm based on PowerPC

Abstract

Based on PowerPC architecture, this paper proposes an optimization strategy of beam pointing algorithm, which is realized from the trigonometric function calculation optimization, floating point arithmetic optimization, loop nesting optimization, and PowerPC instruction optimization. Through the optimization algorithm proposed in this paper, the processing time of the algorithm is reduced to one tenth of the original. At the same time, the optimization strategy proposed in this paper also has certain guidance and reference for the algorithm development and optimization of other platforms.
