摘　　要：基于PowerPC架构提出了一种波束指向算法的优化策略,分别从三角函数的速算优化、浮点数运算的优化、循环嵌套优化、基于PowerPC指令集的优化等方面来实现。通过提出的优化算法,算法处理时间缩短为原来的十分之一。提出的优化策略对其他平台算法开发和优化也具有一定的指导和借鉴意义。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.
