摘要
在介绍基本CORDIC算法原理的基础上,提出了一种改进型CORDIC算法。该算法针对三角函数的对称性,分别对输入角度进行了预处理,对迭代结果进行了后处理,实现了整个周期(-π^+π)的三角函数计算。经过仿真分析,验证了设计的正确性和可行性。
In this paper,an improved CORDIC algorithm is described,which is based on introducing of the theory of CORDIC algorithm.Contrapose the symmetry of trigonometry,this algorithm achieves a full cycle（-π ~ ＋ π） of the trigonometric calculations by pre-processing input angles and post-processing iterated results.The validity and feasibility are verified through software simulation.
