CORDIC（Coordinate Rotational Digital Computer，坐标旋转计算机）算法是Volder于1959年在美国航空控制系统的设计中提出来的，它是一种用于计算运算函数的循环迭代算法。其基本思想是用一系列与运算基数相关的角度的不断偏摆，从而逼近所需旋转的角度。-On CORDIC (Coordinate Rotational Digital the Computer, coordinate rotation computer) algorithm by Volder in 1959 in the U.S. air traffic control system design, it is the loop iteration algorithm for computing the arithmetic function. The basic idea is the constant deflection angle series and computing base, thus approaching the angle of rotation required.
