坐标旋转数字计算机（CORDIC）算法大大提高了数字信号处理算法和其他数学运算的硬件实现效率。针对传统CORDIC算法存在大量冗余迭代的问题，将传统CORDIC算法与VSF CORDIC算法相结合，提出了一种新的高效CORDIC算法。并在Cyclone IV FPGA上进行了仿真实现。结果表明，迭代次数明显减少，同时硬件资源消耗也有所降低。
Coordinate Rotation Digital Computer (CORDIC) algorithm has greatly improved the efficiency of the hardware implementation of digital signal processing algorithms and other mathematical operations. While there exist quite a lot of redundant iterations in the Conventional CORDIC algorithm, this paper proposes a novel efficient modified CORDIC algorithm combining the Conventional CORDIC algorithm with the VSF CORDIC algorithm. And this new method has already been simulated and implemented on Cyclone IV FPGA. The results show that the number of iterations has been obviously reduced while the hardware resource consumption is also decreased to some extent.
