CORDIC算法的优化及其硬件实现

Optimized Design of CORDIC Algorithm Based on Hardware

针对采用流水结构实现CORD IC算法时存在的不足,从旋转角度范围、旋转角度精度的调整、模校正因子的分解3个方面进行了详细的分析和讨论,并给出了相应的优化设计和改进措施.实现了基于FPGA的CORD IC算法全流水结构,最后用CORD IC算法实现信号发生器加以验证.

The paper has detailedly analysed and discussed the shortcomings when the pipeline is used to achieve CORDIC algorithm, from the angle of rotation, the adjustable precision of rotation angle and the decomposition of factor correction and given the corresponding optimization and improvement measures. The design has realized the entire pipeline for CORDIC algorithm based on FPGA, and finally tested CORDIC algorithm with signal generator.
