摘　　要：该文提出了一种基于正余弦流水线CORDIC的模校正因子和级数部分的改进旋转算法,在FPGA仿真中给出了相关实验数据,结果证明了该方法可以有效减少流水级数,降低硬件复杂度,满足计算精度,改进引起的误差精度很小,在实际应用中可以忽略不计。A kind of improved Coordinate Rotation Digital Computer（CORDIC） algorithm is given in this paper,which based on absolute value emendation factor and pipeline progression about sine and cosine calculation.The related date shown in the FPGA simulation experiment verified that the method could reduce the pipe line progression,simplify the complexity of hardware,meet the calculation precision effectively;the error induced by the improved method can be ignored.
