摘　　要：在传统CORDIC算法基础上,提出一种基于FPGA平台的改进型并行CORDIC算法,利用FPGA/CPLD作为硬件平台,增加做为流水线的存储器,把需要旋转的角度设置在一定范围内,实际应用时只需将输入变量和参数设为特定值,就可通过若干次简单加法及位移操作实现所需的运算函数。该算法在Quartus2软件环境下进行仿真,结果证明其能提高计算精度及变换速度。On the basis of traditional CORDIC algorithm, propose an improved parallel CORDIC algorithm in FPGA platform, which use FPGA/CPLD as a hardware platform, increase the memory as a pipeline, and set the angle of rotation within a certain scope, the actual application only need to input variables and parameters as a specific value, while through several simple additions and displacement operations, required computing functions can be achieved. The algorithm is simulated under quartus2, and the results prove that it can improve computing accuracy and transformation speed.
