基于C0RDIC算法的通用调制器的FPGA设计与实现

摘要

The CORDIC algorithm principle is introduced in this paper and a general modulator based on CORDIC algorithm for computing the sine value is designed.The system is structured and simulated by MATLAB/Simulink DSPBuilder and Quartus Ⅱ .The simulation result shows the CORDIC algorithm can reduce hardware circuit and chip area.The feasibility of the structure to general modulator is proved.%介绍了CORDIC算法的基本原理,利用计算正弦值的CORDIC算法设计了通用调制器.使用MATLAB/Simulink、DSPBuilder和QuartusⅡ进行系统模型的搭建和波形仿真实现,结果表明CORDIC算法可以减少硬件复杂度和芯片面积,并验证了本文提出的通用调制器方案是可行的.
