直接数字频率合成器的设计及FPGA实现

Design of DDS and Implementation with FPGA

直接数字频率合成器(DDS)通常使用查表的方法实现相位和幅值的转换,文章介绍了一种基于CORDIC算法的DDS。CORDIC算法在三角函数合成上有着广泛的用途,作者从DDS的一般结构和CORDIC算法的基本原理出发,深入探讨了基于CORDIC算法的DDS各部件的结构和FPGA实现。

This paper introduces a method to design the DDS based on the CORDIC algorithm. The CORDIC algorithm is widely used in complex function generator. The author introduces the principles of DDS and CORDIC algorithm, and moreover discusses the architecture of DDS based on CORDIC algorithm and the implementation on FPGA.
