基于System Generator的CORDIC算法DDS的FPGA实现

Based on the CORDIC Algorithm for the FPGA Realization of DDS with System Generator

基于DDS(直接数字频率合成器)的原理,采用XILINX公司的软件system generator,搭建了基于CORDIC算法的全流水线DDS系统,它不仅比传统查找表式的DDS系统节省了大量存储器资源,达到较高的运算速度,而且利用较新的DSP工具实现了系统的快速设计。

On the DDS （direct digital frequency synthesizer） in principle, the paper built a full piple-line DDS system on the base of CORDIC algorithm with XILINX＇s software-system generator. The method not only saves more Roms than the graditional method of look-up table, but also achieves higher computational speed. The relatively new DSP tool also achieves rapid design of the system.
