摘要: |
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。 |

Abstract: |
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. |
