基于FPGA直接数字频率合成器DDS的设计

本文利用FPGA器件实现了DDS系统中的关键部分DDS核,所设计的DDS核,由相位累加器和波形数据表组成,可以实现产生任意波形。FPGA器件作为系统控制的核心,其灵活的现场可更改性,可再配置能力,对系统的各种改进非常方便,在不更改硬件电路的基础上进一步提高系统的性能。

Direct Digital Frequency Synthesis Design Beased on FPGA

Direct Digital Synthesis(DDS) technology uses an all-digital synthesis methods,FPGA devices using the DDS System to achieve a key part of the nuclear DDS,DDS designed nuclear,by the phase accumulator and the waveform data table that can generate arbitrary waveform to achieve the purpose.The DDS core is based on the VHDL language QuartusII tools in the environment,as well as complete the design simulation.FPGA device as the core system control,Tan also further improve the performance of the system.
