摘要
介绍了以Altera公司的RISC结构的CPU软核Nios为基础,利用Quartus软件和SoPCBuilder设计的一种精度较高的DDS信号源。介绍了DDS原理和利用Nios进行设计的方法,以Nios作为控制,单片FPGA实现了频率稳定、精度高及频率可调,相位、幅度可调的正弦信号源。
The paper introduces a method to develop a high precise DDS signal source based on CPU soft nucleus Nios of RISC in Altera Company.It introuduces the theory of DDS and the design flow of the Nios briefly, realizes the frequency, amplitude and phase can be adjusted of DDS based on the QuartusⅡ software and SoPC Builder.
