| 摘 要： | DDS波形发生器的设计原理分为两个部分,即PC机部分和FPGA模块部分。其中,PC部分采用DELPHI语言完成设计,经串口向FPGA发送波形以及频率参数;FPGA部分由VHDL语言完成,作为系统的控制核心,根据接收到的波形以及频率参数信息,采用DDS产生相应的波形。

| Abstract: | This paper introduces the theory about how to design DDS wave generator,the system of which is divided into two parts： PC part and FPGA module part. The design about PC part is accomplished by DELPHI language. The parameter of wave form and frequency is sent to FPGA module by PC part. The part of FPGA module by the way of the control core is designed by using VHDL. And at the same time FPGA generates relevant wave by using DDS theory according to the information about the parameter of wave and frequency received from PC part. |
