基于System Generator的数字下变频实现

The implementation of digital down-conversion based on the System Generator

System Generator for DSP是Xilinx公司开发的基于Simulink的图形环境的DSP开发工具,充分利用了Simulink在DSP系统构建中的便利性。本文将以数字下变频为例介绍SystemG enerator的设计流程,设计者不需要了解硬件描述语言(HDL)以及开发平台的细节。实验证明该方法具有操作简单、设计灵活、效率高等优点。

The System Generator for DSP（ Digital Signal Processing）, developed by Xinlinx Inc. , is a development tool based on the graphic environment of Simulink. It makes full use of the advantage of Simulink in constructing the DSP system. The design flow is introduced by taking the digital down-conversion （DDC） as an example. It is not a necessity for a designer to have in-depth understandings of both a hardware description language （HDL） and the particulars of hardware platform development. The experiment has testified that this method has many advantages, such as simple operation, flexible design, and high efficiency and so on.
