摘　　要：提出了一种基于 PCI总线的数字下变频模块设计方案 ,它与商业化的 DSP处理板相结合 ,可以构成一个完整的多制式数字接收机。文中首先介绍它的总体结构 ,并分析了其中主要功能模块的工作原理 ,最后着重阐述全局控制器的设计与主控程序的工作流程。A digital down converter(DDC) module is presented based on PCI bus,which can constitute a multi-mode digital receiver when combined with a COTS DSP board. The architecture of the DDC module based on PCI bus is first d escribed. Then the performances of the major parts are analyzed. The design prin ciples of the global controller are described in detail because of its importanc e. At last the control procedure is discussed. The experimental result shows th at the plan is flexible and powerful in many applications.
