The configure file is downloaded into the fpga chip according to the fpga design fl ow . also a test system is set up , and the work status of the system is controlled by single chip to download the data of initial registers and control registesr . and the logical analyzer is used to sampling the output signals 使用xillinx的fpgaxc2550pq208 ，经过fpga的实现流程，把配置文件配置到xczs5opqzos ，搭建了一个验证系统，通过单片机来对各控制寄存器写入控制字来控制系统的工作状态，用逻辑分析仪采集输出的信号。
Making use of the powerful capabilities of the pci chip , high - speed data of the dsp platform are transferred both ways at dma mode , and low speed data such as initialization and configuration information are transferred at direct slave mode . this paper shows in detail the workings of pci9054 , the configuration of its control register , and the writing of platform driver with api functions provided by the manufacturer 利用pci接口芯片的强大功能，本文提出了采用dma模式双向传输dsp平台的高速数据，采用从模式传输初始化信息及配置信息等低速数据，并详细介绍了pci9054的工作方式，控制寄存器的配置以及调用厂商提供的api函数编写平台驱动程序。
