摘　　要：文中先介绍了Xilinx公司FPGA从并配置模式的工作原理,随后介绍在实际的工程项目中,利用项目自身的数字图像实时处理系统内DSP+FPGA结构,实现Xilinx公司V5系列FPGA更高级配置应用—使用DSP和CPLD配合工作,完成数字图像处理系统中XC5VLX50 FPGA的从并配置。针对FPGA动态配置,从电路硬件设计和软件实现两方面详细讲述了配置工作的具体过程和实现步骤。这种FPGA动态配置方式优点是利用图像处理系统板级现有资源,在尽量少的空间实现尽量多的功能,同时减少元器件数量和增加系统的灵活性。In this paper,first operation principle of FPGA of Xilinx slave SelectMAP configuration is introduced. Then in the actual engi-neering project,using the digital image real-time processing system of DSP＋FPGA structure in project itself,realize the Xilinx company V5 series FPGA more advanced configuration application - DSP and CPLD cooperation,to complete the slave SelectMAP configuration of digital-image-processing system. In view of dynamic configuration of FPGA,the procedure and realization steps are explained from two aspect of hardware design and software realization. The advantage of the way of FPGA dynamic configuration is to use resource of image processing system,in the space of less as far as possible realizing the function of as much as possible,at the same time,the way can reduce number of component and increase flexible of system.
