摘　　要：近年来航天测控任务出现了测控目标多,信息传输量大,工作模式多样化等特点,为了满足实际测控任务中对设备的处理能力和灵活性的更高要求,该文实现了一种基于CPCI的动态可重构系统设计。在基带设备中通过应用程序将配置文件由CPCI总线根据需要实时写入到信号处理板上,并由主控FPGA将配置数据加载到核心处理器件FPGA和DSP中。与传统的FPGA和DSP加载方式相比,这种方法可以在极短的时间实现基带设备不同功能和模式的快速切换,不仅节约了硬件资源同时也使系统具有较大扩展性和灵活性,能够满足不同应用需求。该文给出这种可重构系统的详细设计和工程中的典型应用,该设计已经在实际中应用并取得理想的效果。In recent years,many features of multi-target,large amount of information transmission,and diversification of work mode have appeared in aerospace tracking and control tasks. In order to meet the higher requirements of the device processing capacity and flexibility in actual observation and control tasks,the design of dynamic reconfigurable system based on CPCI is realized in this paper. In the baseband device,the configuration files are written on the signal processing board through CPCI bus in real time according to requirements,and then the layout data is loaded to FPGA and DSP by main-control FPGA. Compared with traditional loading modes of FPGA and DSP,this method can realize the fast switch of different functions and modes of base band equipment in very short time. It not only saves the resources of system,but also make the system have greater expansibility and flexibility. The design of this kind of reconfigurable system is discussed in detail and the typical application in practical project is given in this paper,which has achieved an ideal effect in practical work.
