摘　　要：为实现GJB1188A接口信号采集和记录,设计了一种基于DSP+FPGA的数据记录仪。硬件上,利用DM642丰富的外设资源,完成了视频采集和回放模块、以太网接口模块和IDE硬盘接口模块的设计;同时,在FPGA内部实现了1553B接口逻辑和数字I/O接口逻辑。软件上,利用DSP/BIOS开发了DM642固化软件,实现了各数据采集通道的管理和控制、硬盘存储及网络传输。该设备运行稳定,符合设计要求。In order to capture and record GJBl188A data, a data recorder based on DSP ＋ FPGA is designed. In this system, the modules of video capture and display interface, EMAC interface and IDE interface are de- signed by the rich peripheral resources of DM642; the modules of 1553B data capture interface and digital I/O capture interface are implemented by FPGA. The driver program is developed based on TI DSP/BIOS, which a- chieves the management and control of the data capture channels, hard disk storage and network transmission. The system works stably and meets the needs of design.
