| Abstract: | In order to capture and record GJB1188A 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 designed 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 achieves 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. |
