Abstract


In order to improve the interoperability between the aircraft / store , China developed GJB1188A \Monitor and record GJB1188A interface data function data logger to reproduce , the paper developed in order to realize the data interaction between the aircraft and the hangings records provide debugging tools for aircraft / store system , will have a very important significance and broad the application value . Depth to study GJB1188A interface standard based on the functionality and performance requirements , based on the the DSP FPGA overall design , hardware and software design . Hardware design , based on the overall program , DSP, FPGA, video codecs , 1553B bus transceiver and network transceiver device selection ; DSP ??peripheral circuit and interface circuit according to the system requirements , design ; using DM642 rich peripheral resources, design of a video input and output circuits , the the 1553B signal acquisition circuitry, network interface circuitry and a hard disk interface circuit . At the same time , developed the 1553B interface logic and digital I / O interface logic and other decoding logic inside the FPGA . Software design , software reference framework RF5, real-time multi-tasking operating system DSP / BIOS , the main program of the system is designed . Driver Development Kit the DDK , developed a video processing program , and the algorithm of the TI company , and the video data processing . Network program kit NDK, using TCP communication mode , and the development of a network communication program . At the same time , the development of the 1553B signal acquisition , digital I / O signal acquisition and hard disk storage procedures . Finally , the system has been tested and given the results . The test results show that the design of this article is correct and feasible , stable operation of equipment to meet the design requirements .
