基于FPGA和DSP的机载高清VGA视频采集系统设计与实现

Design and Implementation of Airborne High-Resolution VGA Video Acquisition System Based on FPGA and DSP

针对某新型机载视频测试需求的迫切性以及目前测试方法和设备不能满足试飞测试需求的问题,以TMS320DM6467T芯片为核心处理单元,采用FPGA和DSP设计技术,完成了机载高清VGA视频采集系统的硬件和软件设计,成功解决了该型机载视频的采集与处理,实现了对该机专用视频采集各要求项目的自动测试功能和自检功能;该视频采集系统已成功得到应用;实践表明,该系统能够满足测试需求,具有测试精度高、运行稳定、可扩展性好等特点。

Aiming at the testing requirement of an airborne video system and the dissatisfactory of the present testing methods and de- vices in the field of flight--testing, The technique of FPGA and DSP is adopted to implement the hardware and software design of the Air- borne High--Resolution VGA Video Acquisition System based on TMS320DM6467. Problems such as the various kinds of video signals and the difficulty of revivification in the field of flight--testing, The required test items of airborne video acquisition are experimented and the self test succeeded. The Airborne High--Resolution VGA Video Acquisition System has been put into practice. It is indicates that Acquisition System could satisfy the self testing requirements of the test system for video signals, and it has the characteristics of high accuracy, reliable performance and being easily extended.
