Abstract


With electronic technology , multimedia technology , signal processing technology continues to evolve , airborne avionics to the miniaturization of the volume , the development of functional diversification direction ; many airborne equipment and the existence of complex cross-linked to each other , how to design and realization of the kinds of powerful , reliable performance , compact , strong anti-interference ability of the system is an important subject of study to become engineers . The digital video recorder (DVR) as the aircraft is an important device , display control system (DCMS) is responsible for receiving , processing, recording aircraft flight control screen , these records screen information for ground staff flight analysis and assessment provide an important basis . In this thesis, the system requirements analysis , design and development of a video processing system based on TI's DSP chip , the system LVDS technology , video surveillance technology , the digital video technology combination for airborne DVR , completed on airborne video , audio, data acquisition and processing. The articles chosen TMS320DM642 to complete the design and development of video processing systems as the core , described in detail the division of the various functional modules of the system highlights the the TMS320DM642 interface hardware design , module specific hardware circuit and component characteristics , at the same time introduce PCB design should be noted that some of the problems and solutions . The paper also describes the design of the integrated development environment of the system software as well as the corresponding underlying driver and video capture module , external expansion memory module test software source code .
