摘　　要：现代飞机座舱显示技术的发展日新月异,越来越多的视频信息需要在座舱中显示和交互。在某特定的供电显示系统中,既要处理相关视频信息又要严格控制模块的功耗,因此需要研究机载低功耗视频处理技术。结合系统需求,研究了机载低功耗视频处理模块的硬件设计和逻辑软件算法。在机载供电显示系统中实现了视频信号的相应处理,包括视频旋转和视频缩放,同时满足了系统对视频模块的功耗控制要求。Modern aircraft-cabin display technique is developing rapidly, more and more video information needs to be displayed and interacted in the cabin. In a specific power supply display system it is needed to process relative video information and strictly control the power consumption of the module. So it is necessary to research on the avionic low power-consumption video processing technique. Combined with the system requirements, the hardware design and logic software algorithm of the avionic low power-consumption video processing module are studied. In the power and display system, the process of video signals, including video rolling and video zoom is realized, and the power consumption requirement for the video module is met.
