摘　　要：针对嵌入式系统中大图形显示、高分辨率视频播放难的问题,基于ARM处理器和多媒体协处理器SM501提出了一种高效可行的解决方案,给出了硬件模型和实现方法。经过测试对比,此系统较传统的嵌入式系统具有明显的优势,较完美地解决了嵌入式系统中难以进行大图形显示和高分辨率视频播放的问题。此设计思想和方法不仅仅局限于S3C2440处理器,还同样适合目前ARM系列所有处理器,是解决嵌入式系统大图形显示、高分辨率视频播放的一种新途径。Presents an effective solution based on ARM and SM501 to realize large - sized static graphic image displaying and high - resolution full - motion video playing. A feasible method and hardware model is described as well. After testing, can see that the system has obvious advantages compared with traditional embedded system, it resolves the problem of displaying large - sized static graphic and high-resolution full - motion video playing perfectly. This solution is not only suitable for S3C2440, but also suitable for all ARM processors at present, This is a new way to solve the problem of displaying large - sized static graphic and high - resolution full - motion video playing.
