显示输出融合在高端智能综合仪器仪表中具有广泛的应用,本文设计了一款通用的多路视频/图像混合器.最多支持四路不同分辨率率、不同类型的视频/图像.包括从VGA到UXGA动态视频、采用轨迹刷新模式的彩色或单色图形视频,也可以是准静态的窗口图像.介绍了该设计的功能定义思路,体系结构,并基于该设计完成了一个测试装置的显示输出系统的设计.讨论了其中的三个关键模块设计方法.包括:1)视频混合模块数据通道设计;2)一个改进的低成本、高质量的视频流缩放器,用于支持对输入视频或输出视频进行分辨率调整;3)一种新颖的外设配置数据加载器,可以替代MCU对外设进行配置载入,降低系统成本.

Output data mixer is used widely in advanced compound instrument more and more. A video/image mixer of multiple inputs was discussed in this paper. At most four video/image inputs of different sizes and formats are supported, including dynamic video from VGA to UXGA, chroma or grey graphics refreshed based on trail addressing, and semi static window images. The whole process of design was introduced, including functional specification, architecture, and some implementation details. As a case study, a display terminal system of a monitoring apparatus was implemented based on the video/image mixer. Design methods of three key modules of the video/image mixer were elaborated, which includes: 1) the data flow of video/image blending, 2) a modified low cost, high quality video/image streaming scaler used for video/image size adjustment, and 3) a novel bus writer for downloading peripheral configuration data, which can take the place of MCU with a great cost saving.
