摘要 介绍了基于ADSP-BF561的视频信息处理模块的设计。系统以ADSP-BF561为核心,控制视频信号的采集、处理和回放。其中,视频解码、编码分别采用ADV7189B、ADV7179芯片实现,其数据并行输出与ADSP-BF561的PPI接口相连,配置接口采用I2C方式。软件的设计包括测试程序及VxW orks下驱动程序。该设计结构紧凑,成本低廉,可靠性高。 The design of video processing module based on ADSP-BF561 is discussed. According to the design requirement, ADSP-BF561 is the core of the system to control the collection, processing and playback of the video signal. The decoding and encoding of the video signal are realized by ADV7189B and ADV7179 separately. The parallel data output of ADV7189B and ADV7179 is connected with the PPI interface of ADSP- BF561. Meanwhile, the software design including the design of driver and test program based on VxWorks is introduced. Finally, the design can process the video information effectively and correctly.
