Abstract:The design of video processing module based on ADSPBF561 is discussed.According to the design requirement,ADSPBF561 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 ADSPBF561.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. |
