好吧,难道是我问题太奇葩?没人回答啊。。。。
从ti的文档sprugz8e中看到这样一段话:
12.10.2 VIP Functional Description
The video data is captured from the external video source by the VIP Parser sub-block in the VIP block.
The VIP Parser then sends the captured data for further processing in the VIP block which can include
color space conversion, scaling, chroma down-sampling and finally writes the video data to external DDR
memory. Color space conversion, scaling and chroma down-sampling are all optional for the incoming
stream.
The scaler and chroma down-sample module inside of the VIP can also be used for the memory-tomemory
operation if they are not used in the capture mode.
意思是:从外部来的video data到 VIP block后,可进行的操作有color space conversion, scaling, chroma down-sampling ,之后会写进外部DDR.
并且这三个处理流程是可选的。如果在capture mode里不进行 scaling, chroma down-sampling ,那 scaler and chroma down-sample module可用作内存copy。
我的问题又来了:从camera来的raw data,进入VIP block后,可不可以先用scaler and chroma down-sample module进行 memory-tomemory
operation ,把图像行顺序调整后再进行Color space conversion呢?
大神快来,谢谢!!!
