6.5 Video Interfaces
6.5.1 Video Processing Subsystem (VPSS)
The Video Processing Sub-System (VPSS) provides a Video Processing Front End (VPFE) input interface
for external imaging peripherals (i.e., image sensors, video decoders, etc.).
6.5.1.1 Video Processing Front End (VPFE)
The Video Processing Front-End (VPFE) controller receives input video/image data from external capture
devices and stores it to external memory which is transferred into the external memory via a built in DMA
engine. An internal buffer block provides a high bandwidth path between the VPSS module and the
external memory. The Cortex-A8 will process the image data based on application requirements.
