2.7 CAMERA INTERFACE OPERATION

2.7.1 INPUT/ OUTPUT DMA PORTS

Each CAMIF consists of two DMA ports, namely, Input DMA Port and Output DMA Port. From the view of system
bus, both the ports are independent. The Input DMA port reads the image data from memory. On the other hand,
the Output DMA port stores the image data into memory. These two master ports support various digital
applications such as Digital Steel Camera (DSC), MPEG-4 video conference, video recording, and so on.
