AT91SAM9G20 Preliminary
Memory Interface
DMA Features
Dedicated FIFO are used to support packed memory mapping. YCrCb pixel components are
sent in a single 32-bit word in a contiguous space (packed). Data is stored in the order of natural
scan lines. Planar mode is not supported.
Unlike preview datapath, codec datapath DMA mode does not support linked list operation. Only
the CODEC_DMA_ADDR register is used to configure the frame buffer base address.
