Introduction
DCI is used to receive high-speed data streams from CMOS camera. It supports
different data formats and is applicable to black-and-white cameras, X24
cameras and so on.
Main characteristics
Synchronous parallel interface
Can receive 8/10/12/14-bit data
Supported data format:
YCbCr4:2:2 line-by-line video
RGB565 line-by-line video
Compressed image (JPEG)
8/10/12/14-bit line-by-line video
The edge polarity of the pixel clock can be selected to capture data
The data is transferred through DMA and the buffer is managed by DMA
There are two synchronization methods
Hardware synchronization: HSYNC signal and VSYNC signal
Software synchronization (only support 8-bit parallel data): Embedded
code in data stream
