4.7.8
The purpose of the IPU is to provide comprehensive support for the flow of data from an image sensor
and/or to a display device. This support covers all aspects of these activities:
4.7.8.1
There are three camera timing modes supported by the IPU.
4.7.8.1.1
Smart camera sensors, which include imaging processing, usually support video mode transfer. They use
an embedded timing syntax to replace the SENSB_VSYNC and SENSB_HSYNC signals. The timing
syntax is defined by the BT.656/BT.1120 standards.
This operation mode follows the recommendations of ITU BT.656/ ITU BT.1120 specifications. The only
control signal used is SENSB_PIX_CLK. Start-of-frame and active-line signals are embedded in the data
stream. An active line starts with a SAV code and ends with a EAV code. In some cases, digital blanking
is inserted in between EAV and SAV code. The CSI decodes and filters out the timing-coding from the data
stream, thus recovering SENSB_VSYNC and SENSB_HSYNC signals for internal use. On BT.656 one
component per cycle is received over the SENSB_DATA bus. On BT.1120 two components per cycle are
received over the SENSB_DATA bus.
4.7.8.1.2
The SENSB_VSYNC, SENSB_HSYNC, and SENSB_PIX_CLK signals are used in this mode. See
