21.3. Full-Raster to Clocked Video Converter Block Description
The clocked video bus can contain additional side-band signals, such as discrete 16-bit signals for the width and height of the raster. The IP ignores these side-band signals. The IP copies some signals from CPU registers. The sideband signals provide backward IO interface compatibility between this IP and legacy Intel clocked video input and clocked video output interfaces.
The figure shows how mapping separates the discrete signals used by the clocked video protocol from the single AXI4-S tData bus. You need a processor interface to construct the legacy Intel clocked video input and clocked video output signals.
