CDC is a fully Customizable Display Controller IP supporting up to 16k resolutions (4096x4096 pixel) on a MIPI-DPI compliant parallel video output. Several features can be configured at synthesis time and programmed at run time. The main functionality of CDC is reading images (layers) from memory (or – as option in CDC-500 – as AXI4 video input stream), combining them on-the-fly e.g. by blending, cropping and windowing and generating a pixel output stream of the combined image. The CDC supports image composition as well as partial screen updates.
On the output the controller provides a digital MIPI-DPI compliant RGB signal (or optionally a digital component YCbCr signal).
