Customizable Display Controller with composition support

CDC is a fully Customizable Display Controller IP core family supporting the OpenWF display API specification. Several features can be configured at synthesis time and controlled at run time via a register interface and easy to use software driver. The display controller can be applied to e.g. FPGA systems with a resource optimized, application specific feature configuration or to ASIC projects applying a more generic feature set and thus more flexibility.

优势

The main functionality of CDC is reading images (layers) from memory, combining them on-the-fly e.g. by blending, cropping and windowing and generating a video output stream of the combined image. CDC supports image compositioning as well as partial screen updates. The output interface of the CDC is compliant with the MIPI-DPI standard and can be easily connected with any video output controller such as HDMI-, MIPI-DSI- or 3G-SDI controllers.
