DISPLAY-CTRL-4K - 4K Digital Cinema Display Controller

4K Cinema Display.PNG

The DISPLAY-CTRL-4K is a synthesizable core intended for use in the AMBA® AXI bus-based microprocessor systems. It is a complete module of a digital video data path, which is transferred directly to the image display device interfaces such as DVI or HDMI transmitters.

The display controller supports a wide range of resolutions in both standard and widescreen formats. The maximum screen size is 8190 by 8191 pixels, and the actual supported resolution depends on target technology.

The standard video data output is the most popular 24-bit per pixel RGB format. However, others formats like 30-bit, 36-bit, 48-bit per pixel or other can be easily implemented according to user requirements.

The data format in which the controller takes information from the system memory and stores in the FIFO is typical two 24-bit pixels per 64-bit data, but other data formats are also supported.
