Implementation of Ultra High Definition Video Output with Zynq-7000 for CNC Machines and Industrial Equipment

The article presents a method of video output subsystem’s development with an ultra-high resolution (2560 x 1440 pixels and higher) support, a method for assessing the permissible video mode parameters and setting drivers, as well as an example of successful implementation of such a subsystem based on entry-level chips of the Zynq-7000 family. The features of a hardware platform definition in the Vivado environment and the Petalinux operational system configuration and setup are described. The results of the subsystem’s test runs using various video modes are presented, including horizontal and vertical resolution value as well as a frame refresh rate.
