The Zynq UltraScale+ MPSoC also includes a hardened DisplayPort (DP) interface module. The DisplayPort interface is located in the PS and can be multiplexed to one of four dedicated high-speed serial transceivers operating at up to 6Gb/s. This eliminates the need for additional display chips to further reduce system BOM cost. The DisplayPort interface is based on the Video Electronics Standards Association (VESA) V-12a specification and provides multiple interfaces to process live audio/video feeds from either the PS or the PL, or stored audio/video from memory frame buffers. It simultaneously supports two audio/video pipelines, providing on-the-fly rendering features like alpha blending, chroma resampling, color space conversion, and audio mixing. This block also includes a dedicated video Phased-Lock Loop (PLL) for generating sync clocks.
