+title: Xilinx ZynqMP DisplayPort Subsystem
+
+description: |
+  The DisplayPort subsystem of Xilinx ZynqMP (Zynq UltraScale+ MPSoC)
+  implements the display and audio pipelines based on the DisplayPort v1.2
+  standard. The subsystem includes multiple functional blocks as below:
+

+                                                 Blended Video and
+                                                 Mixed Audio to PL
+
+  The Buffer Manager interacts with external interface such as DMA engines or
+  live audio/video streams from the programmable logic. The Video Rendering
+  Pipeline blends the video and graphics layers and performs colorspace
+  conversion. The Audio Mixer mixes the incoming audio streams. The DisplayPort
+  Source Controller handles the DisplayPort protocol and connects to external
+  PHYs.
+
+  The subsystem supports 2 video and 2 audio streams, and various pixel formats
+  and depths up to 4K@30 resolution.
