the Zynq® UltraScale+ MPSoC PS DDR memory. The Video Frame Buffer IP can write a
variety of video formats to the Zynq UltraScale+ MPSoC PS DDR memory.
DP TX Display Pipeline
The DP TX display pipeline (see Figure 5-7) is configured to read video frames from
memory via two separate channels: one for video, the other for graphics. The video and
graphics layers are alpha-blended to create a single output video stream that is sent to the
monitor via the DisplayPort controller. This design does not use the audio feature of the
DisplayPort controller, therefore it is not discussed in this user guide. The major
components used in this design, as shown in the figure, are:
• DisplayPort DMA (DPDMA)
• Audio/Video (A/V) buffer manager
• Video blender
• DisplayPort controller (DP TX)
• PS-GTR gigabit transceivers
The DPDMA is a 6-channel DMA engine that fetches data from memory and forwards it to
the A/V buffer manager. The video layer can consist of up to three channels, depending on
the chosen pixel format, whereas the graphics layer is always a single channel. The used
pixel formats are described in Video Buffer Format. The remaining two channels are used
for audio.
The A/V buffer manager can receive data either from the DPDMA (non-live mode) or from
the PL (live mode) or a combination of the two. In this design, only non-live mode is used
for both video and graphics. The three video channels feed into a video pixel unpacker and
the graphics channel into a graphics pixel unpacker. Because the data is not timed in
non-live mode, video timing is locally generated using the internal Video Timing Controller.
