AXI4-Stream output interface. For more information, see the HDMI 1.4/2.0 Receiver
Subsystem Product Guide (PG236) [Ref 12].
• The Video Processing Subsystem (VPSS) is a collection of video processing IP subcores.
In this design, the VPSS uses the Video Scaler only configuration which provides
scaling, color space conversion, and chroma resampling functionality. The VPSS takes
AXI4-Stream input data from the HDMI RX Subsystem and depending on the input
format and resolution, converts and scales it to the desired output format and
resolution again using AXI4-Stream. A GPIO is used to reset the subsystem between
resolution changes. For more information, see the Video Processing Subsystem Product
Guide (PG231) [Ref 13].
• The Video Frame Buffer Write IP uses the same configuration as the one in the TPG
capture pipeline. It takes AXI4-Stream input data from the VPSS and converts it to
memory-mapped AXI4 format. The output is connected to the HP1 high performance
PS/PL interface via an AXI interconnect. For each video frame transfer, an interrupt is
generated. A GPIO is used to reset the IP between resolution changes.
Similar to the TPG pipeline, the HDMI RX, VPSS Video Scaler, and Frame Buffer Write IPs are
configured to transport two pixels per clock (ppc), enabling up to 2160p60 performance.
Although the color format and depth at the HDMI RX are determined by the HDMI source,
the VPSS always converts the format to YUV 4:2:0, 8 bits per component (bpc), which is then
written to memory by the Frame Buffer Write IP as NV12 format.
