v_axi4s_remapper is used in DisplayPort example
designs to remap video pixels between different “pixel per clock (PPC)” requirements.
Multiple color formats are supported for remap namely, YUV444, YUV422 and YUV420. This
IP is employed in DP TX data pipeline after frame buffer and in DP RX data pipeline
before frame buffer in DP example designs, as the frame buffer always outputs data in
4PPC mode, but Xilinx may require other PPC modes for DP TX and RX.
Apart from “PPC” conversion, this IP also supports pixel drop and pixel repeat features which enables dropping and repetition of user specific pixels on the output and supports YUV420_HDMI color format too, which are out of scope of this document.
Note that this
v_axi4s_remapper is not part of
the DisplayPort protocol requirements and is used only in the example design to assist
users in validation. Hence, Xilinx does not provide
a separate product guide for
v_axi4s_remapper and does
not provide support related to this IP.
