DisplayPort RX Subsystem - The AXI4-Stream interface is not following the specification for the data width

Description

In the following configurations, the AXI4-Stream interface of the DisplayPort RX Subsystem is not following the AXI4-Stream specification for the data width as it can have a width which is not a multiple of bytes:

Lane Count
Bit Per Color
AXI4-Stream data width
1
1030
11236
21060


As per the AXI4-Stream specification: "The width of the data payload is an integer number of bytes."


Solution

This is a known limitation of the DisplayPort RX Subsystem.

If you have issues with this limitation, a work-around is to use a AXI4-Stream subset converter and force the width of the input and output interfaces.
