The subsystem uses the AMD AXI Interconnect IP core as a crossbar, which contains one AXI4-Lite slave interface and two AXI4-Lite master interfaces when HDCP is not enabled in the system. With HDCP enabled, the subsystem has four AXI4-Lite master interfaces.
The following figure shows the AXI slave structure within the DisplayPort RX Subsystem. For more details on the AXI crossbar functionality, see the AXI Interconnect LogiCORE IP Product Guide (PG059).
