When configured with the AXI4-Stream video interface, the subsystem is packaged with these subcores:
- DisplayPort Receive core
- DisplayPort Video to AXI4-Stream Bridge
- AXI IIC controller
- HDCP core with AXI Timer when HDCP feature is enabled
In MST mode, the Video to AXI4-Stream Bridge instances increase to the number of video streams in addition to the sub-cores listed in SST.
Because the DisplayPort 1.4 RX Subsystem is hierarchically packaged, the subsystem creates the required hardware after you select the parameters. The subsystem receives video using the DisplayPort v1.4 protocol over a 16-bit video PHY interface. The subsystem works with the Video PHY Controller ( Video PHY Controller LogiCORE IP Product Guide (PG230) configured for the DisplayPort protocol. The subsystem outputs multi-pixel video over an AXI4-Stream interface. The following figure shows the subsystem architecture for MST with four streams.
