4.2. Functional Description

For the DisplayPort SST parallel loopback with AXI4-S video interface design example.
Figure 11.  Agilex™ 3 and Agilex™ 5 DisplayPort SST Parallel Loopback with AXI4-S Video Interface
  • In this variant, the DisplayPort source and sink parameter, select AXIS-VVP FULL in Enable Active Video Data Protocols to enable AXI-Stream Video Data Interface.
  • The DisplayPort sink receives video and or audio streaming from external video source such as GPU and decodes it into parallel video interface.
  • The DisplayPort Sink converts video data stream into AXI4-Stream video data and drives the DisplayPort source AXI-Stream video data interface through video and vision Frame Buffer IP. The DisplayPort Source then converts AXI-Stream video data into DisplayPort main link before transmitting it to the monitor.
Note:
  • Because of restrictions of the Agilex™ 5 Modular Development Kit, the FPGA clock routes are not sufficient to support both the EMIF and SystemPLL transceiver modes simultaneously. This limitation does not apply to the Premium development kit.
  • When targeting the Agilex™ 5 Modular Development Kit, turning on System PLL in the design example GUI generates an error message. The design example does not support this combination, because of device routing limitations.
