4.19. AXI-Streaming Interface
The IP uses an AXI4 Streaming interface for transporting header and data information to and from the application logic. The header and data are presented as separate interfaces. The PCIe header, PF Number, VF Number, BAR number and Prefix information are grouped as a 32-byte header on the AXI Streaming interface.
- HIP Native mode (only for R-Tile)
- Non-HIP Native mode
- Simple packing mode
- Compact packing mode
The HIP Native mode packing scheme is only available when you choose R-Tile. In this packing scheme, the AXI-ST Transmit and Receive interfaces follow all the rules that the AVST interface of the Native Hard IP follows for packing TLPs.
The compact packing scheme allows the header to be available in fixed locations. This is applicable to P/F/R-Tiles.
Refer to Application Packet Interface for details on how the application user logic must handle this interface in each of the configurations and modes.
