XDMA mode enables the use of PCIE Controller 0 with the XMDA enabled. XDMA mode provides two connectivity variants: AXI Streaming and AXI Memory Mapped. Only one variant can be enabled at a time.

AXI Streaming
XDMA Streaming mode can be used in applications where the nature of the data traffic is streaming with source and destination IDs instead of a specific memory address location, such as network accelerators, network quality of service managers, or firewalls.
AXI Memory Mapped
XDMA Memory mapped mode can be used in applications where the nature of the data traffic is addressable memory, such as moving data between a host and a card as an acceleration platform.

XDMA mode can be used in conjunction with AXI Bridge mode. For more details on AXI Bridge mode, see the AXI Bridge Subsystem.
