The AXI master interface can be connected to an AXI interconnect for accessing system memory through a memory controller. The interface can also be connected directly to any other AXI slave in the system.
The AXI master interface complies with the AMBA 4 AXI4 protocol. See the Arm® AMBA® AXI and ACE Protocol Specification for more information.
In Pass-through mode, all AXI transactions that are received on the AXI slave interface go to the AXI master interface without any modification.
In Translate mode, the interface issues internally generated read transactions to fetch translation data. See 4 Scatter list for more information.
