1.3. Mailbox Client Intel FPGA Core Interface Signals

The host communicates with the Mailbox Client Intel FPGA over its Avalon® Memory-Mapped ( Avalon® MM) interface. For Intel® Agilex™ devices, the AXI manager interface is available if you enabled Enable Crypto Service parameter.

Through the AXI manager interface, the crypto service has access to the lowest 1GB of memory, with a maximum data size of 512 MB per each read and write operation.
The following figure illustrates the Mailbox Client Intel FPGA IP interfaces.
