Non-coherent traffic from fabric agents follows a 256-bits AXI F2SDRAM port based direct path to DRAM through the MPFE wrapper. Coherent traffic uses a 256-bits ACE-Lite or ACE5-Lite F2H port which leads the transaction into the cache coherent CCU interconnect within the application processor subsystem (APS) partition.

53 You can use the Altera ACE5-Lite Cache Coherency Translator IP to connect any AXI or Avalon® memory-mapped FPGA Manager in the fabric to the F2H bridge. For more information about this IP, refer to the Embedded Peripherals IP User Guide .
