8.2.1.4. SDRAM Address Space

The SDRAM address space is up to 4 GB. The entire address space can be accessed through the FPGA‑to‑SDRAM interface from the FPGA fabric. The total amount of SDRAM addressable from the other address spaces varies.

There are cacheable and non-cacheable views into the SDRAM space. When a master of the system interconnect performs a cacheable access to the SDRAM, the transaction is performed through the ACP port of the MPU subsystem. When a master of the system interconnect performs a non-cacheable access to the SDRAM, the transaction is performed through the 32-bit main L3 interconnect master of the SDRAM L3 interconnect.
