SDRAM Address Space
The SDRAM address space is up to 4 GB. The entire address space can be accessed through the
FPGA-to-HPS SDRAM interface from the FPGA fabric. The total amount of SDRAM addressable from
the other address spaces can be configured at runtime.

MPU Address Space
The MPU address space is 4 GB and applies to addresses generated inside the MPU.
The MPU address space contains the following regions:
• The SDRAM window region provides access to a large, configurable portion of the 4 GB SDRAM
address space.
The address filtering start and end registers in the L2 cache controller define the SDRAM window
boundaries. The boundaries are megabyte-aligned. Addresses within the boundaries route to the SDRAM
master. Addresses outside the boundaries route to the system interconnect master.

L3 Address Space
The L3 address space is 4 GB and applies to all L3 masters except the MPU. The L3 address space has more
configuration options than the other address spaces.
