6.2.1.4. HPS SDRAM Address Space

The SDRAM address space is 128 GB. It is accessed through the FPGA-to-SDRAM interface from the FPGA. Note that the FPGA-to-SDRAM interface provides the only address map that can access the entire 128 GB memory range without gaps.

Figure 24. DDR Address Maps

There are cacheable and non-cacheable views into the SDRAM space. Both views are managed by the MPU (ACE) and FPGA-to-HPS bridge (ACE-Lite) masters.
