2.4.1. HPS Address Spaces
The following table shows the HPS address spaces and their sizes.
Name |
Description |
Size |
---|---|---|
MPU |
MPU subsystem |
4 GB |
L3 |
System interconnect |
4 GB |
SDRAM |
SDRAM region |
4 GB |
Address spaces are divided into one or more nonoverlapping regions. For example, the MPU address space has the peripheral, FPGA slaves, SDRAM window, and boot regions.
The following figure shows the relationships between the HPS address spaces. The figure is not to scale.
The SDRAM window in the MPU address space can grow and shrink at the top and bottom (short, blue vertical arrows) at the expense of the FPGA slaves and boot regions. For specific details, refer to “MPU Address Space”.
