10.3. MPU Address Space

The HPS address space is 1 TB and is a superset of the MPU, L3NOC, peripherals, HPS2FPGA, LWHPS2FPGA, SDRAM registers, and SDRAM memory. The MPU address map covers the entire HPS address map, thus they are the same.

The MPU address space contains the following regions:
  • The boot region is located in the OCRAM.
  • The FPGA window (LWHPS2FPGA) in the MPU address map provides access to 512 MB of FPGA space.
  • The three FPGA windows (HPS2FPGA) in the MPU address map provide access to 256 GB of FPGA space.
  • The three SDRAM windows in the MPU address map provide access to 512 GB of SDRAM space.
  • The peripheral region contains 512 MB of address space. The peripheral region includes all slaves connected to the L3 interconnect, L4 buses, and MPU registers (SCU and L2), as well as the on-chip RAM (OCRAM).
