The PMC/PS interconnect transactions include a 44- or 49-bit address:

  • 44-bit physical address (32 TB)
  • 48-bit virtual address (512 TB) plus a context selection bit

When routing a transaction to the FPD SMMU, use a 48-bit address with a 49th bit used to define the operating contect: application or kernel. All other destinations, including memories, NoC, and PL, use 44-bit addressing. The routing controls for each source are listed in Routing and Coherency Controls section.
