36.3 System Resource: Memory Layout
Figure 36-2.
• The upper 16Kbytes PCIe host configuration space.
• This memory segment is used to map the configuration space of PCIe RC. SW
can access PCIe RC core configuration space through the DBI interface.
• PCIe device configuration space.
• Used to map the configuration spaces of PCIe EP devices that are inserted to the
RC downstream port.
