Dynamic Function eXchange (DFX) configuration enables one or more sub-regions of the device to be independently reprogrammed with new configuration data while all remaining regions (static or reconfigurable) remain active and unaffected. The DFX PDI can come either from PCIe, DDR memory, or the primary boot device. For loading the DFX PDIs, the XilLoader CDO commands can be used using the IPI interface. XilFPGA provides the required APIs to load DFx PDIs from Cortex-A72 or Cortex-R5F.
