In the full-power operation mode (shown as full power domain in the figure above), the entire system is up and running. Total power dissipation depends on the number of components that are running: their states and their frequencies. In this mode, dynamic power will likely dominate the total power dissipation.
To optimize static and dynamic power in full-power mode, all large modules have their own power islands to allow them to be shut down when they are not being used. To understand about full-power operation mode, see this link to the “Platform Management Unit” chapter in the Zynq UltraScale+ Device Technical Reference Manual (UG1085).
