The Zynq UltraScale+ MPSoC power management framework (PMF) is based on an implementation of EEMI, see the Embedded Energy Management Interface EEMI API Reference Guide (UG1200). It includes APIs that consist of functions available to the processor units (PUs) to send messages to the power management controller, as well as callback functions in for the power management controller to send messages to the PUs. The APIs can be grouped into the following functional categories:

  • Suspending and waking up PUs
  • Slave device power management, such as memories and peripherals
  • Miscellaneous
  • Direct-access
