The platform management controller (PMC) subsystem includes the following functions:

  • Boot and configuration management
  • Dynamic Function eXchange (DFX)
  • Power management
  • Reliability and safety functions
  • Life-cycle management, including device integrity, debug, and system monitoring
  • I/O peripherals

The PMC block executes the BootROM and platform loader and manager (PLM) to handle the boot and configuration for the processing system, CPM, PL, NoC register initialization and settings, and I/O and interrupt configuration settings. In addition to boot and configuration, the PLM provides life-cycle management services. The PMC bus architecture and centralized integration enables significantly faster configuration and readback performance when compared with previous devices. The following table shows the Zynq UltraScale+ MPSoC blocks that are comparable to the Versal adaptive SoC blocks.
