The platform processing unit (PPU) normally runs the platform loader and manager (PLM) firmware. The PLM configures the system, downloads boot image files, monitors the system, and provides platform services. The resources available to the PPU firmware include security, power control, error detection, and functional safety features.

The PPU implements the MicroBlazeâ„¢ architecture. It is a host on the PMC main switch and issues TrustZone-secure transactions.
