The core supports these power management modes:

  • Active State Power Management (ASPM)
  • Programmed Power Management (PPM)

Implementing these power management functions as part of the PCI Express design enables the PCI Express® hierarchy to seamlessly exchange power-management messages to save system power. All power management message identification functions are implemented. The subsections in this section describe the user logic definition to support the power management modes.

For additional information on ASPM and PPM implementation, see the PCI Express Base Specification.
