1.5. Configurations

The Avalon-MM Intel® Arria® 10 Hard IP for PCI Express includes a full hard IP implementation of the PCI Express stack comprising the following layers:

  • Physical (PHY), including:
    • Physical Media Attachment (PMA)
    • Physical Coding Sublayer (PCS)
  • Media Access Control (MAC)
  • Data Link Layer (DL)
  • Transaction Layer (TL)

When configured as an Endpoint, the Arria® V GZ Hard IP for PCI Express using the Avalon-MM supports memory read and write requests and completions with or without data.
