1.1. Stratix V Avalon-ST Interface for PCIe Datasheet
Intel ® Stratix® V FPGAs include a configurable, hardened protocol stack for PCI Express® that is compliant with PCI Express Base Specification 2.1 or 3.0. The Hard IP for PCI Express using the Avalon Streaming (Avalon-ST) interface is the most flexible variant. However, this variant requires a thorough understanding of the PCIe® Protocol.
Refer to the AN 456: PCI Express High Performance Reference Design for more information about calculating bandwidth for the hard IP implementation of PCI Express in many Intel FPGAs, including the Intel® Arria® 10 Hard IP for PCI Express IP core.
