The AMD DMA/Bridge Subsystem for PCI Express® ( PCIe® ) implements a high performance, configurable Scatter Gather DMA for use with the PCI Express® 2.1 and 3.x Integrated Block. The IP provides a choice between an AXI4 Memory Mapped or AXI4-Stream user interface.
This IP optionally also supports a PCIe AXI Bridge mode which is enabled for only AMD UltraScale+™ and AMD Spartan UltraScale+ devices. For details about PCIe AXI Bridge mode operation, see AXI Bridge for PCI Express Gen3 Subsystem Product Guide (PG194).
This document covers DMA mode operation only.
