The AMD QDMA Subsystem for PCI Express ( PCIe® ) implements a high performance DMA for use with the PCI Express® Integrated Block with the concept of multiple queues that is different from the DMA/Bridge Subsystem for PCI Express which uses multiple AMD Card to Host (C2H) and Host to Card (H2C) channels.
This guide covers the QDMA Subsystem for PCIe® for AMD UltraScale+™ devices.
Important: In this guide, AMD UltraScale+™
refers to both the existing UltraScale+ and the new Spartan UltraScale+ devices.
