QDMA subsystem. It includes the Xilinx QDMA IP and RTL logic that bridges the QDMA IP interface and the 250MHz user logic box. The interfaces between QDMA subsystem and the 250MHz box use a variant of the AXI4-stream protocol. Let us refer the variant as the 250MHz AXI4-stream. U45N has two QDMA subsystems.
