IP and Transceivers. PCIe. j_m_ch (Member) asked a question. December 17, 2019 at 4:20 PM. Minimum Latency of QDMA subsystem for PCIe. Hi all, What is the minimum latency for a 300-byte packet, for instance, using the QDMA subsystem for PCIe, from host to FPGA (VU9P)? There only seem to be measurements and documentation related to throughput ...
**BEST SOLUTION** Hi, This should be 16 or 32. We will update the document in the next revision. Thank you for pointing that out. Thanks.By Curt Wortman, Sr. Product Marketing Manager in Data Center Group Xilinx’s new streaming QDMA (Queue Direct Memory Access) shell platform, available on Alveo™ accelerator cards, provides developers with a low latency direct streaming connection between host and kernels. The QDMA shell includes a high-performance DMA …QDMA is wrapper of PCIe DMA. PG195 (v4.1) p.27 " For valid data cycles on the C2H AXI4-Stream interface, all data associated with a given packet must be contiguous.". Yes, s_axis_c2h_ctrl_len should be stable during transmission. s_axis_c2h_mty show empty bytes in the last beat when c2h_tlast set, at other time s_axis_c2h_mty=0.The Xilinx PCI Express Multi Queue DMA (QDMA) IP provides high-performance direct memory access (DMA) via PCI Express.

QDMA Ethernet Platform. The QEP design adds Ethernet support to QDMA based streaming platform. The Ethernet Subsystem is added to the static region of the shell. The platform has three physical functions, two physical functions for device management (PF0) and compute acceleration (PF1), and one physical function (PF2) for Network acceleration.
