Xdma ip, Apr 27, 2025 · The XDMA (Xilinx Direct Memory Access) driver provides Linux kernel support for Xilinx PCIe DMA IP cores. PCIe-XDMA (DMA Subsystem for PCIe) 是 Xilinx 提供给 FPGA 开发者的一种免费的、便于使用的 PCIe 通信 IP 核。 图1 是 PCIe-XDMA 应用的典型的系统框图， PCIe-XDMA IP核 的一端是 PCIe 接口，通过 FPGA 芯片的引脚连接到 Host-PC 的主板的 PCIe 插槽上；另一端是一个 AXI4-Master Port Product Description The AMD LogiCORE™ DMA for PCI Express® (PCIe®) implements a high performance, configurable Scatter Gather DMA for use with the PCI Express Integrated Block. The IP provides an optional AXI4-MM or AXI4-Stream user interface. This driver enables efficient data transfer between host system memory and FPGA hardware through the PCIe interface. Contribute to WangXuan95/Xilinx-FPGA-PCIe-XDMA-Tutorial development by creating an account on GitHub. The IP provides a choice between an AXI4 Memory Mapped or AXI4-Stream user interface. Aug 6, 2024 · 一、相关知识 当数据从上位机通过PCIe接口发送到端点设备，XDMA内部自行解包对将数据与指令进行分析，得到读写操作的指令地址，并对DDR进行读写操作。 操作的结果通过AXI接口返回XDMA，XDMA对数据进行组包，之后通过物理层发出，实现数据的DMA控制。 Oct 24, 2022 · DMA/Bridge Subsystem for PCI Express (XDMA IP/Driver) General Debug Checklist General FAQs XDMA Performance Debug Checklist Third-party references that may be helpful: Debug Gotchas Issues/Debug Tips/Questions Documents and Debug Collaterals Useful Links Mar 11, 2019 · This sample design has been set up to use a Gen3 x8 IP core, but other PCIe widths and speeds can be used. It still provides a customizable PCIe interface to the FPGA, but this IP also utilizes the DMA (Direct Memory Access) protocol.

The Xilinx PCI Express Multi Queue DMA (QDMA) IP provides high-performance direct memory access (DMA) via PCI Express. x Integrated Block. 1 and 3. Xilinx FPGA PCIe 保姆级教程 ——基于 PCIe XDMA IP核. The Xilinx® DMA/Bridge Subsystem for PCI Express® (PCIe®) implements a high performance, configurable Scater Gather DMA for use with the PCI Express® 2. A Gen1 x1 system can typically achieve 400 MB/s transfer rates that will not saturate the ICAP interface, but can still be used and will be much faster than the MCAP path. Xilinx’s user guide for this IP can be found here and Xilinx also provides an XDMA driver that can be used to interface with this IP over Windows 10 or Linux OS. The PCIe QDMA can be implemented in UltraScale+ devices. Xilinx XDMA IP Xilinx QDMA IP These samples are not generic—they match the exact structure of Xilinx’s DMA subsystem for PCIe: BAR mapping for control registers Descriptor setup Ring management Interrupt handling High-throughput user-mode DMA transfers For VCU118 users, this means you can: Build a standard Xilinx XDMA/QDMA design in Vivado 5 days ago · 文章浏览阅读1.
