Xilinx Answer 65444

Xilinx PCI Express Windows DMA Drivers and Software Guide

The Xilinx PCI Express DMA IP provides high-performance direct memory access (DMA) via PCI Express. The PCIe DMA

can be implemented in Xilinx 7 Series XT and UltraScale devices. This answer record provide drivers and software that can

be run on a PCI Express root port host PC to interact with the DMA endpoint IP via PCI Express. The drivers and software

provided with this answer record are designed for Windows 7 operating systems and can be used for lab testing or as a

reference for driver and software development. Through the use of the PCIe DMA IP and the associated drivers and software

you will be able to generate high-throughput PCIe memory transactions between a host PC and a Xilinx FPGA.

PCIe DMA Driver for Windows Operating Systems

The following operating system is supported:

- Windows 7 Enterprise 64-bit

3. Open the Device Manager (Control Panel -> System-> Device Manager)

4. Initially, the device will be displayed as a PCI Memory Controller device.

5. Right-Click on the device and select Update Driver Software and select the folder of the built XDMA driver

6. If prompted about unverified driver publisher, select ‘Install this driver software anyway’ (see note below).
