XDMA PCIe IP Compile the Reference Design Configure the Device via JTAG Configure the Device via Dual QSPI Connect to PCIe Host and Partially Reconfigure the FPGA Use Debug Cores to Monitor Activity Conclusion Supported Features Unsupported Features Known Limitations References Revision History Please Read: Important Legal Notices Figure 1. Then press " enter " to add IP to block design STEP TWO: Configuring XDMA PCIe IP At this point, XDMA IP is not configured, so it needs to be configured as per our requirements. 0 的SG 模式 DMA,提供用户可选择的 AXI4 接口或者 AXI4-Stream接口。 一般情况下配置成 AXI4 接口可以加入到系统总线互联,适用于大数据量异步传输,通常情况都会使用到 DDR,AXI4-Stream 接口适用于低延迟数据流传输。 XDMA 是SGDMA,并非Block DMA,SG 模式下,主机会把要传输的数据组成链表的形式,然后将链表首地址通过BAR 传送给XDMA,XDMA 会根据链表结构首地址依次完成链表所指定的传输任务。 1. . The Xilinx® LogiCORE™ DMA for PCI Express® (PCIe) implements a high performance, configurable Scatter Gather DMA for use with the PCI Express Integrated Block. This is M_AXI data-width, which will be connected to MIG-IP, which connects to DDR3 memory. In block design select " block automation ". It still provides a customizable PCIe interface to the FPGA, but this IP also utilizes the DMA (Direct Memory Access) protocol. nissan altima lug nut torque specs The design was implemented using the Block design feature of Vivado 2020.
