摘　　要：数字通信相关技术以及计算机技术的快速发展极大地推动了高速数据传输的需求,PCIe Gen5信号速率已经达到32 Gb/s,在数据采集、雷达通信、遥感探测等领域,数据量的日益增大和数据处理的日益复杂化,使高速数据传输逐渐成为通信系统设计中的关键点。Xilinx提供的DMA/Bridge Subsystem for PCI Express IP是一个高性能,可配置的,适用于PCIe 2.0、PCIe 3.0的SG模式DMA,该文主要介绍了XDMA的配置说明、数据通路搭建及相关测试性能,实测结果与PCIe相关测试速率比较。The rapid development of digital communication-related technology and computer technology has greatly promoted the demand for high-speed data transmission. PCIe Gen5 signal rates have reached 32 Gb/s. In the fields of data collection, radar communications and remote sensing detection, the increasing volume of data and the growing complexity of data processing have made high-speed data transmission become a key point in the design of communication systems. The DMA/Bridge Subsystem for PCI Express IP provided by Xilinx is a highperformance, configurable SG-mode DMA suitable for PCIe 2.0 and PCIe 3.0. This article mainly introduces the configuration instructions, data path construction and related test performance of XDMA, and compares the measured results with PCIe related test rates.
