The AXI Memory Mapped to PCIe® Gen2 IP core provides an interface between the AXI4 interface and the Gen2 PCI Express® (PCIe) silicon hard core. The AXI4 PCIe provides full bridge functionality between the AXI4 architecture and the PCIe network. The IP is composed of the PCIe core,...
@文心快码BaiduComateaxi memory mapped to pci express 文心快码BaiduComate AXI内存映射到PCI Express 1. AXI内存映射的概念 AXI(Advanced eXtensible Interface)是一种高性能、高带宽、低延迟的片内总线协议,广泛应用于SoC(System on Chip)设计中,用于连接CPU、DSP、FPGA等处理单元与各种内存和外设。AXI内存映射指...
AXI4-Stream与 Memory-Mapped协议的结合: 一种常见的方法是构建将 AXI4-Stream 和 AXI内存映射 IP组合在一起的系统。通常可以使用AXI Direct Memory Access (DMA) engines将Stream移进或移出内存。 例如,处理器可以使用DMA引擎解码数据包或在流数据之上实现协议栈,以构建更复杂的系统,其中数据在不同的应用程序空间...
