AXI Memory Mapped to PCIe® Gen2 IP 核提供了 AXI4 接口与 Gen 2 PCI Express (PCIe) 芯片硬核之间的接口。 AXI4 PCIe 可提供 AXI4 架构和 PCIe 网络之间完整的桥接功能。 IP 由 PCIe 核、GT 接口和 AXI4 接口构成。 桥电路在 FPGA 架构中实现,PCIe 核和 GT 是 FPGA 中的硬核元素。
AXI内存映射到PCI Express通常不是直接进行的,因为AXI是片内总线协议,而PCIe是片间或系统间的总线协议。但是,在嵌入式系统或高性能计算平台中,可能会通过FPGA等可编程逻辑器件来桥接这两种总线。 FPGA可以设计实现一个AXI到PCIe的桥接逻辑,该逻辑负责将AXI总线的内存映射地址空间转换为PCIe总线的地址空间,并处理两种总线...
(1)7 series intergrated block for pci express:这个IP就相当于上图中的PCIe core,用户要组织好memory read和memory write类型的报文和PCIe core进行交互。 (2)axi memory mapped to pci express:如果对于TLP层的处理不太熟悉的话,那这个IP就比较合适了,它屏蔽了TLP协议的处理,通过AXI接口和IP交互数据,这个IP相...
反正,目前各个厂家设计的pcie dma,都自己名一个名称。 AXI MEMORY Mapped to pci express 1.IP核屏蔽了TLP协议的处理细节,使得用户无需深入了解TLP协议即可轻松完成; 2.axi_master和axi_slave接口主要实现host to fpga以及fpga to host的读写操作;
Alternatively, you can use the MYVIVADO environment variable and point this to the location of the patch. After the patch is installed, the version of the AXI Memory Mapped to PCI Express core should indicate: v2.7 (Rev. 66348). Note: "Version Found" refers to the version where the probl...
达到的速度已经很客观了，由于AXI Memory Mapped to PCI Express的IP核配置中，PCIe x8只能做到2.5GT/...
