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 integrated block for pcie:这个就是一个PCIE IP CORE,需要开发者自己组织好memory read和 memory write类型的报文和PCIE core进行交互; 2.axi-memory mapped to pcie:这个IP适合对TLP层不太熟悉的使用,这个IP对用户屏蔽了TLP协议的处理,通过 AXI接口和IP交互数据,这个IP相当于PCIE_IP_CORE + TLP包...
(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...
When an AXI Memory Mapped to PCI Express core is configured withC_S_AXI_ID_WIDTH = 13or higher, synthesis will fail with the following error message: ERROR:HDLCompiler:1318 - "D:/Xilinx/14.6/ISE_DS/EDK/hw/XilinxProcessorIPLib/pcores/axi_pcie_v1_08_a/hdl/vhdl/axi_slave_read.vhd" ...
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/...
Previously when I had this same problem the issue was with the PCIe connection with the host. Although it appeared correctly and I could see the BAR mapped, whenever I tried to read any address I was only getting 0xFFFFFFFF. After rebooting the host, the address mapping of the PCIe change...
Hello,In my basic understanding of PCIe, the PCIe Endpoint device is telling the Root Complex (or the processing system) which memory ranges/size it is requesting (BAR Configuration).Is the "AXI Memory Mapped to PCI Expre
Stream模式下影响很明显,在AXI Stream模式下选择多通道,可以连接不同的数据源。在AXI Memory Mapped...
