3.qdma; 4.xpdma; 5.fdma; 6.udma. 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;...
(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相当于上图中的PCIe core+TLP处理。 (3)dma/bridge subsystem for pci express(pcie):就是xdma,它不但处理了TLP,而且DMA也一起包含在IP中,相当于上图中的...
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/...
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模式下影响不大。
the SmartConnect is more tightly integrated into the Vivado design environment to automatically configure and adapt to connected AXI master and slave IP with minimal user intervention. The AXI Interconnect can be used in all memory-mapped designs. There are certain cases for high bandwidth application...

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...
DMA/Bridge Subsystem for PCI Express in AXI Bridge mode supports UltraScale+ Integrated Blocks for PCI Express Maximum Payload Size (MPS) up to 256 Bytes Multiple Vector Messaged Signaled Interrupts (MSIs) Memory mapped AXI4 access to PCIe space DMA/Bridge Subsystem for PCIe in AXI Bridge mode...
I'm working on a project that uses the AXI Bridge for PCI Express Gen2 Subsystem targeted for the nitefury(artix7) board and I have a question about AXI Memory Mapped for PCI Express Address Mapping. How can I configure the AXI to PCIe translation parameter when I build the system in ...
The function of the AXI Memory Mapped to Stream Mapper IP (axi_mm2s_mapper) is to encode and decode AXI4 Memory-Mapped (AXI4-MM) transactions into AXI4-Stream (AXI4-S) transfers. 查看所有版本 PG156 - UltraScale Devices Gen3 Integrated Block for PCI Express LogiCORE IP Product Guide (...
