考虑到资源和对DMA的特定需求,笔者最近使用了第二个IP:axi memory mapped to pci express。 接口 该IP的接口数量比较多,但是相对比较简单,如下图所示: axi接口主要是axi_master和axi_slave接口,实现host到FPGA和FPGA到host的读写操作;axi_lite接口是该IP内部寄存器的读写的接口;中断接口是发起msi中断的接口,时钟...
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。

(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...
