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...

A common approach is to build systems that combine AXI4-Stream and AXI memory-mapped IP together. Often a DMA engine can be used to move streams in and out of memory. 注意AXI Data width converter 和 AXI Direct Memory Access支持的AXI接口协议。 8.AXI SmartConnect IP and AXI Interconnect IP...
上文提到AXI4 和 AXI4-Lite采用了memory-mapped的方式,无论是1个master和1个slave、1个master和N个slave、N个master和1个slave、N个master和M个slave,采用这两个ip能帮助我们完成映射。 AXI FIFOs: 缓存数据,或者跨时钟域时有用。 AXI Direct Memory Access (DMA) engines ...

AXI Direct Memory Access (DMA) engines 当我们有一个AXI4-stream接口的IP想与AXI4接口的IP相连时,可以通过AXI DMA完成转换。 ZYNQ上的AXI接口 图片源自 zynq 7 processing system ip zynq的ps上共留了9个AXI接口,其中两个GP AXI master、两个GP AXI slave、四个HP AXI slave、以及一个ACP AXI slave。
This is the driver for the AXI Video Direct Memory Access (AXI VDMA) core, which is a soft Xilinx IP core that provides high- bandwidth direct memory access between memory and AXI4-Stream type video target peripherals. The core provides efficient two dimensional DMA operations with independent ...
1. 打开Vivado模板工程,在Block Design中点击"Add IP",搜索AXI Direct Memory Access模块,双击添加到工程中。 2. 连接AXI总线。点击"Run Connection Automation",点击"OK",vivado会自动将AXI DMA连接到ZYNQ PS端,连接后如下图所示。 3. 现在,我们要连接AXI DMA控制器的M_AXI_SG, M_AXI_MM2S和M_AXI_S2MM...
…ess Engine This patch adds support for the AXI Central Direct Memory Access (AXI CDMA) core to the existing vdma driver, AXI CDMA is a soft Xilinx IP core that provides high-bandwidth Direct Memory Access(DMA) between a memory-mapped source address and a memory-mapped destination address....
