VDMA 用于将 AXI Stream 格式的数据流转换为 Memory Map 格式或将 Memory Map 格式的数据转换为 AXI Stream 数据流, 也就是说 VDMA 内核旨在提供从 AXI4 域到 AXI4-Stream 域的视频读/写传输功能,反之亦然,从而实现系统内存(主要指DDR3) 和基于 AXI4-Stream 的目标视频 IP 之间的高速数据移动。VDMA 的框...
Hello, I would like an IP that I can program a start address from an SoC's CPU address space and a length, and the IP will read the memory via
Digital Blocks DB-AXI4-MM-TO-AXI4-STREAM-BRIDGE Verilog RTL IP Core accepts AXI4 Memory Map address, control, and data input, converts the address to ...

对于视频数据传输,AXI4-Stream端口可以配置从8位到1024位宽(8的倍数)。对于AXI4- stream端口比相关的AXI4内存映射端口窄的配置,AXI VDMA会在内存映射端升级或缩小提供全总线宽度突发的数据。它还支持异步操作模式,其中所有时钟都是异步处理的。 VDMA 用于将 AXI Stream 格式的数据流转换为 Memory Map 格式或将 Mem...
Hello, I would like an IP that I can program a start address from an SoC's CPU address space and a length, and the IP will read the memory via AXI-4 and generate AXI4-Stream data transactions as it is allowed by downstream tready. Xilinx has an AXI-DMA IP for thi...
