资料介绍

Getting started with direct memory access on Xilinx boards may be initially


overwhelming.First of all Xilinx distinguishes AXI DMA and AXI VDMA in


programmable fabric.AXI DMA refers to traditional FPGA direct memory access


which roughly corresponds to transferring arbitrary streams of bytes from FPGA to a


slice of DDR memory and vice versa.VDMA refers to video DMA which adds


mechanisms to handle frame synchronization using ring buffer in DDR,on-the-fly


video resolution changes,cropping and zooming.
