Transferring　Image　data　and　Video　data　will　expend　a　lot　of　bandwidth.　this　article　raise　an　AXI　DMA　high　speed　communication　interface　design　based　on　Zynq-7000.　Compared　with　traditional　DSP+FPGA　architecture,　the　new　Zynq7000　has　many　superiority.　such　as　low　cost,　low　power,　low　develop　difficulty,　software　and　hardware　re-custom.　User　can　create　a　new　IP　as　they　want.　this　method　decreases　the　number　of　digital　IC　and　devices.　This　system　use　AXI　DMA　interface　as　a　bridge　communicating　with　DDR3　SDRAM　and　FPGA.　On　the　basis　of　test,　the　speed　of　AXI　DMA　interface　can　reach　298MB/s.　it　can　absolutely　replace　traditional　Serial　RapidIO　and　EMIF(External　Memory　Interface)　in　DSP+FPGA　architecture.
