Honored Contributor:)i just load a image into ssram(de2-70 board through panel-tool) , i want get datas out ,then i think of dma ,meantime i saw a paper in the internet,it uses this mather throug dma do the same thing and also shows a module image without source code (those in/outputs are belowe ) . but in the paper it seems the dma module is writed by hand and made by fifo megawizard ,so i wonder if i can make one by sopc builder , aha...:), just a weird idea .
