As　a　common　high-speed　interface,　PCIe　interface　is　very　extensive　in　the　field　of　data　acquisition([1]).　As　a　development　framework　of　Microsoft,　WDF　(Windows　Driver　Foundation)　driver　model　can　reduce　the　difficulty　of　the　development.　Based　on　the　PCIe　high-speed　image　acquisition　card　which　is　developed　by　ourselves,　this　paper　designed　a　stable　and　reliable　WDF　driver　for　the　high　data　transmission　rate　in　the　image　acquisition　process,　and　used　the　memory　allocation　method　in　WDF　to　share　buffer　with　the　application.　In　order　to　enhance　the　speed　of　the　image　acquisition,　this　paper　designed　a　ring　buffer　mechanism　to　ensure　the　continuity　and　stability　in　the　image　acquisition　and　transmission　process.
