PCI　Express　is　rapidly　establishing　itself　as　the　successor　to　PCI,　which　provides　higher　performance,　increased　flexibility,　and　scalability　for　next-generation　systems.　FPGA　offers　a　flexible　solution　for　PCI　Express　compared　with　ASIC.　Using　IP　Core　and　designing　a　DMA　module　in　FPGA,　this　paper　implemented　a　high-performance　PCI　Express　system.　IP　Core　handles　the　protocols　defined　by　PCI　Express　specification.　DMA　module　accelerates　the　transmission　between　FPGA　and　PC　memory,　sufficiently　exploiting　PCI　Express　bus　bandwidth.　This　article　proposes　and　achieves　a　PCI　Express　system　having　DMA　transfer　ability　and　emphatically　describes　the　design　of　the　DMA　engine　in　system-logic,　in　addition　to　the　corresponding　Windows　WDM　driver　and　GUI　application.　The　result　of　performance　test　is　presented　finally.　©2009　IEEE.
