Abstract:In this paper,a design of PCI Express interface card based on NiosⅡ is presented.The composition theory of NiosⅡsoft-core processor and the process of LVDS signal processing and application PCIE bus communication are introduced.Each functional module and the specific of the design principium are given a detailed discussion.Functional realization of the system was tested one by one,the test results show that the stable interface card can complete the data transfer effectively.
Keywords:LVDS NiosⅡ Deserializer High-speed communications PCI-Express
