基于PCI-Express的高速数据交换设计及应用:
摘要:
提出了利用PCIE总线技术实现数据高速传输的方案，结合共享内存、DMA等技术设计了基于PCI鄄Express总线的高速数据传输卡,实现了将采集的数据实时传送到PC的共享内存缓冲区，数据传输采用DMA方式。采用接口器件PEX8111实现PCI鄄Express总线到PCI总线的桥接。使用FPGA编写PCI总线的接口逻辑，最后进行测试。
Abstract:
Abstract:Hardware design and implementation of high speed data transfer based on PCI-Express bus is proposed High speed data transfer card based on PCI-Express bus is designed combining shared memory,DMA technique.PCI-Express card is realized transfer data collected to the shared buffer in the PC’s memory in real time and data transfer mode is DMA.The system design implements bridge interface from PCI-Express bus to PCI bus with.interface chip PEX8111,compiles interface logic of PCI bus with FPGA.In the end,The test is explained.
