基于PCI-Express的高速數(shù)據(jù)交換設計及應用:
摘要:
提出了利用PCIE總線技術實現(xiàn)數(shù)據(jù)高速傳輸?shù)姆桨?，結合共享內(nèi)存、DMA等技術設計了基于PCI鄄Express總線的高速數(shù)據(jù)傳輸卡,實現(xiàn)了將采集的數(shù)據(jù)實時傳送到PC的共享內(nèi)存緩沖區(qū)，數(shù)據(jù)傳輸采用DMA方式。采用接口器件PEX8111實現(xiàn)PCI鄄Express總線到PCI總線的橋接。使用FPGA編寫PCI總線的接口邏輯，最后進行測試。
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.
