基于PCIE的SG DMA高速数据传输系统
High Speed SG DMA Data Transmission System Based on PCIE
摘要
Abstract
Combined with the specific application for high-speed data encryption card,introduce PCI Express bus protocol,the structure of the high-speed data transmission system based on PCI Express and hardware circuit of FPGA as the core. The method of using WinDriver to generate PCIE device driver software and realize high speed data transferring with SG DMA under Windows XP operation system is al-so discussed. The program has already been debugged and DMA data transmission is successful between the computer and the Arria II GX development board. The system uses PCIE IP hard core instead of a dedicated interface chip to realize the PCI Express bus interface logic, greatly improving the flexibility of the design,and the use of SG DMA method can meet the requirement of high speed data transmission.关键词
