Design of PCI Bus Intelligent GJB289A Simulator

在某虚拟仿真实验平台系统中,需要收发批量GJB289A总线数据,并且按不同算法对数据进行实时处理。为此,设计了PCI总线智能GJB289A仿真卡。采用FPGA实现GJB289A接口逻辑,设计了GJB289A总线模拟收发器,替换了国外芯片,降低了系统成本。采用DSP的PCI接口在线加载程序的方式,在线更新数据处理算法,并按照相应算法对GJB289A总线数据进行快速处理,提高了仿真系统的灵活性和实时性。目前,该仿真卡在虚拟仿真实验平台系统中成功使用,工作稳定。

Since an certain virtual simulation platform needs to transmit and receive numerous GJB289A data and has to perform data, real-time processing according to the different algorithms, the PCI bus intelligent GJB289A simulator was designed. The high-speed DSP is adoted to process the received Gj＇B289A data and the real-time of the system is improved. The host loads the DSP programme through the PCI bus, updates the data processing algorithms and increases the flexibility of the system. FPGA is employed to achieve GJB289A interface logic. GJB289A bus analog transceiver is designed to replace the foreign chips and lower the system cost. At present the card is successfully used in the simulation platform of a virtual simula- tion system, and it works stable.
