摘要
为了使基于硬件架构的卫星导航信号模拟器满足实时数据的传输要求,采用一种高速的数据通信技术SRIO,实现DSP与FPGA芯片间的互连数据传输。文章给出了SRIO接口的整体方案设计,确定了适合项目所需要的数据传输的格式类型与事务类型,对各端接口代码进行联机调试并结合数据乒乓操作方式对比分析数据传输的可靠性。最后成功实现了SRIO接口在DSP与FPGA间的数据传输,保证了各端数据处理的独立性与交互的便捷性,并将该技术方案应用于卫星导航信号模拟器的开发中。
To satisfy the real-time data transmission requirements,the satellite signal simulator based on hardware architecture uses a high speed data communication technology of SRIO to realize interconnection structure between DSP and FPGA processor.The paper presents an overall design scheme of SRIO interface and determines the format type and transaction type of data transmission for the project needs through software simulation test.After on-line debugging of the interface code of each modules and the data ping-pong operation,the reliability of data transmission are analyzed by softwares.Finally,the interconnection of SRIO interface between DSP and FPGA is successfully realized,which guaranteed the independence of data processing and convenience of interaction between hardware modules,and this technical scheme is applied to the satellite signal simulator system development.
