摘要
针对海底地形匹配辅助导航系统中需要多路数据同步接收、匹配结果实时回传的特点,设计了基于DSP和FPGA的多通道实时地形匹配辅助导航系统。该系统通过高性能通用DSP芯片实现实时海底地形匹配算法,通过基于FP-GA的SOPC技术实现多通道数据通信接口和数据流控制,具有电路结构简单、对外接口灵活、功能易于扩展、系统结构可重配置的优点。软件仿真和现场试验结果表明,该系统能够良好的满足水下潜器对于海底地形匹配导航系统的实时性、稳定性、扩展性和体积功耗等方面的要求,具有良好的工程应用前景。
According to the demands of synchronization receive of multiple data and real-time return of match result in the terrain matching assistant navigation system,a terrain matching system based on DSP and FPGA was designed and implemented.The real-time underwater terrain matching algorithm was realized by high-performance float DSP chip TMS320C6713.The multi-channel data communication interface and data flow control was accomplished through SOPC technology based on FPGA,with valuable merit of simple circuit structure,flexible external interface,and easy reconfiguration.Simulation and field test results show that the system could well meet the requirements of the underwater vehicle with high real-time performance,high stability,flexible scalability,and low power consumption,which make it has good application prospect in engineer.
