摘　　要：为了满足低成本组合导航系统的需要,设计了利用DSP技术和FPGA技术的导航计算机,文中以数字信号处理器浮点DSP TMS320VC33为主处理器,FPGA实现里程仪信号的计数和与数据通信芯片TL16C554结合扩展DSP外部串口的功能,整个系统具有体积小、成本低、功耗低和实时性好的优点。In order to meet the requirement of low cost navigation system, a navigation computer based on DSP and FPGA technologies is designed. In this paper, the floating point DSP TMS320VC33 is taken as the principal processor, FPGA implements the count of odometer and is combined with data communication chip TL16C554 to expand the capability of DSP external serial part. The whole system has the advantages of small volume, cost-effectiveness, low power dissipation and good real-time performance.
