摘要
针对工程实践对导航计算机实时高精度解算的需求,设计一种基于FPGA和DSP架构的嵌入式导航计算机,FPGA作为核心控制器,完成数据采集整合、系统时序控制、导航参数存储与上传等功能,DSP作为协同处理器,完成导航参数的实时高精度解算和数据回传功能;详述系统硬件结构设计、主要时序逻辑控制以及姿态解算算法,并通过跑车实验对系统工作性能进行测试;实验表明该系统能够实时的高精度解算载体姿态参数;系统体积小、功耗低、灵活性好。
Meeting the demands of real--time and high precision calculation of the navigation computer in engineering, a navigation corn puter baaed on FPGA and DSP has designed. FPGA , as the core controller in the system, completed functions o; data acquisition and inte gration, system timing logic control, store and upload navigation data. DSP, as a coprocessor, calculated navigation parameters and send it back to FPGA. The paper was introduced system hardware architecture, main timing logic control method and attitude calculation algorithm. Test the system performance by car experiment, the experiment results show that the embedded navigation computer could real--time and high precision calculate attitude parameters of the car. The system is small size, low power consumption and good flexibility.
