基于高性能DSP的GPS导航解算模块设计与实现

摘要

Based on the TMS320C6747 digital signal processor, with its excellent performance of floating point calculation, this paper puts forward a new satellite navigation solution module.Based on the hardware, its not only give the hardware design method, but also achieving the DSP and FPGA in less interface of the high speed data transfer conditions. In software, the navigation the solution to the existing algorithm make improvement, optimize the code, increase code execution ef~ciency. The final test results show that the scheme design according to the navigation out the solution module is low power consumption, software is easy to escalate, fast and friendly man-machine interface characteristics. For the development of a new generation of navigation decoding module provides a new design%本文基于TMS320C6747数字信号处理器，凭借其优异的浮点运算性能，提出了一种新型卫星导航解算模块的设计方法。在硬件方面，不仅给出了硬件设计方法，还实现了DSP与FPGA在较少接口条件下的高速数据传输。在软件方面，在现有的导航解算算法的基础之上做出改进，进一步优化代码，提升代码执行效率。最后的测试结果表明根据本方案设计出来的导航解算模块具有低功耗、软件易升级、运行速度快以及友好的人机交互界面等特性，为发展新一代导航解算模块提供了一条新的设计方案。
