摘要
自由软件运动和Linux的兴起,给嵌入式系统的设计带来全新的设计思想,即可以根据应用定制实时内核。本文利用软件工程中的数据流图工具,给出了嵌入式Linux平台上的GPS/INS组合导航系统的软件逻辑模型:4个独立的任务和3个设备驱动程序,该逻辑模型清晰、完整,然后给出了组合导航系统软件的设计,为编码提供依据。
Free software and Linux have caused a revolution in embedded system,and bring the novel realization to embedded system desig n.The real time core may be tailored to application.According to data flow dia-g ram,GPS /INS coupling navig ation system log ical model based on embedded Linux is composed of four processes and three device drivers,which are clearly expressed.Then the system desig n is provided which is helpful for coding .
