星载GPS接收机软件设计中的几个问题

Some Technologies of Spaceborne GPS Receiver Software Development

在GPS接收机软件设计中,文章针对堆栈使用问题提出了堆栈设置的理论和实用分析方法;针对资源共享问题,分析了资源同步与竞争的多种情况,提出了可靠同步、避免竞争的方法和措施;针对中断处理问题,分析并提出了中断处理的一般准则和中断嵌套与中断重入的应用条件和方法;最后对程序异常处理进行了分析并提出了解决措施。

Some technologies on GPS receiver software development are introduced in this paper and some useful suggestions are proposed： how to set stack depth properly, how to deal with synchronization ＆ competition, how to use nested interrupt and reentrant interrupt, and how to deal with exception.
