一种适用于嵌入式平台的任务加载框架

设计了一种适用于嵌入式平台的应用任务动态加载框架,该框架适用于大部分嵌入式操作系统。通过设计适合于嵌入式系统的可执行目标文件格式、任务加载器、内核系统调用,从而使嵌入式系统可以动态加载存储器内的任务执行。测试结果表明,可以在不影响任务执行效率的情况下,增强嵌入式系统的灵活性。

This paper designs a common framework which can be applicable to dynamic loading applications in embed- ded platform.it can be applicable to most of embedded operation systems.Based on the design of an executable file for- mat,a task loader and a system call for OS,kernel can dynamic loading an embedded task from External memory.
