摘　　要：针对实时操作系统复杂性内核导致嵌入式应用程序编译速度慢、可复用性差的问题,提出基于通用嵌入式计算机架构(GEC)的RT-Thread实时操作系统驻留方法。在合理划分存储空间的基础上,通过对中断服务例程进行共享,为用户提供底层驱动与软件应用层的函数调用服务。最后以D1-H应用处理器为例进行RT-Thread驻留测试。实践结果表明,该驻留方法实现了系统内核与应用程序的物理隔离,编译时间更短,开发效率更高,为嵌入式程序开发的时效性、便捷性和简易性提供了应用基础。This paper proposed a method for the residency of the RT-Thread real-time operating system based on the general embedded computer(GEC)architecture to address the issues of slow compilation speed and poor reusability caused by the complexity of the real-time operating system kernel in embedded applications.On the basis of reasonable storage space allocation,the method achieved the sharing of interrupt service routines,providing users with function call services for both low-level drivers and software application layers.Finally,the residency method was tested using the D1-H application processor as an example.And the results demonstrate that it achieves physical isolation between the system kernel and application programs,resulting in shorter compilation time and higher development efficiency.This method provides a foundation for the timeliness,convenience,and simplicity of embedded program development.
