摘　　要：目前的嵌入式软件开发模式已无法满足嵌入式软件的快速发展,存在众多亟待解决的问题,一种可能的解决方案就是将容器技术应用于嵌入式领域,充分利用容器技术简部署、快启动、易迁移等优点。目前主流的容器主要是基于Linux系列操作系统创建的,依赖其提供的资源隔离与资源限制功能,但无法满足嵌入式平台的实时性与确定性要求。所以有必要研究面向嵌入式平台的资源控制组机制,使得嵌入式实时操作系统具有资源限制的功能,从而支撑容器的创建、运行与管理。详细分析了资源限制机制的研究现状,针对容器技术对操作系统资源限制的需求,根据嵌入式实时操作系统自有功能,自主设计并实现了嵌入式资源控制组机制的CPU与内存部分,针对现存问题提出了未来的研究方向。The current embedded software development model can no longer meet the rapid development of embedded software, and there are many problems that need to be solved urgently.One possible solution is to apply container technology to the embedded field and make full use of container technology to simplify deployment, quick start, easy to migrate and other advantages.At present, mainstream containers are mainly created based on the Linux series of operating systems, relying on the resource isolation and resource restriction functions provided by them, but this operating system cannot meet the real-time and deterministic requirements of embedded platforms.Therefore, it is necessary to study the resource control group mechanism for the embedded platform, so that the embedded real-time operating system has the function of resource restriction, so as to support the creation, operation and management of the container.This paper analyzes the current research status of resource restriction mechanism in detail.Aiming at the requirements of container technology for operating system resource restriction, according to the embedded real-time operating system′s own functions, the CPU and memory parts of the embedded resource control group mechanism are independently designed and implemented.Finally, in view of the existing problems, future research directions are proposed.
