摘要
嵌入式应用场景非常广泛,分为多种应用模式,分别需要不同特征、架构的嵌入式操作系统。分析了主流的嵌入式实时操作系统,根据应用模式与技术特征将操作系统抽象为轻量操作系统、实时多任务操作系统、分区操作系统、多级安全操作系统等不同种类,并从技术特征、能力组成、结构框架等角度对操作系统的软件架构进行描述,提出一种统一的、开放的、弹性的操作系统软件架构,支持单一操作系统通过配置方式同时满足多种应用模式的需求。
Embedded application scenarios are very extensive,divided into a variety of application modes,respectively need different characteristics,architecture of the embedded operating system.Firstly,the mainstream embedded real-time operating system is analyzed,and the operating system is abstracted into lightweight operating systems,real-time multi-task operating systems,partitioned operating systems,multi-level security operating systems and so on according to the application mode and technical characteristics.The operating systems is formed in terms of technical characteristics,capability composition,structure framework and so on.The software architecture is described.Finally,a unified,open,flexible operating system software architecture is proposed to support a single operating system to meet the needs of multiple application modes through configuration.
