摘要
为解决现有OSEK操作系统实时性不高、效率低等问题,提出了一种新的OSEK操作系统——MiniOSEK。MiniOSEK是建立在服务体/执行流模型的基础上,并符合OSEK/VDX标准规范的嵌入式操作系统。其设计思想是将消息驱动的思想引入到传统OSEK操作系统中,即当一个任务调用OSEK操作系统规范规定的应用程序编程接口(API)函数时,只需要向该接口函数发送一个消息。这样可以减少上下文切换所需的时间,提高嵌入式系统的实时性。
To solve the problems existing in the OSEK operating systems, such as low real-time performance and efficiency, this thesis proposes a new OSEK operating system, namely, MiniOSEK, which is built on the servent/exe-flow model, and in accordance with the OSEK/VDX standard. The design idea of MiniOSEK is introduce message-driven idea into OSEK operating system. When a task needs to call an API function which conform OSEK OS standard, it just needs to send a message to this API function. In this way, the time required for context switch can be shortened and the real-time of the embedded system can be improved.
