MiniOSEK Operating System Based on Servent/exe-Flow Model

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.
