| Abstract: | OSEKTime specification proposes the coexistent model based on the time triggered operation system and the operation system realized by OSEK/VDX standard. Based on the analysis of OSEKTime specification, a reasonable and improved operation system based on real time triggered was presented to overcome the limitations in its message triggered task and the problem of coexistence between OSEKTime OS and the OSEK/VDX standard. The experiment indicates that it guarantees time triggered task real time and processes the message triggered task in deadtime. |
