As the architecture of automotive software is complicated and LOC of software increases, there is an increasing demand for standard operating system. OSEK/VDX defines an industry standard for automotive operating system and middleware. This paper introduces an implementation of RTOS(OSCAR-OSEK) based on OSEK/VDX standard. For better speed of scheduling, we suggest a new method for ready queue implementation considering the characteristic of automotive application software. Also we introduce a method for improving the portability of RTOS on various MCUs. And, we show OSCAR-OSEK implementation and performance test results.
