Implementing and evaluation of an OSEK/VDX-compliant configurable real-time kernel

Abstract

As various applications become more and more sophisticated in automotive systems control units become more complex to meet specific requirements. This trend necessitates the use of an operating system to manage the complexity and to provide an abstraction for improving the portability of code. This paper presents a real time S kernel that is designed and implemented based on OSEK/VDX an open industry standard. Some features and optimizations of this kernel that make it appropriate for automotive applications among control unit nodes are also demonstrated. These optimizations include memory usage and a flexible framework of sporadic server for aperiodic nonblocking basic tasks scheduling. We evaluate these features by ensuing experiments and prove them to work efficiently.
