Software architectures for OSEK/VDX applications using MATRIXX TM and AutoCodeTM

This paper describes the convergence of automatic code generation from graphical diagrams and real-time operating system (RTOS) technology. In the field of automatic code generation the concept of configurable code generators which allow the user to make compromises between speed and program size as well as the format and style of the code have allowed this technology to branch out of its more traditional rapid-protyping and desktop simulation strongholds. In the area of operating systems, the relatively recent launch of the OSEK specification has provided the foundation for automotive manufacturers and suppliers to make use of commercially available operating systems for their applications. This paper presents several techniques which allow a configurable C code generator, such as AutoCode, to efficiently use the utilities provided by an OSEK compliant RTOS to develop portable and reusable software for automotive electronic control units
