The majority of automotive companies have evaluated the overhead associated with automatic code generation (as compared to manual coding), and many have found it to be within acceptable production limits, and in some cases the automatic generated code can be more efficient than manual code. They now want to harness this capability directly with the OSEK Operating System. This paper describes the use of an OSEK/VDX Real-Time Operating System (RTOS) and an open, integrated development tools platform to allow a development downflow for high-level Computer Aided Software Engineering (CASE) design entry and simulation/validation, rapid prototyping down to the target hardware for calibration and debugging and the up-flow by feeding the data collected from the target Electronic Control Unit (ECU) for system analysis and debugging all the way back to the entry CASE level.

This paper describes the use of an OSEK/VDX Real-Time Operating System (RTOS) and the implementation of an OSEK compliant communication protocol, layered on the CAN Bus or the SAE J1850 standard, that supports a distributed framework. The paper provides an overview of the OSEK/VDX specification and examines the application programming interface (API) and the code generation software necessary to configure and implement a distributed control system. The paper will use a simple illustration to demonstrate the implementation process, providing example OIL and C files.

This paper describes the first single-core 32-bit microcontroller-DSP architecture, TriCore, optimized for real-time embedded systems, an OSEK/VDX Real-Time Operating System (RTOS) and an open, integrated development tools platform to allow a development downflow for high-level Computer Aided Software Engineering (CASE) design entry and simulation/validation, rapid prototyping down to the target hardware for calibration and debugging and the up-flow by feeding the data collected from the target Electronic Control Unit (ECU) for system analysis and debugging all the way back to the entry CASE level. Also described are the different features of the new 32-Bit microcontroller-DSP, which speeds up the execution of embedded control applications and simultaneously reduce memory demand.

This project is on-going at present and further detailed technical results will be included in the presentation at the Congress.
