Abstract
The paper presents a real-time operating system (RTOS) that supports distributed shared memory (DSM) for distributed embedded control systems. The RTOS provides a location-transparent environment, in which distributed software modules can exchange input and output values through the DSM. The RTOS is an extension to OSEK OS and it utilizes a real-time network called FlexRay. The consistency of the DSM is maintained according to the order of data transfer through FlexRay, not using inter-node synchronization. The worst case response time of the DSM is predictable if the FlexRay communication is well configured.
