A real-time operating system with location-transparent inter-core and inter-node system calls for distributed embedded control systems

The paper presents a real-time operating system (RTOS) with location-transparent system calls that supports multi-core parallel processing and distributed computing in embedded control systems. An application program of an embedded control system is usually designed as a set of tasks that cooperate with each other through the mechanism of a RTOS. Location-transparent mechanisms are required for multi-core and distributed embedded control systems because the tasks are allocated to multiple CPU cores or multiple nodes. We have extended an OSEK OS to provide location-transparent inter-core and inter-node system calls for task management and event control. We have also confirmed that the performance of the RTOS is practical for embedded control systems.
