A unified approach for memory protection in a bare-metal and a real time operating system

In modern time almost all safety critical applications employ a Real Time Operating System(RTOS) to efficiently perform different embedded operations by using the powerful resources available on the silicon chip. As multiple tasks run in parallel in RTOS therefore they might intrude into each other's memory area and can corrupt someone else's data and as the result the running application can be crashed and it can bring down the whole system. Memory protection mechanism can guarantee that the system can be guarded against this intrusion. In this paper a unified approach has been presented to successfully implement the memory protection in a bare-metal and Real Time Object Oriented Dependable Operating System (RODOS).
