Memory Protection in a Real-Time Operating System

During the last years the number of Electrical Control Units (ECU) in vehicles have increased rapidly with the effect of increasing costs. To meet this trend and reduce costs, applications have to be centralized into more powerful ECUs. This gives rise to new problems such as data and temporal integrity. The thesis gives an introduction to these new problems and a solution based on static time-triggered scheduling combined with memory protection. Memory protection mechanisms and hardware are evaluated, resulting in the recommendation of a platform. The thesis also propose modification and extensions to a real-time operating system used today within the Volvo Group. The work has been conducted at Volvo Technology (VTEC) in Gothenburg. VTEC is a combined research and consulting company within the Volvo Grou
