An Operating System for Safety-Critical Applications on Manycore Processors
Florian Kluge, Mike Gerdes, Theo Ungerer · 2014
Processor technology is advancing from bus-based multicores to network-on-chip-based many cores, posing new challenges for operating system design. In this paper, we discuss why future safety-critical systems can profit from such new architectures. To make the potentials of many core processors usable in safety-critical systems, we devise the operating system MOSSCA that is adapted to the special requirements prevailing in this domain. MOSSCA introduces abstractions that support an application developer in his work of writing safety-critical applications. Internally, MOSSCA runs in a distributed manner to achieve a high parallelism while still guaranteeing a predictable behaviour.
