Abstract

Multi-core technology can provide valuable benefits for improving safety critical embedded systems. Examples range from multiple core architectures, introducing system redundancy, asymmetric multiprocessing allowing high software diversity, to hyper visors reducing system complexity. Can these benefits be taken for granted without considering the drawbacks and effects that come with them? The move to multi-core based architectures is already underway. Sooner, rather than later, we are forced to discover and resolve its issues for safety related applications. This paper is an attempt to evaluate the value of multi-core for safety critical systems on a broader level.
