Automotive safety concept definition for mixed-criticality integration on a COTS multicore

Mixed-criticality systems integrating applications subject to different safety assurance levels into the same multicore embedded platform can provide potential benefits in terms of performance, cost, size, weight, and power. In spite of this evidence, however, several hard challenges related to the safety certification of multicore approaches must be considered before endorsing their unrestrained adoption. This paper describes an ISO-26262 compliant safety concept for an automotive mixed-criticality case-study on top of a multicore platform. To this end, key aspects such as time and space partitioning are evaluated and enforced by means of hardware protection mechanisms
