With the rapid evolution of commercial hardware platforms, in most application domains, the industry has shown a growing interest in integrating and running independently-developed applications of different “criticalities” in the same multi-core platform, with the objective of improving the performance/cost ratio of the system. Such integrated systems are commonly referred to as mixed-criticality systems (MCS). Most of the MCS-related research published in the state-of-the-art cite the safety-related standards associated to each application domain (e.g. aeronautics, space, railway, automotive). However, those standards are not, in most cases, freely available, and do not always clearly and explicitly specify the requirements for mixed-criticality systems. This paper addresses the important challenge of presenting the relevant information available in some of the safety-related standards, such that the mixed-criticality concept is understood from an industrialist’s perspective. In addition, the paper evaluates state-of-the-art mixed-criticality real-time scheduling models and algorithms against the safety-related standards.

关于混合临界系统的共同学术理解的工业观点

随着商用硬件平台的快速演进，在大多数应用领域，业界对在同一个多核平台上集成和运行不同“临界点”的自主开发应用越来越感兴趣，以提高性能/系统的成本比率。这种集成系统通常称为混合临界系统 (MCS)。大多数最新发表的 MCS 相关研究都引用了与每个应用领域（例如航空、航天、铁路、汽车）相关的安全相关标准。然而，在大多数情况下，这些标准并不是免费提供的，并且并不总是清楚明确地指定混合临界系统的要求。本文解决了呈现一些安全相关标准中可用的相关信息的重要挑战，以便从工业家的角度理解混合临界概念。此外，本文根据安全相关标准评估了最先进的混合临界实时调度模型和算法。
