Mixed-criticality scheduling in real-time multiprocessor systems

Abstract

The relevance and popularity of mixed-criticality real-time systems precipitously increase in many industrial domains. Today, mixed-criticality systems are increasingly being implemented on multicore platforms. So, one of the most actual and important problem in the field of mixed-criticality system is a scheduling tasks with different criticality levels on multiprocessors. In this paper, we will describe the main features of mixed-criticality systems. These include basic methods of its organization and main issues of mixed-criticality scheduling for multicore platforms. Moreover, we will report kinds of multiprocessors, types of multiprocessor scheduling, standards, concepts and research projects, related to mixed-criticality systems. At last, we will detail and compare several mixed-criticality scheduling approaches for multiprocessors.
