Response Time Analysis of An Automotive Use-Case Based Two-Level Mixed Criticality System

The evolution of information technology and the tendency of more functionality-centralized controllers has made it possible to schedule tasks with different criticality within the same computing platform on automotives. Unfortunately, a huge gap still remains between academic study of the mixed criticality system and automotive practice. To address the issues when applying the traditionally popular mixed criticality models to practice, an automotive use-case mixed criticality model is proposed. By adopting response time analysis of fixed priority scheduling technique, an implementation of AUB-MCS is accomplished and effectiveness are proved with schedulability test evaluation.
