A sufficient response-time analysis for mixed criticality systems with pessimistic period

The upsurge in many mixed-criticality (MC) system is to integrate multiple functionalities in a common shared hardware platform for lower cost and higher power efficiency. Some functionalities in many safety-critical embedded systems are subject to certification requirements. These MC systems generate challenges in run-time monitoring and static schedulability analysis. In prior researches, many papers studied the response-time analysis algorithm in MC systems considering pessimistic WCET parameter. But in some real MC systems, the tasks with pessimistic period usually exist. In this paper, we presents a sufficient adaptive response-time analysis (SAMC) for MC systems considering pessimistic period parameter and optimal priority assignment scheme for fixed-priority uniprocessor scheduling of MC system with dual-criticality levels.
