Empirical Study of Energy Minimization Issues for Mixed-Criticality Systems with Reliability Constraints

چکیده
This paper empirically studies the energy minimization problem on a mixed-criticality system with stringent reliability and deadline constraints. To address this problem, we first analyze the resource demand of a mixed-criticality task set with both reliability and deadline constraints. Based on the analysis, we present our heuristic search based energy minimization algorithm (HSEM), which is used to find a task execution strategy that can not only satisfy task set’s reliability and deadline constraints, but also minimize system’s total energy consumption. The performance of our proposed HSEM is compared with two baselines, i.e., the largest utilization first (LUF) and the smallest utilization first (SUF) algorithms. The experimental results indicate that the HSEM algorithm outperforms the SUF and LUF algorithms with respect to energy saving.
