Energy-Efficient Deterministic Fault-Tolerant Scheduling for Embedded Real-Time Systems
摘要
Abstract
By combining fault-tolerance with power management, this paper developed a new method for aperiodic task set for the problem of task scheduling and voltage allocation in embedded real-time systems. The schedulability of the system was analyzed through checkpointing and the energy saving was considered via dynamic voltage and frequency scaling. Simulation results showed that the proposed algorithm had better performance compared with the existing voltage allocation techniques. The proposed technique saves 51.5% energy over FT-Only and 19.9% over FT+EC on average. Therefore, the proposed method was more appropriate for aperiodic tasks in embedded real-time systems.关键词
