中文摘要：
在多核嵌入式系统中，避免总线冲突并在时间限制下调度通信任务和计算任务来降低能量消耗是非常重要的，有效节能调度可以避免总线冲突并在时间限制下实现有效节能。由于任务的粒度、优先级、通信任务和计算任务的协同调度对此类算法的节能有着重要影响，概述了这三个方面的研究现状，指出总线冲突避免的节能调度算法设计中有待解决的问题，并给出了多核嵌入式系统总线冲突避免的节能调度算法的发展方向。
英文摘要：
In multi-core embedded systems, it is very important to avoid bus collision and reduce energy consumption by scheduling both communication tasks and computation tasks under timing constraint. Effective energy efficient scheduling can avoid bus collision and implement effective energy saving under time constraints. Because granularity and priority of tasks, co- scheduling of communication tasks and computation tasks have an important effect on energy saving of such kind of algorithms, this paper summarized the research status of these three aspects. It pointed out the problems to be solved from the design of en- ergy-saving scheduling algorithms in bus collision avoidance and gave the development direction of energy saving scheduling al- gorithms in bus collision avoidance for multi-core embedded system.
