支持替代/补偿的实时调度策略

Real-Time Scheduling Strategy Supporting Alternative and Compensate

提出了支持替代 /补偿的实时事务模型 ,该模型上的实时事务具备较强的适应能力和自我纠错能力 ,适合于嵌入式实时数据库系统 .在分析补偿任务的实时性和价值特征的基础上 ,研究了补偿任务的调度时机 ,给出了相应的调度策略和实现算法.

This paper proposed an real time transaction model supporting alternative and compensate. This transaction model suits for embedded real time database systems because it makes transaction has high adaptability and mendability. The paper researched scheduling opportunity of compensate tasks and gived scheduling strategy and realization arithmetic after analyzing compensate task` real timely and value.
