摘　　要：探讨提高嵌入式系统中并发事务调度效率的设计方法。通过采用增加中间调度代理层的设计架构,改变传统事务请求的接入控制。结果表明,采用代理调度模型的设计,可减少并发事务的直接耦合程度,改善系统处理并发事务的整体性能。代理调度模型设计是通过预计算的时间代价,来换取调度并发事务的冲突避免。This issue presents a novel architecture design for improving the concurrent tasks scheduling efficiency.By attaching the intermediate scheduling agent,this design can improve the admission control that the traditional tasks scheduling design requires.The experimental results show that the agent structure can decrease the concurrent tasks coupling degree,and further advance the scheduling efficiency.The agent scheduling architecture design sacrifices pre-computational time cost for avoiding the concurrent tasks execution collision.
