摘　　要：为解决多任务环境下异构信号处理平台组件化开发过程中,多队列区分服务模型队列数量较多以及性能下降问题,提出一种基于相对优先级的单队列区分服务模型。该模型利用数据标签来标识数据的服务质量要求,由队列管理器计算数据的队列因子,并调整数据在单一待发送队列中的位置,从而达到满足多任务多服务质量要求的目的。仿真结果表明,该模型随任务数量的增加,性能下降并不明显,同时可实现对不同任务的区分服务。In order to solve the problem that the number of queues is large and the performance decreases in multi-queue differentiated service model,which occur in the component-based development of heterogeneous signal processing platform,this paper presents the differentiated service model with a single queue based on relative priority.This model uses data labels to identify quality of service requirements of data.The queue manager calculates the queue factor of the data and adjusts the position of the data in a single queue to be sent,so as to satisfy the requirement of multi tasks and various QoS.The simulation results show that the performance degradation of this model is not obvious with the increasing number of tasks,and this model can be implemented on different tasks of the differentiated services.
