摘　　要：为了满足复杂嵌入式实时系统中应用任务对计算的需求,提高计算有效性,将多态实时计算的概念引入众核架构中,设计了一种众核多态实时计算模型。提出了计算态的概念,并设计了三种计算态以适用于不同类型任务。仿真测试结果表明,在较低通信衰减的情况下,此众核多态实时计算模型使应用任务在以不同计算态进行计算时均可获得较高的加速比,从而提高了系统对计算量大的应用任务的响应速度。In order to improve the computational efficiency and fit the needs of complex embedded real time systems,the concept of polymorphic real time computing is introduced in many-core parallel architectures. A polymorphic real time computational model is designed and the concept of computating mode is proposed.The paper design and test three types of computing mode for computational model. The results and their analysis show preliminarily that the proposed model in different computing modes can obtain higher speedup under lower attenuation of communication and the response time of tasks is reduced.
