摘      要：This paper presents a method to reduce the energy consumption of multi-core systems characterized by processor cores and buses with discrete frequency levels under timing *** proposed method takes the transformations of the original task graphs,which include dependent tasks located in different iterations,as *** proposed method utilizes mapping selection as well as joint processor and communication frequency scaling to implement energy *** conduct experiments on several random task *** results show that the proposed method can achieve substantial energy reduction compared with previous work under the same hard timing constraints.
