摘 要：正The cosynthesis problem addressed in this paper involves three subproblems:selection of appropriate processing elements, mapping and scheduling of function blocks to the selected processing elements,and schedulability *** have presented a cosynthesis framework in our earlier work[1]that defines an iteration loop of three steps that attack the subproblems *** many good features,our previous technique has a severe restriction that a task monopolizes the entire system once *** in general we may obtain higher performance if multiple tasks can be running concurrently on different processor *** is the main contribution of this paper that we extend the previous framework to be applicable for general multiprocessor systems with diverse operating *** demonstrate the performance improvement from the proposed work with a multi-media real-time application,DVR system,and randomly generated multi-task graphs.
