Abstract:

In order to realize highperformance and lowpower computing with task partitioning as the study object,the heterogeneous reconfigurable computing definition and its formal description were proposed and two task partitioning methods,intranode recombined and network rebuild,were presented based on matching heterogeneous computing task with reconfigurable architecture.Then the algorithm was derived.Theoretical analysis and simulations prove the taskpartitioning algorithm to be valid.

Key words:directed acyclic graph（DAG）; heterogeneous computing task; reconfigurable architecture; task partitioning
