摘　　要：以一种具有时间约束的数据流图DFG的可调度性分析为基础,提出一种软硬件划分算法该算法将由共享资源争用引起的性能影响考虑在内,使得软硬件划分能依据更为精确的性能分析结果,由此将缩小软硬件划分中性能估计同实际运行状况之间的差异,提高划分的合理性。In this paper,based on schedulability analysis of data flow graphs (DFG) with timing constraints, we introduce a hardware?software partitioning algorithm which takes into account contentions. Such an algorithm can lead to a more precise design space exploration, providing the designer an economic way to compare different partitions based on precise performance analysis and find optimal solution in short computation time.
