| 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，也使得目标系统的性能获得更可靠的保证．

| Abstract: | 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. |
