高层次综合已成为当前设计流程中的一个热点 ,而算子调度是高层次综合中的一个关键步骤。文章基于传统的力量引导调度算法 ,通过在每次调度决策时引入可测性考虑 ,使最终设计的可测性得到提高。另外还建立了一个新的算子分布概率模型 ,可以有效地处理多周期算子的调度。对几个基本测试电路的实验表明了此算法的有效性。 High-level synthesis has become a hot spot in the current design process, and operator scheduling is a key step in high-level synthesis. Based on the traditional power-guided scheduling algorithm, this paper improves the testability of the final design by introducing testability considerations in each scheduling decision. In addition, a new operator distribution probability model is established, which can effectively handle the scheduling of multi-periodic operators. Experiments on several basic test circuits show the effectiveness of this algorithm.
