| 摘 要： | 为降低可重构媒体处理器任务编译器设计中系统配置代价,有效提升配置信息的配置效率,提出了一种新的配置信息优化生成方法。该生成方法在对输入的数据流图进行独立子图搜索和子图同构判定得到各类子图的属性的基础上,对配置模板生成步骤增添约束来生成全等的配置模板以提升系统的配置性能。本文方法已被应用到可重构媒体处理器任务编译器的设计实践中。实验结果表明:本文方法能够有效地生成优化的配置信息,所生成的配置信息的配置性能明显优于传统贪婪方法生成的配置信息。

| Abstract: | Generating the configuration contexts is one of the key challenges in the design of task compiler for reconfigurable media processors.In order to reduce configuration cost,a novel configuration contexts generation method is proposed.The sub-graph searching and graph isomorphism algorithms are introduced to obtain graph attributes,and the constraints of generating congruent configuration template are add to promote the configuring performance.The proposed configuration contexts generation method was used in the design of task compiler for reconfigurable media processor.Experimental results show that the proposed method can generate the configuration contexts effectively and the configuring performance is significantly higher than that of traditional greedy generation method. |
