【摘要】 在分析现有的性能评估方法之上,提出了用MTLS算法对软硬件划分结果进行性能评估,验证系统软硬件划分的优劣。并且针对单任务图描述多CPU系统结构的不足,提出采用多任务图来描述的方法。首先搭建了软硬件协同设计的平台并描述了软硬件协同设计的流程,其次对目标系统进行形式化的描述,最后重点阐述了多任务图的MTLS性能评估算法,并与MD,HNF,HLHET三种算法进行了比较。实验结果表明,提出的MTLS算法比其他三种算法优越。更多还原

【Abstract】 MTLS algorithm is proposed to evaluate the result of Software/Hardware partition and verify the validity of the partition. Multi-Task graph is proposed since the single task graph is not enough to describe the multi-processors system. Firstly, a Software/Hardware codesign system is set up and the flow of Software/Hardware codesign is described. Secondly, the object system is formalized by DAGs. Lastly, MTLS algorithm is discussed in detail. In order to verify the validity of the method, three previous algorithms are suggested. The performance comparison study shows that MTLS algorithm is better than others.更多还原
