| 摘 要： | 软硬件划分是嵌入式系统设计的高层抽象环节中最重要的关键步骤之一.在某些数据相关的应用领域中,划分环境是动态变化的,因此我们提出了一种解决动态软硬件划分的方法.这种方法基于一种名为DQCGA的演化算法.DQCGA算法受自然界中对称和互补机制的启发,操纵一对互补的概率向量来适应动态变化的环境.我们系统地完成了建模,动态环境定义等环节,然后通过和已有方法的比较,有针对性地设计了实验.试验结果很好地证明了该方法对于解决软硬件划分问题的可行性和有效性,并且较之以往的方法有着更好的表现.

| Abstract: | HW/SW partitioning is one of key steps in high level abstraction of embedded system co-design.In some kinds of data-dependence applications,the partitioning environment is dynamic.In the paper we present an approach to solve dynamic HW/SW partitioning problem based on a kind of evolutionary algorithm called DQCGA.DQCGA was inspired by Dualism or complementarity in the nature and operated on a pair of dual probability vectors to adapt itself to the dynamic environments.We systematically construct the system ... |
