摘要:
软硬件划分是动态可重构系统软硬件协同设计中的关键技术之一,如何兼顾划分效率和划分效果,达到两者的最佳结合是软硬件划分的主要问题。在考虑动态部分重构及重构延时等特征的基础上,提出一种微粒群优化算法与混沌优化算法相结合的混沌微粒群软硬件划分方法。该算法使用基于实数编码的微粒群优化算法执行全局搜索,再根据搜索结果采用混沌优化算法执行局部搜索,具有较强的全局搜索和跳出局部最优的能力。仿真实验表明,该算法比标准微粒群算法和遗传算法具有更好的有效性和快速性,能够有效地实现应用任务图到可重构系统的时空映射
Abstract:
Hardware/software partitioning is an important technology in hardware/software codesign of dynamically reconfigurable system. How to keep the balance between the speed and performance is the key problem. Considering the partially run-time reconfiguration and reconfiguration delay of reconfigurable system, a chaotic particle swarm optimization algorithm is proposed which combines the particle swarm optimization （ PSO） and chaotic optimization algorithm （ COA）. This algorithm uses PSO based on real coding to search globally, and then uses COA to search locally, has strong ability of searching and getting out of the local optimum. The experimental results show that the method can efficiently map the task graph to reconfigurable system,and get better partitioning results and executing speed than the method based on PSO or genetic algorithm （ GA }.[
