摘　　要：针对传统软硬件划分算法对硬件资源的使用效率考虑不足的问题,提出改进的模拟退火划分算法。该算法对成本函数中的执行时间和面积使用提供附加权、减少权值的动态加权策略,并考虑了一个移动的性能改变对系统面积的影响。实验表明,改进的模拟退火划分算法收敛速度快,得到的解更优,保证了系统硬件资源的有效利用。Aimed at a solution to traditional hardware and software partitioning algorithm affected by the insufficient consideration of efficient use of hardware resources, this paper proposes an improved sim- ulated annealing algorithm. The algorithm works by providing additional weighting and reducing the dy- namic weighting strategy of the weight in execution time and area in the cost function, with the accompan- ying consideration of the effect of a moving performance changes on the system area. Experiments show that the improved simulated annealing algorithm exhibits a faster convergence and better solutions, ensu- ring the efficient use of hardware resources.
