摘要
嵌入式系统是一种由硬件和软件构成的综合系统。其传统的硬件先行的设计方法存在许多弊端,如:设计周期长,费用高等。软硬件协同设计是为解决上述问题而提出的一种全新的系统设计思想。软硬件划分是软硬件协同设计中的关键技术,其中,划分算法所面临的共同问题是运行速度慢,效率太低,导致划分结果不能获得很好的性价比。对划分算法作了进一步研究,并给出了遗传算法的改进方案。
Embedded system is a synthetical system composed of hardware and software. However, the traditional device ways of hardware antecedency have many abuses, such as long period, high expense and so on. In order to resolve these problems, we put forward a new idea of system device：HW/SW codesign. Hardware-Software dividing is a key technology. In which, the common problems of dividing algorithms are slow speed, low efficiency. These bring on dividing results＂ low ratio of performance-to-price. Aimming at these problems, the paper does more research for dividing algorithms and gives improvement scheme for genetic algorithm.
