嵌入式系统软硬件自动划分方法研究

软硬件划分一直是嵌入式系统软硬件协同设计中的难点,如果离开具体系统,单纯的软硬件划分,其性能很难评估。本文提出基于系统体系结构,应用遗传算法来进行多目标优化的软硬件自动划分方法。在具体设计中,使用数据流图对系统建模,采用邻接表进行个体编码,定义交叉、变异操作,同时引入小生境技术,保持解的多样性。该方法为嵌入式系统软硬件自动划分提供一种新思路。

Research on the method of embeded system software/hardware automatic partitioning

The software/hardware partitioning is always difficulty in software and hardware coordination design of the embedded system, not considering the concrete system, but only considering the software/hardware partitioning, the system performance is very difficult to evaluate. The article proposed a method which based on the system architecture and the multi-objectives optimization by the genetic algorithm carried on software/hardware automatic partitioning. In design the article set up the the system model by Data Flow Diagram, then used the adjacency list to code individual, defined the operation of the crossover, mutation, and imported the niche technology which may maintain solution multiplicity. The method provides a kind of new idea for embeded system software/hardware automatic partitioning.
