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 comprehensive system composed of hardware and software. Its traditional hardware-first design method has many drawbacks, such as long design cycle and high cost. Hardware and software co-design is to solve the above problems and put forward a new system design ideas. Hardware and software partitioning is the key technology in hardware and software co-design. Among them, the common problem faced by partitioning algorithm is running slowly and inefficiently, resulting in poor performance and cost-effective partitioning result. The partition algorithm is further studied and an improved scheme of genetic algorithm is given.
