介绍了演化硬件(Evolvable Hardware,EHW)的基本原理,在分析了现有演化平台的基础上,针对现有演化平台扩展复杂、配置位不公开等缺点,提出了基于GAL(Generic Array Logic)软核的EHW平台,并进行了原型实现和演化实例验证.最后将基于GAL软核的EHW平台与现有演化平台进行了对比分析,实验结果和对比分析表明该平台具有配置位公开、配置速度快、扩展灵活等优点,可以为演化平台系统设计提供参考.
This paper introduces the basic principle of Evolvable Hardware (EHW). Based on the analysis of the existing evolution platform, aiming at the disadvantages of the existing evolution platform, such as the complicated extension and the open configuration bits, Nuclear EHW platform, and carried out the prototype implementation and evolutionary instance verification.Finally, the EHW platform based on GAL soft core is compared with the existing evolution platform, the experimental results and comparative analysis show that the platform has the configuration bits open, fast configuration , Expand the flexibility and other advantages, can provide reference for the evolution platform system design.
