进化硬件在数字电路设计中的应用研究

进化硬件在航空航天电子系统中有巨大的应用价值和潜力。目前,电路进化设计是进化硬件研究的主要方向之一。本文介绍了进化硬件的原理,并针对平台中算法的早熟和收敛速度慢的缺点,改进了原有算法。同时,指出不同类型数字电路在进化中的区别,并以典型电路为例分别进行进化,对结果进行了比较分析,验证了所用算法对进化不同类型电路的有效性。

Study on On-line Evolution of Digital Circuits based on Evolvable Hardware

Evolvable Hardware has high value and huge potential use in electronic systems of Aeronautics and Astronautics.At present,the design of evolving circuit is one of major way in study of Evolvable Hardware.This paper introduces the principle of evolvable hardware and the improved algorithm since the original algorithm prone to premature and evolution process is slow.Two examples of the evolution of typical circuits are given and some comparative study of two different types of circuits is made which proves the validity of the algorithm on evolving different types of circuits.
