中文摘要:
      提出了一个用于基于虚拟可重构结构(VRA)的演化硬件的自适应变异参数控制方法,该方法有效且易于硬件实现。在一个完全由现场可编程门阵列(FPGA)实现的基于VRA的内部演化硬件上建立了试验平台。变异比率控制参数也编码到染色体中作为附加的基因经历演化过程。通过和传统的采用固定变异比率的演化算法在演化4位偶校验函数、2位乘法器和3位乘法器的对比实验可以看出,这种采用自适应变异比率控制的演化算法的性能明显优于传统的采用固定变异比率的演化算法。
英文摘要:
      This paper proposes an efficient and hardware feasible self adaptive mutation rate control scheme for the virtual reconfigurable architecture (VRA) based evolvable hardware (EHW). The experimental platform was built on a complete FPGA implemented intrinsic EHW which was based on VRA. The mutation rate control parameters were encoded as additional genes in chromosome and also underwent the evolutionary operations. The strength of the proposed method was demonstrated by a comparison of its performance with that of the traditional evolutionary algorithm (EA) with the fixed mutation rate on the evolutions of a 4 bit even parity function, a 2 bit multiplier and a 3 bit multiplier. Within the range of the experiments, the performances of the proposed scheme were remarkably better than that of the conventional constant mutation rate based EA.
