演化硬件容错技术的研究

演化硬件是替代传统硬件设计的新技术,自修复与容错技术是替代现有冗余设计的较为理想的方法,是实现电子设备高可靠、长寿命的重要保证。介绍了演化硬件的容错原则,论述了构建容错系统的两种不同方法,即适应度方法和群体方法;基于反映器件物理"特性"的Messy门,进行演化过程仿真,得到了具有一定容错能力的电路,根据对仿真结果的讨论得出了相应的结论。

Research of EHW fault-tolerance technology

Evolvable hardware is a new hardware design technology to replace traditional methods, its self-repairing and fault-tolerance technology is the ideal method to replace the present redundancy design, and it is important to assure the electronic devices operating with high-reliability and long-lifetime. The fault-tolerance principle of evolvable hardware is introduced, and two different methods: fitness method and population method, building fault-tolerance system are described. Based on the Messy gate which reflects the component physical characteristic, the evolution process is simulated, the evolved circuits with the ability of fault-tolerance are achieved, and the corresponding conclusions are made with respect to the simulation results.
