The survey on evolvable hardware research

Evolvable hardware(EHW),which combines evolutionary algorithms with reconfigurable hardware,refers to hardware that can change its architecture and behavior dynamically and autonomously by interacting with its environment.Evolvable hardware has been widely used in circuit design,fault tolerance,automatic control,intelligent robotics,pattern recognition and other research areas.In this paper the development of evolvable hardware are reviewed briefly,and the theories and applications are presented in details.The current problems and future research directions are also discussed.
