Evolvable Hardware (EHW) is a reconfigure hardware, which is based on the Programmable Logic Device (PLD). Whenever the environment is changed, EHW can automatically alter its own structure to fit the surroundings.

• 演化硬件(Evolvable Hardware,EHW)是一种可重构的硬件,它建立在可编程逻辑器件之上,每当环境发生变化,演化硬件就自动地改变自身的硬件结构以适应所处的环境。
