Most published works usually focused on extrinsic evolvable hardware (EHW), and in some instances, intrinsic but offline adaptive EHW. In this paper, we describe an intrinsic evolvable and online adaptive EHW to solve packet switching problem. Based on the coding and evolution scheme, we refer to it as evolvable fuzzy hardware (EFH), an extension of our proposed evolvable fuzzy system (EFS) by Li and Lim (2003) and reconfigurable fuzzy inference chip (RFIC) by Cao et. al. EFH is a good framework for intrinsic evolvability and online adaptation.
