Evolvable Hardware in Xilinx Xcr3064 Cpld

Evolvable Hardware (EHW) is a hardware which modifies its own structure in order to adapt to the environment in which it is embedded. This reconfigurable hardware is implemented on a programmable circuit, whose architecture can be altered by downloading a binary bit string. These bits are adaptively acquired by evolutionary algorithms. In this paper we have used an evolutionary algorithm to design some combinational and sequential logic circuits. These designs have been implemented in a real Xilinx XCR3064 CPLD and have been compared with other designs created by manual methods or other heuristic techniques. A better fitting of circuit resources have been observed in almost all evolutionary designs. Copyright © 2004 IFAC
