Abstract

This
paper presents implementation of a chaotic Cellular Neural Network (CNN) on
Field Programmable Gate Array (FPGA). The network has two non-autonomous cells
and exhibits chaotic behavior. In the implementation stage, Verilog Hardware
Description Language (HDL) is used and discrete time model of the network is
coded on Xilinx ISE Design Suite 13.2. It seems that the chaotic attractor can
be used as entropy source or short key (seed) of chaos based random number
generator design.
