Since the birth of the Evolvable HardWare (EHW) research field, many FPGA-based evolvable hardware techniques have been devised and proposed to the scientific community. Even if newer EHW systems introduce improvements and new features with respect to the older ones, in most cases they are still based on outdated FPGAs. Thus, they are often limited by the amount of available resources and by the capabilities of the devices used. This paper describes an EHW system based on a Xilinx Virtex-4 FPGA able to exploit features like the direct bitstream manipulation and the two-dimensional dynamic reconfiguration mechanism.
