Field programmable gate arrays can be considered to be the most popular and successful platform for evolvable hardware. They allow to establish and later reconfigure candidate solutions. Recent work in the field of evolvable hardware includes the use of virtual and native reconfigurations. Both of these approaches have their disadvantages. The virtual reconfiguration is characterized by lower maximal operational frequency of the resulting solutions, and the native reconfiguration is slower. In this work, a hybrid approach is used merging the advantages while limiting the disadvantages of the virtual and native reconfigurations. The main contribution is the new low-level architecture for evolvable hardware in the new Zynq-7000 all programmable system-on-chip. The proposed architecture offers high flexibility by considering direct modification of the reconfigurable resources. The impact of the higher reconfiguration time of the native approach is limited by the dense placement of the proposed reconfigurable processing elements. These processing elements also ensure fast candidate evaluation. The proposed architecture is evaluated by evolutionary design of switching image filters. The experimental results demonstrate superiority over the previous approaches considering the time required for evolution, area overhead, and flexibility.
