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.
