Towards new applications of multi-function logic: Image multi-filtering

Multifunctional (or polymorphic) gates are capable of performing two or more logic functions according to the setting of control signals. They can be considered as building blocks for new and cheap reconfigurable chips. In this paper, we utilized multifunctional components that can be implemented using multifunctional gates as building blocks of image filters. We applied genetic programming to evolve image filters performing different filtering tasks under different settings of control signals. Evolved solutions exhibit a significant reduction in utilized operations and interconnects w.r.t. the multiplexing of conventional solutions.
