Microelectronic Systems for Computational Intelligence

Keywords: intelligent systems; soft-computing; neuro-fuzzy circuits; CAD tools; model-based design; fuzzy control; fuzzy image processing; internet of things

This research line focuses on the development of new design methodologies and circuit elements for Computational Intelligence applications. Computational Intelligence includes a set of techniques inspired by natural processes that allow addressing complex problems more efficiently than through traditional approaches. Specifically, our interest is mainly focused towards efficient hardware implementation of neuro-fuzzy systems and its use in applications that take advantage of their ability to describe a system with linguistic terms, as well as to cope with the inaccurate, vague or incomplete information that appears in many real-world problems.
In recent years, the developed activities in this line have addressed the following three main objectives:
  1. The development of architectures for efficient implementation of fuzzy-inference systems on ASICs and FPGAs, as well as the proposal of a model-based design methodology that accelerates the stages of functional verification and synthesis of fuzzy modules and facilitates their integration in embedded systems.
  2. The generation of a development environment for fuzzy systems, Xfuzzy, which facilitates the tasks of design, verification and synthesis, both software and hardware, of fuzzy logic-based systems.
  3. The application of the above techniques and circuits to different problems of robotics, industrial control, food technology, communications systems, image processing, and intelligent device networks for applications related to the areas of safety and environmental control.
