Sumario:This paper presents an architectural proposal for computing the generalized centroid of an interval type two fuzzy set using the enhanced Karnik Mendel algorithm. The architecture is adapted so that CORDIC based operators can be used to compute multiplications and divisions. In addition, two hardware implementations of the proposed architecture are described. The first one uses conventional parallel operations, while the latter includes CORDIC based operators. Both implementations are achieved over Field Programmable Gate Array technology. They are validated by computing the centroid of twelve deterministic interval type-2 fuzzy sets. Performance indices like area and maximum operation frequency are obtained in order to establish a comparative framework.
