The number of electronic applications using fuzzy logic-based solutions has increased considerably in the last few years. Concurrently; new CAD tools that explore different implementation technologies for this type of systems have been developed. In this paper we illustrate a fuzzy logic system design strategy based on a high level description. Employing this high level description; the knowledge base is translated to a format in appearance close to the natural language with the particularity that it uses a hardware description language (VHDL) directly synthesizable on an FPGA circuit. In addition; we analyze different approaches for FPGA implementations of fuzzy systems in order to characterize them in terms of area and speed. Among them; the use of specific processing architectures implemented on FPGAs presents as main advantages a good cost-performance ratio and an acceptably short development time. The different synthesis facilities provided by the Xfuzzy design environment for the implementation of programmable fuzzy systems; which take advantage of the available resources in the current FPGA families; are also analyzed in this paper. © 2005 Elsevier Inc.
