Abstract. This paper presents a real-time full-programmable fuzzy compiler based on piecewise linear interpolation techniques designed to be executed in SIMD (Single Instruction Multiple Data) architectures. A fullprogrammable fuzzy processor is defined as a system where the set of rules, the membership functions, the t-norm, the t-conorm, the aggregation operator, the propagation operator, and the defuzzyfication algorithm can be defined by any valid algorithm. The SIMD platforms selected are the Intel Pentium III (using the SSE set of instructions) and the Texas Instruments TI DSP C6x family. The final speed obtained in both implementations is highly satisfactory and better than the speed provided by standard specific hardware.
