One of the main obstacles in using the modern processors [11]-[13], [23]. The most important drawback of fuzzy control theory in engineering applications is its very high the previous published work is that there is no inclusive computational cost with respect to common traditional analysis on different software necessities of different fuzzy approaches. This paper focuses on improving the execution time applications to propose a comprehensive set of fuzzy of software implementation of different fuzzy applications on various processors. A Platform-Independent Fuzzy Instruction imstructions. Some of the proposed instructions are too simple set Extension (PiFie) is introduced in this paper. It contains [11], [12], while some others are too fuzzy specific and sixteen different instructions which can significantly accelerate complex [13], [23]. It is important to note that as the main
