現今第二型模糊邏輯理論是以Zadeh所提出的延伸定理為基礎，其觀念為"對同一件事物的形容，不同人會有不同的語義形容詞\"的集合論上定義，此為模糊集合上最主要的不確定因素。本篇論文中，我們提出一個適用類梯形歸屬函數之第二型模糊推論處理器。我們所提出的架構，特色在於利用間隔集合(IntervalSet)的特性經管線化與平行化的技術設計出第一個具備第二型模糊推 論能力之硬體系統架構，並將高複雜度的不確定因素效應也考慮在其中設計與測試。我們使用TSMC0.35μm標準元件庫，來實現此模糊推論處理器。經由時序分析，我們發現其推論速度可達3.125MFLIPS.

Type-2 Fuzzy Logic is based on the extension principle proposed by Zadeh. The main concept of type-2 fuzzy logic is that“words mean different things to different people"; thus， there are uncertainties associated with words. In this paper， we propose a type-2 fuzzy inference processor that is well suited for trapezoid-shaped membership functions. To the best of our knowledge， our architecture is the fIrsthardware implementation for type-2 fuzzy inference execution. The main feature of the proposed architecture is that it can utilize the features of interval sets. Therefore， the uncertainties can be taken into account. Moreover， in order to speed up the inference execution， pipeline and parallelism techniques are exploited. We use a TSMC 0.35μm standard cell library to implement the proposed architecture. Implementation data shows that the inference speed reaches up to 3.125 MFLIPS.
