VLSI Implementation of Fuzzy Logic Operator Unit

摘要

Fuzzy logic is widely used in many applications that deal with uncertainty andapproximate reasoning in decision making. Decisions can be made based on fuzzy inferences. Because of the ease with which Very Large Scale Integration (VLSI) circuits can be made, hardware implementation of fuzzy logic is thus seen to be an appropriate step to be taken to fully realize its potential. Fuzzy operations are based on three basic operators, the maximum, minimum and inverse functions. This thesis investigates its implementation in VLSI circuits, specifically for digital systems. Design structures such as bit-cascade, bit-slice, block-cascade and block-slice were implemented. Comparisons between these designs are provided.
