Abstract

A hardware accelerator that performs fuzzy learning, fuzzy inference, and defuzzification strategy computations is presented. The hardware is based on two-valued logic. A universal space of 25 elements with five levels each is supported. To achieve a high processing rate for real-time applications, the basic units of the accelerator are connected in a four-level pipeline. The accelerator can receive two parallel fuzzy data as inputs. A flag will be set if the fuzzy model R(u,w), constructed in a learning process, exhibits the property as follows: for all (u,w) belonging to the set U×W, R(u,w) = 1. At a clock rate of 20 MHz, the accelerator can perform more than 1,400,000 fuzzy logic inferences per second on multi-dimensional fuzzy data.
