Neuro-Fuzzy Computing System with the Capacity of Implementation on Memristor-Crossbar and Optimization-Free Hardware Training
In this paper, first we present a new explanation for the relation between
logical circuits and artificial neural networks, logical circuits and fuzzy
logic, and artificial neural networks and fuzzy inference systems. Then, based
on these results, we propose a new neuro-fuzzy computing system which can
effectively be implemented on the memristor-crossbar structure. One important
feature of the proposed system is that its hardware can directly be trained
using the Hebbian learning rule and without the need to any optimization. The
system also has a very good capability to deal with huge number of input-out
training data without facing problems like overtraining.Comment: 16 pages, 11 images, submitted to IEEE Trans. on Fuzzy system
Memristor-based Circuits for Performing Basic Arithmetic Operations
In almost all of the currently working circuits, especially in analog
circuits implementing signal processing applications, basic arithmetic
operations such as multiplication, addition, subtraction and division are
performed on values which are represented by voltages or currents. However, in
this paper, we propose a new and simple method for performing analog arithmetic
operations which in this scheme, signals are represented and stored through a
memristance of the newly found circuit element, i.e. memristor, instead of
voltage or current. Some of these operators such as divider and multiplier are
much simpler and faster than their equivalent voltage-based circuits and they
require less chip area. In addition, a new circuit is designed for programming
the memristance of the memristor with predetermined analog value. Presented
simulation results demonstrate the effectiveness and the accuracy of the
proposed circuits.Comment: 5pages, 4 figures, Accepted in World Conference on Information
