Implementing Neural Network-Based Equalizers in a Coherent Optical Transmission System Using Field-Programmable Gate Arrays

A Hardware Implementation of Artificial Neural Network Using Field Programmable Gate Arrays

An artificial neural network algorithm is implemented using a field programmable gate array hardware. One hidden layer is used in the feed-forward neural network structure in order to discriminate one class of patterns from the other class in real time. With five 8-bit input patterns, six hidden nodes, and one 8-bit output, the implemented hardware neural network makes decision on a set of inpu...

Delay-based Pattern Recognition Using Field-programmable Gate Arrays

Implementing a Fuzzy System on a Field Programmable Gate Array

Fuzzy controllers are traditionally implemented in a microprocessor and they produce relatively raw surfaces. The purpose of this work is to implement a fuzzy control system in a FPGA and to have resulted control surface as smooth as possible. The FPGA has allowed designers to create large designs test them and make modifications very easily and quickly. This approach uses a new weighted averag...

Regular datapaths on field programmable gate arrays

Field-Programmable Gate Arrays (FPGAs) are a recent kind of programmable logic device. They allow the implementation of integrated digital electronic circuits without requiring the complex optical, chemical and mechanical processes used in a conventional chip fabrication. FPGAs can be embedded in traditional system designflows to perform prototyping and emulation tasks. In addition, they also e...
