Fast Prototyping of Artificial Neural Network: GSN Digital Implementation

This work describes a framework for a GSN (Goal Seeking Neuron) Boolean neural network fast prototyping into a user-programmable gate array. This system provides a VHDL language description of the trained network, allowing the direct implementation of the circuit on an academic FPGA (Field-Programmable Gate Array). A GSN software tool was designed to train and simulate a user-defined network, with diverse dimensions and applications. The implemented network presents 60 neurons in four pyramids with four layers. The short propagation time (30 ns) of the network output provides the requirements to deal with real time neural
