FPGA-implementation of high-speed MLP neural network

This paper presents a new high-speed FPGA implementation of a pipelined adaptive multilayer perceptron (MLP). The proposed approach is a fully parallel architecture based on the delayed backpropagation algorithm, which permits to reduce the critical path and consequently increases the operating frequency. Results obtained with nonlinear function approximation show that this pipelined parallel architecture is four times faster than the conventional one.
