Parallel Fixed Point Implementation of a Radial Basis Function Network in an FPGA

Parallel Fixed Point Implementation of a Radial Basis Function Network in an FPGA

This paper proposes a parallel fixed point radial basis function (RBF) artificial neural network (ANN), implemented in a field programmable gate array (FPGA) trained online with a least mean square (LMS) algorithm. The processing time and occupied area were analyzed for various fixed point formats....
