Abstract
A method for generating multiple arbitrarily shifted pseudorandom bit streams from a single linear feedback shift register (LFSR) is presented. Each bit stream is obtained by tapping the outputs of selected LFSR cells and feeding these tapped cell outputs through a set of exclusive-OR gates. This enables many neurons to share a single LFSR, resulting in an acceptably small overhead for VLSI implementation
