提出了一种从单个线性反馈移位寄存器（LFSR）产生多个任意移位的伪随机比特流的方法。每个比特流通过分接所选LFSR单元的输出并通过一组异或门馈送这些分接的单元输出来获得。这使得许多神经元能够共享单个LFSR，从而为VLSI实现带来可接受的小开销。这种技术已被纳入一个神经网络芯片，使用随机稳定。其他可能的应用包括高速数字通信系统的测试。<><ETX>
A method is presented for generating multiple, arbitrarily shift, pseudorandom bit streams from a single linear feedback shift register (LFSR). 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 acceptable small overheads for VLSI implementation. This technique has been incorporated in a neural network chip that uses stochastic settling. Other possible applications include the testing of high-speed digital communication systems.<<ETX>>
