Abstract
A seedable pseudo-random number generator. A linear feedback shift register (LFSR) arrangement is used to generate a first pseudo-random number, and a cellular automata is used to generate a second pseudo-random number. The bits of the LFSR arrangement are XORed with bits of the cellular automata to generate the output pseudo-random number.
