1. A machine for improved generation of pseudo-random numbers in a computer system, comprising: a processor or microprocessor coupled to a memory, wherein the microprocessor is programmed to generate a pseudo-random number using the output from the center bit of a bounded one-dimensional cellular automaton with a fixed span and an extreme left boundary cell and an extreme right boundary cell, wherein a left linear feedback shift register provides continuous input to the extreme left boundary cell, and a right linear feedback shift register provides continuous input to the extreme right boundary cell.
