A cellular automaton which generates pseudorandom data comprises a series of cells arranged such that each cell receives signals from electrically adjacent first and second cells. Each cell comprises a D-type flip-flop for storing a data bit, and logic circuitry which couples the flip-flop of the cell to those of associated first and second adjacent cells. The logic circuitry responds to the current state of the data bits stored by a particular cell and its associated first and second electrically adjacent cells by changing the value of the data bit stored by the particular cell according to a predetermined one of the following relationships:
