Abstract: On the basis of the user’s requirement and to the design points of the tolerant computer’s reliability, this paper introduces an embedded redundant computer’s composing and principle, puts forward the tolerant technology’s selection and application including selection of redundant and synchronization mode and design of voter, and presents the hardware’s reliable design means and the software’s design idea. Experiments approve the redundant computer’s reliability.

Key words: redundant, vote, synchronization
