Abstract
A safety architecture system includes, in one aspect, a first stage comprising a primary unit that generates primary data for performing normal system functionality; a secondary unit that generates secondary data for performing alternative system functionality; a primary safety gate coupled to the primary unit, with the primary safety gate providing the primary data as a primary output responsive to a determination of validity of the primary data; and a secondary safety gate coupled to the secondary unit, with the secondary safety gate providing the secondary data as a secondary output responsive to a determination of validity of the secondary data. The system also includes an output selector that is coupled to both the primary safety gate and the secondary safety gate of the first stage, with the output selector providing a system output responsive to the determinations of the validities of the primary data and the secondary data.
