Industrial Approach for Dependability

This presentation introduces author´s and (his affiliation´s) industrial approach for dependability. The author´s affiliation has long history of dependable system technology starting with railway and nuclear power generation fields. The author proposed self-checking techniques and optimal time diversity method to maximize fault detection and recovery coverage to realize ultimate high-reliability at the middle of 1990´s. The technology established thus was applied to the railway control system such as electronic railroad crossing controllers starting with LSI (Large -Scale Integration Circuit) for ATP (Automatic Train Protection). The authors applied the ultimate high-reliable technologies to on-chip redundancy, which has redundant cores within one chip in 2000´s when multi-core processors which have plural processor cores within one chip appear as a result of development of high-density integration by the Moore´s Law. At the end of the presentation the author introduces X-by-Wire technology which challenges to control automotives with computer assistance as the latest application and the most prospective application of dependable LSI technology.
