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.
