From a Federated to an Integrated Architecture for Dependable Embedded Systems

Abstract

TIME-TRIGGERED ARCHITECTURE (TTA) is an integrated architecture for the implementation of large distributed real-time control systems in high-dependability applications. The TTA realizes the positive aspects of integration such as: (i) significant reduction of the software cost by the strong support for composability, diagnosis, and the re-use of services; (ii) significant reduction of the hardware cost and of the wiring points (reliability improvement); (iii) architectural support of the implementation of fault tolerance; (iv) increased potential and flexibility of function integration while minimizing the negative impact of integration; (v) error propagation from one DAS to another DAS; (vi) blurring of responsibility during system integration; (vii) difficulties in diagnostics.
