Issues on task dispatching and master replication in FTT-CAN
José Fonseca, Joaquim Ferreira, Mário J.B. Calha, Paulo Pedreiras, Lúıs Almeida · 2003
The FTT-CAN (flexible time-triggered communication on controller area network) protocol supports time-triggered communication in a flexible way as well as the combination of both time and event-triggered traffic with temporal isolation. Previous papers have already discussed its potentialities and presented worst-case temporal analysis for both types of communication. After a brief review of the main characteristics of the protocol, we present new issues concerning its use in distributed embedded systems: the extension for task dispatching and the inclusion of techniques to improve fault tolerance, namely master replication.
