Description
The TTP/C-C1 communications controller is the first integrated device supporting serial communication according to the TTP/C specification (time triggered protocol class C). It performs all communications tasks such as reception and transmission of messages in a TTP/C cluster without interaction of the host CPU. TTP/C provides mechanisms that allow the deployment in high-dependability distributed real time systems. It provides the following services:
· predictable transmission of messages with minimal jitter
· fault-tolerant distributed clock synchronisation
· consistent membership service with small delay
· masking of single faults
