Title:
TIME-TRIGGERED COMMUNICATION SYSTEM AND METHOD FOR THE SYNCHRONIZED START OF A DUAL-CHANNEL NETWORK
Document Type and Number:
WIPO Patent Application WO/2004/105326
Kind Code:
A2
Abstract:
A dual-channel network with in each case one communication controller (2, 6) for each of the two channels (A, B). In order to ensure that the two channels (A, B) operate on a temporally matched basis, an exchange of current states ('ready, 'abort') takes place via an external or an on-chip interface (l a, 1b). The cold start operation is carried out only if, and so long as, both communication controllers are in the 'ready' state.
