    摘要: Receiver for receiving a data stream via a data bus, which receiver samples the bits of the data stream in an over-sampling process, in which n bit strobe offsets are used and n data sets with i bits are sampled,—applies a decision criterion for identifying those data sets with correct bit values. This decision uses checksum CRC,—selects one of the identified data sets with correct bit values and—uses the bit strobe offset, which was used for receiving the selected data streams, for receiving the data stream. In this way the multiphase clock with optimal phase shifts is selected.

    摘要: In order to carry out in a communication system (1) a temporal synchronization of clocks in a particularly rapid and efficient manner, a method is proposed which has the following steps: acquiring state values which are dependent on a time base (10); filing each acquired state value at a position in a first list L comprising (k+1) positions, if the acquired state value is smaller than or equal to the (k+1) smallest element of the list L, where k is a predefinable error tolerance; filing the acquired state value at a position in a second list H comprising (k+1) positions, if the acquired state value is greater than or equal to the (k+1) greatest element of the list H; forming a mean value from the (k+1) smallest element of the list L and the (k+1) greatest element of the list H, if the number of acquired state values is greater than or equal to (2k+2); determining a correction value as a function of the mean value; and correcting a current state value of the clocks that are to be synchronized.

    摘要: A time-triggered communication system in a dual-channel network of singlechannel architecture, wherein in each case one communication controller (2, 6) is assigned to one channel, and two corresponding communication controllers (2, 6) communicate with one another via an inter-channel interface (1a, 1b). Said inter-channel communication contains information about limiting points (G1, G2 . . . G12) of a time path. A limiting point (G1, G2 . . . G12) is, for example, the point in time when a cycle starts. The interchange of limiting points enables the temporal offset of the two channels to be determined as well as a correction value. After every two cycles also the rate error of the local clocks can be ascertained and a suitable correction value determined. The reliability of safety-relevant networks is increased by the time-triggered communication system described hereinabove.
