The clock supervision unit (100) analyzes the at least one clock (c*) based on a monitor clock (m*) provided together with the at least one clock (c*) or separately to the clock supervision unit (100). The clock supervision unit (100) at least comprises an activity unit (210), a deviation unit (220) and an auxiliary clock generator (240). The auxiliary clock generator (240) outputs an auxiliary clock (a*). The activity unit (210) detects the presence of the monitor clock (m*) based on the auxiliary clock (a*) and the presence of the auxiliary clock (a*) based on the monitor clock (m*). The deviation unit (220) detects clock faults in the monitor clock (m*) based on the auxiliary clock (a*). With the clock supervision unit (100) according to the present invention, the at least one clock (c*) can be supervised in more detail and it is possible to react on different clock faults in the at least one clock c* with different error handling procedures, e.g. by initiating a shutdown of the devices controlled by the electronic system.

    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: The invention relates to a method of transmitting user data via a communications medium (2) between subscribers (3) connected to the communications medium (2), wherein the data are transmitted in recurrent cycles (8) and at least one slot (9, 10) in each cycle (8) is intended for the user data of at least one subscriber (3). In order to permit a particularly efficient data transmission via the communications medium (2) at least one of the slots (10) is used to transmit the user data of different subscribers (3) (A, C, F) in different cycles (8). In addition, a bus guardian (6) of one subscriber (3) determines whether the subscriber (3) may transmit user data in the current slot (9, 10) of the current cycle (8), the bus guardian (6) having at least indirect access to a universal condition available throughout the entire communications system (1). In particular, an internal counter of the bus guardian (6) is synchronized to a universal cycle counter.
