摘要： A method and a bit stream decoding unit for bit stream decoding has a bit stream comprising a number of consecutive samples. In order to provide for rapid and, in particular, reliable decoding of the bit stream, a detection window comprising a number of samples is defined and the detection window is positioned at certain positions on the bit stream in order to comprise certain samples with respective sample values. A majority voting is applied to the sample values in the detection window and, in dependence on the result of the majority voting, the bit stream is decoded and respective bit values are generated.

摘要： The invention refers to a method for monitoring a communication media access schedule of a communication controller (5) of a communication system (1) by means of a bus guardian (6). The communication system (1) comprises a communication media (2) and nodes (3) connected to the communication media (2). Each node (3) comprises a communication controller (5) and a bus guardian (6) assigned to the communication controller (5). Messages are transmitted among the nodes (3) across the communication media (2) based on a cyclic time triggered communication media access scheme. In order to provide a mechanism which allows the bus guardian (6) to monitor the communication media access scheme of the communication controller (5) even during startup of the communication it is suggested, that the bus guardian (6) has a priori knowledge about possible deviations from the communication media access schedule during startup of the communication and that the bus guardian (6) during startup makes use of the a priori knowledge to distinguish between an allowed deviation and a forbidden deviation caused by a failure of the communication controller (5).

摘要： A data processing apparatus receives a communication signal that contains temporally successive bits. A programmable processor circuit executes a plurality of series of programmed instructions for operations such as parity checking, each at a time of reception of a respective one of the bits. The processor circuit suspends operation each time after executing a respective one of the series of instructions. A synchronization circuit triggers execution of respective ones of the series, each time at the time of reception of the respective one of the bits, and, except for a last one of the series, prior to reception of one or more later bits that contribute to the data word.

摘要： A data processing apparatus receives a message containing a sync break interval with a unique bit pattern and a sync field interval identified by the sync break interval. A timing property of the sync field interval specifies the length of bit periods of the message. A clock source circuit supplies a sampling clock signal to define time points for sampling bits from the message. The clock source circuit adapts a frequency of the sampling clock signal to the timing property of the sync field interval. The clock source circuit searches for potential sync break intervals that match the unique bit pattern for a range of bit period values and verifies for each potential sync break interval whether the sync field interval identified by that potential sync break interval specifies a bit period with a duration so that the sync break interval matches the unique pattern for the specified bit period, as a condition prior to supplying the sampling clock signal at the adapted frequency specified by the sync field interval identified by the potential sync break interval. Supply of sampling clock signals is preferably suppressed after an end of a preceding message until said condition is met.

摘要： The invention refers to one of a number of nodes of a communication system. The nodes are connected to a communication media for transmitting data among the nodes. Said one node comprises a communication controller, across which the node is connected to the communication media, and a bus guardian for controlling access of the communication controller to the communication media. In order to provide a cheap but nevertheless reliable way for monitoring the synchronized clock signal of a node of a communication system and in particular for detecting deviations of the synchronized clock signal it is suggested that a synchronized clock signal from the communication controller is made available to the bus guardian, and that the bus guardian comprises means for monitoring the synchronized clock signal using a bus guardian internal clock signal, which is generated by means of an electronic circuit and which is less accurate than the synchronized clock signal to be monitored.

摘要： The communication bus system comprises a plurality of node circuits (10a-d) and a relay circuit (12, 14, 16) coupling the node circuits (10a-d). The relay circuit (12, 14, 16) has a transceiver circuit (124, 164) for relaying messages (21) between the node circuits (10a-d) in a normal mode. The transceiver circuit (124, 164) is powered down in a sleep mode. A detector circuit (120, 160) detects an incoming message (41) when the relay circuit (12, 14, 16) is in a sleep mode. A mode control circuit (122, 162) powers up the transceiver (124, 164) in response to detection of an incoming message (21). Steps are taken that ensure, in the normal mode, that messages (21) will not be relayed in unreadable form. The mode control circuit (122, 162) is arranged to cause the transceiver (124, 164) to relay a remainder (25) of the incoming message (21) after power up. In an embodiment the power needed to transmit the remainder (25) of the message (21) is drained from a capacitor (306) in the power supply (30) before the power supply (30) controls the power supply voltage in the normal mode. In another embodiment the detector circuit (120, 160) temporarily controls the direction of operation of the transceivers (124, 164) at the start of the normal mode instead of further detectors (58a-d) that normally control the direction of operation in the normal mode.
摘要翻译：通信总线系统包括多个节点电路（10a-d）和耦合节点电路（10a-d）的继电器电路（12,14,16）。继电器电路（12,14,16）具有用于以正常模式中继节点电路（10a-d）之间的消息（21）的收发器电路（124,164）。在休眠模式下，收发器电路（124,164）被掉电。当继电器电路（12,14,16）处于睡眠模式时，检测器电路（120,160）检测输入消息（41）。模式控制电路（122,162）响应于输入消息（21）的检测，对收发器（124,164）供电。采取步骤，确保在正常模式下，消息（21）将不会以不可读的形式进行中继。模式控制电路（122,162）被布置成使得收发器（124,164）在上电之后中继输入消息（21）的余数（25）。在一个实施例中，在电源（30）以正常模式控制电源电压之前，将消息（21）的剩余部分（25）所需的功率从电源（30）中的电容器（306）中排出。在另一个实施例中，检测器电路（120,160）在正常模式开始时暂时控制收发器（124,164）的操作方向，而不是通常控制在正常模式下的操作方向的另外的检测器（58a-d）正常模式。
