    摘要: In a method for operating a communication system having a plurality of nodes which have access to a shared channel, a transmission process for transmitting a message via the channel is monitored for bit errors, and when a bit error occurs, a signaling message is transmitted via the channel in order to signal the bit error. In order to allow communications processes between the nodes to be controlled as a function of a bit error rate of the channel, a signaling rate of the signaling messages is measured and a bit error rate of the channel is determined as a function of the signaling rate.

    摘要: A memory protection unit includes at least a first access control unit and a second access control unit programmed for controlling an access to a memory device. Further a method to operate a processing system comprising multiple processing devices and multiple memory protection units associated to the multiple processing devices. The access to the memory by a processing device is approved if first access control unit and second access control unit of the memory protection associated to the processing device approves the access and access is rejected if first access control unit or second access control unit rejects the access. The first access control unit is programmable by the associated processing device alone and the programming of the second access control unit is readable by an additional processing device which is to be used in a system with multiple programming devices, not the associate processing device.

    摘要: The invention relates to a cyclical time-based communication system, for the transmission of useful data (DATA) between users of the system, which comprises a databus and users connected thereto. The data transmission occurs within cyclical repeating timeframes, each with at least two timeslots. Each timeslot is provided for the transmission of a message (Ni). A message (Ni) comprises at least part of the useful data (DATA) and each message (Ni) is provided with a code (ID). The bandwidth available for data transmission may be better utilized, if the code (ID) is placed within the message (Ni) as a part thereof, each message (Ni) is additionally provided with time information concerning the timeslot which may be extracted from the code and at least one of the timeslots within the timeframes may be used for transmission of various messages in various cycles. In a preferred embodiment the information relating to the current cycle comprises an ordinal number for the cycle. In the simplest case the number has two values 0 and 1. Even and odd cycles can thus be differentiated. The ordinal number may be increased to differentiate more cycles from each other. The transmission method is preferably based on the FlexRay protocol.
