Some embodiments of the invention provide a forwarding element that can be configured through in-band data-plane messages from a remote controller that is a physically separate machine from the forwarding element. The forwarding element of some embodiments has data plane circuits that include several configurable message-processing stages, several storage queues, and a data-plane configurator. A set of one or more message-processing stages of the data plane are configured (1) to process configuration messages received by the data plane from the remote controller and (2) to store the configuration messages in a set of one or more storage queues. The data-plane configurator receives the configuration messages stored in the set of storage queues and configures one or more of the configurable message-processing stages based on configuration data in the configuration messages.

A method in a first wireless device (WD) supporting wireless communication with a second WD is described. A plurality of wireless packets is received from the second WD including at least a first wireless packet. At least another wireless packet of the plurality of wireless packets is one of a retry packet and a repeat packet of the first packet. Each wireless packet of the plurality of wireless packets includes a plurality of bits and a first group of bits. For each received wireless packet, the plurality of bits corresponding to the received wireless packet is de-spread, and the first group of bits is correlated with a predetermined group of bits. The method further includes performing a majority vote based on the correlation of the first group of bits of each received wireless packet and creating a corrected packet based in part on the majority vote.

A writing circuit for writing write data into a memory comprises an evaluator configured for providing an error handling code on the basis of the write data. A modifier reversibly modifies extended write data comprising both the write data and the error handling code in dependence on address information related to a writing address in order to provide modified extended write data. A writer writes the modified extended write data in a position of the memory defined by a writing address. A reading circuit for reading extended read data from a memory comprises a reader configured for reading the extended read data from a position of the memory defined by a reading address. A de-modifier modifies the extended read data in dependence on address information related to a reading address in order to provide extracted read data and an extracted error handling code. An error-detector detects based on the extracted error handling code whether the extracted read data comprises an error.

A checksum addition method includes obtaining a command and an address transmitted from a request source; reading data from the address according to the command; calculating a checksum to be added to the data; and transmitting the checksum and the data to the request source, wherein the calculating calculates the checksum in a data unit according to a type of the command.

Disclosed are systems, methods, and non-transitory computer-readable media for a variable multiplexer for vehicle communication bus compatibility. A device includes a variable multiplexer that can be electronically configured to a desired pinout configuration to provide compatibility with multiple vehicles. For example, the variable multiplexer may be electronically configured based on a pinout configuration used by the vehicle to connect pins in the device to the corresponding pins on the data link connector that provide the same specified function. The device may therefore use a single standardized cable with vehicles using a variety of pinout configurations.

An arrangement with an actuator has a transmitting device for transmitting control telegrams with a control command for the actuator. At least two receiving devices receive the control telegrams and generate a control signal for the actuator. A decision device between the receiving devices and the actuator allows the actuator to implement the control signals with a release signal if the control signal is present from all or a minimum number of receiving devices. The transmission device transmits the control command to each receiving device with a receiver-specific control telegram that is provided with a respective control instruction that indicates the continuous telegram number of the respective transmitted control telegram in encrypted or non-encrypted form. The receiving devices accept a control telegram as valid if the control instruction indicates a telegram number that is expected by the receiver. The control signal is generated if the control telegram is valid.

A decoding apparatus and method. When all the code words in the to-be-decoded group meet that a checksum is 0, forward error correction (FEC) decoding is not performed, and only the sign bit decision is performed. That is, in a process of performing multiple times of decoding on each code word, FEC decoding is not always performed every time. This reduces power consumption required by FEC decoding.

The current invention relates to an encoder for converting a set of data words into a data block having a header section, a checksum section and a payload section; the encoder comprising: a header inserter arranged to insert a header pattern in the data block; a checksum calculator arranged to calculate a checksum of the set of data words; a data word converter arranged to convert the set of data words into a set of obfuscated data words being a result of applying an exclusive or operation between the set of data words and the checksum.
