A computing device, in particular, for a control unit of a motor vehicle. The computing device is configured to receive messages from at least one external unit. The computing device is configured to store the received messages at least temporarily and to transmit a plurality of the received messages to a cryptographic module, which is configured to execute a check of the transmitted messages.

Efficient distribution of processes between a vehicle control computing device and a cryptographic module, and method for operation thereof

The invention refers to a method and a communication system for transmitting in either direction data between any two devices in a client layer and/or a transport layer of a communication system. The data transmission is performed according to the transport control protocol, referred to hereinafter as TCP. In order to achieve a high data transmission rate it is suggested that central storage means () for buffering the data to be transmitted and a TCP protocol operation block () are provided within the communication system, wherein the TCP protocol operation block () handles references on the transported data stored in the storage means () instead of the data itself. The invention also refers to an embedded acquisition device () located between the two devices of the communication system, between which the data is to be transmitted. The acquisition device () comprises means adapted for performing the method according to the present invention.

Distributed measurement arrangement for an embedded automotive acquisition device with TCP acceleration

An interface unit is provided for the arrangement between a bus system, to which a processor unit and a data memory are connectable, and a data transporting unit, in particular a network processor, are described. The interface unit carries out a direct memory access to the data memory as a function of an identifier (chid) previously agreed upon between an application and the data transporting unit.
