<P>PROBLEM TO BE SOLVED: To implement a communication control function using limited hardware resources without impairing its expandability and processing performance. <P>SOLUTION: In an electronic control unit connected to a network bus, a function reconfiguration module (114), for which a data processing function corresponding to function definition data written by a central processing unit (110) is set, has a transmission data processing part that comprises: an input data determination part (121) for determining a data ID of transmission data which is sequentially generated and supplied through data processing of the central processing unit; a plurality of transmission packet generation parts (122) for receiving transmission data corresponding to a data ID determination result obtained from the input data determination part and configuring a packet for each transmission target; a sequence control part (123) for outputting the packet by controlling the transmission sequence of packets generated by the transmission packet generation part; and a packet transfer part (124) for providing the packet, which is output from the sequence control part, for an external interface circuit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
