<P>PROBLEM TO BE SOLVED: To provide an electronic control apparatus which makes it possible to suppress a load imposed on a CPU in a situation where the CPU performs processing for controlling a control object apparatus. <P>SOLUTION: A communication frame used in communication between ECSs is prescribed so as to add an identifier (a command ID, a control ID) for identifying types of a message to received data (command data, control value data) and the identifier and the received data are stored in a message box in the ECU. In the ECU, a DMA controller transfers the receive data in the message box to a prepared sectioned RAM storage region (a receiving queue 26, a receiving buffer 27) based on the identifier. This writes the received data in a storage region determined for each type of a message in the RAM and makes it possible to relatively easily perform read-out of a message required when a CPU calculates control amount. <P>COPYRIGHT: (C)2012,JPO&INPIT |
