DATA PROCESSING DEVICE

摘要

A communication unit (104) receives output data, that is, data to be sent from a BCM (111) to I/O devices (121-123), from the BCM (111). A shared memory (102) stores the output data received by the communication unit (104). An anomaly detection communication processing unit (105) and the communication unit (104) generate a communication frame for anomaly detection which is used to request the BCM (111) to transmit the output data held therein. The communication unit (104) transmits the communication frame for anomaly detection to the BCM (111) and receives the output data held by the BCM (111) from the BCM (111) as a response to the communication frame for anomaly detection. An anomaly detection determination unit (106) compares the output data received from the BCM (111) with the output data stored in the shared memory (102).
