Data processing device and program

When a fixed-cycle send timing arrives, a fixed-period communication processing unit (102) sends data in a shared memory (101) to a BCM (200). An event table storage unit (104) stores an event table that indicates: a condition of data to be sent by an event communication processing unit (106); and a permitted delay time, which is the amount of time permitted starting from when the data satisfying the condition is extracted, until said data is sent. An event detection unit (105) extracts the data in the shared memory (101) satisfying the condition indicated by the event table. To the BCM (200), the event communication processing unit (106) sends the data extracted by the event detection unit (105), before the arrival of the send timing of the fixed-period communication processing unit (102), and by the timing at which the permitted delay time elapses from the time of the data extraction by the event detection unit (105).
