<P>PROBLEM TO BE SOLVED: To improve performance in a data processing device, method and program. Ž<P>SOLUTION: The data processing device including a plurality of processor cores includes: a detection part in which a first processor core detects processing to the first processor core; a determination part which determines whether the detected processing can be executed in a second processor core by use of information stored in a local memory of the second processor core; a first processing time calculation part which calculates a first processing time required to execute the detected processing in the first processor core; a second processing time calculation part which calculates a second processing time required to execute the detected processing in the second processor core after determining whether to add a reading time for causing the local memory to read information based on the determination result of the determination part; a comparison part which compares the first processing time with the second processing time; and a selection part which selects the first processor core or the second processor core to execute the detected processing based on the comparison result.
