Abstract: PROBLEM TO BE SOLVED: To provide a method and a system for decreasing complexity related to the test and utilization of a multicore central processing unit(CPU). SOLUTION: A data processing system 100 is provided with at least one CPU 110 provided with first and second processing cores 160A and 160B at least. Besides, the data processing system 100 is provided with input devices 162A and 162B for receiving control input for specifying which processing core is to be used. Further, the data processing system 100 is provided with a configuration logic for comprising the data processing system by making at least one processing core active and making all or at least one processing core inactive corresponding to the control input in response to the reception of the control input.
