PROBLEM TO BE SOLVED: To solve the problem that it is difficult to obtain correlation between trace information of a CPU (central processing unit) and performance statistical information of a performance monitor.SOLUTION: The data processor has a measurement trigger 201 shared by a CPU trace part 300 and a performance monitor part 400. The CPU trace part 300 generates an event packet, and inserts the event packet into a CPU trace. Simultaneously therewith, the performance monitor part 400 reads a snapshot of measurement data of a performance counter 410, copies it to a buffer 420, sequentially packetizes it, and outputs it. Thereby, a measurement period is indicated by the event packet in the CPU trace, and the CPU trace can be easily correlated with statistical data of the performance monitor. |
