EVALUATING DEVICE FOR PROGRAM PERFORMANCE

PURPOSE: To determine more accurately the processing time of a task to start processing by plural pieces of input. CONSTITUTION: An event generating time processing part 11, when detecting a time when an event is inputted to buffers 23, 24 and 26, outputs time data to a storage processing part 13 with a decision value from a decision counter 12. The storage processing part 13 stores the time when the event is inputted in the buffers 23, 24 and 26 in a file, respectively by making correspond to the decision value of the decision counter 12. A calculation processing part 15 calculates the processing time of the task 29 absorbing difference between the generating time of the event 21 and that of the event 22 based on data stored in the file 14 at every decision value, and outputs it to a display operation processing part 16. The display operation processing part 16 displays the calculation result of the calculation processing part 15 on terminal equipment 2.
