INFORMATION PROCESSOR, PROCESSING METHOD AND PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an information processor capable of precisely calculating execution time.SOLUTION: The information processor includes: a totalization part 23 that counts execution ratio information of plural functions included in a program to be analyzed based on plural pieces of branch information included in the program to be analyzed; and an analysis section 24 that calculates appearance interval of the functions by using the execution ratio information of the functions counted by the totalization part 23 on plural pieces of branching information sampled by the branch trace support function 26 to analyze the sampling time of the functions based on the sampling start time when the sampling of the plural piece of branch information has started and the calculated appearance intervals of the functions.
