FUNCTION EXECUTION TIME MEASURING DEVICE, FUNCTION EXECUTION TIME MEASURING METHOD, AND FUNCTION EXECUTION TIME MEASURING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a function execution time measuring device capable of measuring execution time of a function within a specified program only if an operating state satisfies specified conditions.SOLUTION: A function execution time measuring device 1 has: a process-by-process storage area 1b for storing an operating state of a process operating in a processor in a first-in last-out (stack) form; a program loader 2 for loading a preinstalled main storage device with a target program; dynamic patch means 3 for inserting first and second hooks for generating an interrupt at each of a start point of a measuring target function and a start point of a specifying function within a target program; and execution time measuring means 4 for measuring and outputting lapse time from the first hook generating an interrupt to the execution of the measuring target function being completed, if the second hook generates an interrupt.
