PROBLEM TO BE SOLVED: To acquire information related with the behavior of a specific program without stopping the correction or execution of a program with respect to a program under execution in an OS environment. SOLUTION: In a performance profiling acquisition tool 120, the process ID of a measurement object process is registered in an event context register 102 of a processor 100. Then, when a measurement object program 111 is executed under the environment of an OS 110, the process ID of the measurement object program 111 under execution is recorded in a context register 103 of the processor 100 as execution information. The process ID recorded in the context register 103 is compared with the measurement object process ID registered in the event context register 102 by a comparator 104. The comparator 104 outputs a count instruction to an event counter 105 only when the compared process IDs are matched with each other. COPYRIGHT: (C)2010,JPO&INPIT |
