<p>PROBLEM TO BE SOLVED: To measure execution times by tasks and accurately find the use rate of a CPU even when the operation clock of the CPU is changed. SOLUTION: This instrument has the CPU 1 which executes tasks identified with IDs, an execution-time-by-task storage part 6 having a storage area wherein the execution times by the tasks can be stored by the IDs, a clock generation part 4 which generates reference clock pulses for measurement when the execution times of the respective tasks are measured, and a totalizing means 5 which totalizes the execution times of the tasks within a certain time calculated from the reference clock pulses for measurement by the storage areas of the storage part 6.</p> |
