Abstract

A granularity information acquiring unit acquires information on granularity assigned to each core. A structure information creating unit calculates frequency of appearance for each task or for each function included in the task based on the granularity information, and creates information on the frequency. A dependence information creating unit creates information on dependence on other tasks or other functions for each task or for each function included in the task based on the granularity information. An output unit outputs each of above information.

Claims
