PROBLEM TO BE SOLVED: To suppress a processing time in the optimal microarchitecture search.SOLUTION: A vicinity searching part 12 evaluates the power/performance of each changed microarchitecture to be obtained by increasing/decreasing the value of one component of a current microarchitecture, and obtains a first search result. A combination creation part 13 creates a list in which the changes of components belonging to each group other than the group of the changed components of the changed microarchitecture are combined. A power/performance simple calculation part 14 calculates the temporary power/performance evaluation of each combination of the list on the basis of the variation of evaluation with respect to constitution when the change of the components is single change, and obtains a second search result. A next search object selection part 15 selects the microarchitecture of the next successive search from the search result, and a power/performance re-evaluation part 16 evaluates the power/performance of the microarchitecture when the selection is performed from the second search result, and sets the selected microarchitecture as the current microarchitecture in the next successive search when the evaluation value is within an allowable range. |
