INCORPORATED SYSTEM, AND POWER SAVING CONTROL METHOD IN INCORPORATED SYSTEM

摘要

PPROBLEM TO BE SOLVED: To achieve power saving in an incorporated system by setting a clock frequency of a CPU to a necessary minimum value even when a plurality of applications overlap to use hardware resources. PSOLUTION: This power saving control method in the incorporated system defines hardware resources to be used in each application belonging to the incorporated system, defines weighted values to be a reference value of a clock frequency required to operate the hardware resources in each of the hardware resources, and sets a clock frequency of the incorporated system on the basis of the largest weighted value among the weighted values of the hardware resources used by the active application.
