摘要
In the clock control of the present invention, CPU usage rate is calculated for each of a plurality of applications with respect to a maximum clock frequency attainable by the information processing apparatus, based on registered clock frequency necessary for executing each of the applications, and a system clock frequency determined by a total sum of the CPU usage rates is set in the apparatus. If the frequency with which this system clock frequency exceeds the maximum clock frequency increases, an apparatus upgrade necessity alarm is sent. Also, any one clock frequency from among a comfortable operation clock frequency for the application, a minimum clock frequency for the application to run, and a permissible system clock frequency corresponding to usage environmental conditions (power source state, temperature and noise) is set according to the usage environmental conditions. Thereby, optimum performance of the apparatus can be provided.
