<p><P>PROBLEM TO BE SOLVED: To allow a semiconductor device having a plurality of modules to exhibit the appropriate performance of each module, while managing power on the basis of distributed management, and managing the power permitted for a chip as a whole. <P>SOLUTION: A predetermined power consumption value is defined for each module. The predetermined power consumption value is an amount defined, while the permissible power values of the plurality of modules are taken into consideration. Each of the modules reports the difference between the predetermined power consumption value and the value of actually consumed power to other modules as the amount of extra power. Each of the modules can process data for an amount below the predetermined power consumption value, even without using the extra power coming from the other modules, so as to avoid deadlock. When the amount of extra power is reported from the other modules, the amount of power equal to the predetermined power consumption value and the amount of extra power are set as the amount of power consumable for data processing. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
