MULTIPROCESSOR CONTROL DEVICE AND ITS CONTROL METHOD |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To suppress at least either the power consumption or energy consumption in a whole multi-processor. <P>SOLUTION: This multi-processor control device is configured to determine "the priority of a request to be issued from processors PU<SB>0</SB>to PU<SB>n</SB>to a shared resource" for suppressing at least one of the total power consumption and total energy consumption of the processors PU<SB>0</SB>to PU<SB>n</SB>in a range satisfying the performance constraint of each program to be executed by the processors PU<SB>0</SB>to PU<SB>n</SB>, and determine "at least one of the frequency and power supply voltage of the processors PU<SB>0</SB>to PU<SB>n</SB>" for suppressing at least one of the total power consumption and total energy consumption in a range satisfying the performance constraint of each program. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
