Abstract
A multi-processor control device according to an example of the invention comprises a cooperative control unit which determines priorities of requests issued from processors to a shared resource which are used to suppress a total power consumption of the processors within a range in which performance constraints of programs executed by the processors are satisfied, and determines a frequency of each of the processors so as to suppress the total power consumption within the range in which the performance constraint of the each program is satisfied, a first control unit which issues requests from the processors to the shared resource in accordance with priorities determined by the cooperative control unit, and a second control unit which controls the frequency of each of the processors in accordance with the frequency determined by the cooperative control unit.
