MULTIPROCESSOR SYSTEM, INTERRUPT CONTROL METHOD, AND INTERRUPT CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To increase the number of sleeping processors to reduce the power consumption of the processors.SOLUTION: When an interrupt is applied to any of a plurality of processors 3, an interrupt controller 2 predicts the operation rate of each processor 3 when the interrupt is applied. The interrupt controller 2 controls to apply an interrupt to the processor 3 whose operation rate is closest to an upper limit operation rate and does not exceed the upper limit operation rate, among the predicted operation rates of the processors 3.
