Abstract:
A power consumption control apparatus in a multiprocessor system having a plurality of processors, comprising:a load monitoring means of monitoring any drop or rise in the loads on said processors, and a processor degenerating/adding means for degenerating part of said plurality of processors when a drop in load is detected by said load monitoring means and suspending the supply of power to the degenerated processor(s) and, when a rise in load is detected, resuming the supply of power to the degenerated processor(s) to add the processor(s) to said multiprocessor system wherein: said load monitoring means is provided with: a first detecting means for detecting a drop in the loads on said processors by the lapse of a first fixed length of time; a second detecting means for detecting a rise in the loads on said processors by the lapse of a second fixed length of time; and an interruption generating means for generating interruption to said processors when either said first detecting means or said second detecting means detects either a drop or a rise in load.
