ABSTRACT:
Improved operation of multi-processor chips is achieved by dynamically controlling processing load of chips and controlling, significantly greater than on/off granularity, the operating voltages of those chips so as to minimize overall power consumption. A controller in a multi-processor chip allocates tasks to the individual processors to equalize processing load among the chips, then the controller lowers the clock frequency on the chip to as low a level as possible while assuring proper operation, and finally reduces the supply voltage. Further improvement is possible by controlling the supply voltage of individual processing elements within the multi-processor chip, as well as controlling the supply voltage of other elements in the system within which the multi-processor chip operates.
