the present invention relates to a methodology for controlling the power consumption in a computing device based upon extended register file extension values , the method further comprising the steps of identifying an upper bit data register value and a lower bit data register value for a data register value , and inputting the upper bit data register value to a detect logic component , wherein the upper bit data register value is used to generate a data register extension value . the method further comprises the steps of utilizing the data register extension value as a power control signal serving to activate or deactivate a power supply signal to a segment of a data path , and updating the data register extension value in a subsequent data register write computational function .
