Abstract:
A method of reducing power that is dissipated by a device capable of making a transition between a first state and a second state in which said device dissipates less power than in said first state, comprising:computing a predicted amount of power that would be saved by said device if said device makes a transition from said first state to said second state; computing a time at which said device should transition from said first state to said second state, using at least one predicted amount of power to be saved; and, transitioning said device from said first state to said second state, wherein said computing a time at which said device should transition from said first state to said second state further comprises: computing a distribution of past command intervals; computing a response delay time with respect to a next command using said distribution of past command intervals; and, computing a time at which said device should transition from said first state to said second state using said response delay time with respect to the next command.
