摘要: A system and method for dynamic function based power control is disclosed. In one embodiment, a includes bridge unit having memory controller communication hub coupled to the controller. The further management unit, wherein configured clock-gate responsive determining that each of plurality processor cores are in an idle state I/O interface has been amount time exceeding first threshold. clock-gating low state. may also perform power-gating functional units subsequent same.
