The Intel® Core™ Duo processor-based technology introduces the enhanced power management-aware processor including CPU-based power management actions such as dynamic L2 resizing. Dynamically resizing/shutting down of the L2 cache is needed in preparation for DeepC4 state in order to achieve lower voltage idle state for saving power. As described in this paper, efficient multi-threading provides optimal performance scaling as well as power savings. Multimedia applications reduce/shutdown interrupts after content delivery to save power.
