Non-virtualized devices are shared * using a parameterized Resource interface, and are powered down according * to some policy whenever there are no more pending requests to that Resource. * The policy implemented by this component is to delay the power down of a * device by some contant factor.  Such a policy is useful whenever a device * has a long wake-up latency.  The cost of waiting for the device to power * up can be avoided if the device is requested again before some predetermined * amount of time.<br><br> * * Powerdown of the device is done through the <code>StdControl</code> * interface, so this component can only be used with those devices that * provide that interface.<br><br> * * For devices providing either the <code>AsyncStdControl</code> or * <code>SplitControl</code> interfaces, please use either the * <code>AsyncStdControPowerManagerC</code> component or the * <code>SplitControlPowerManagerC</code> component respectively. *  * @author Kevin Klues (klueska@cs.wustl.edu) * @see  Please refer to TEP 115 for more information about this component and its *          intended use. */ generic configuration StdControlPowerManagerC(){  provides {    interface Init;  }  uses {    interface StdControl;    interface PowerDownCleanup;    interface Init as ArbiterInit;    interface ResourceController;  }}implementation {  components new PowerManagerP() as PowerManager;  Init = PowerManager;   PowerManager.StdControl = StdControl;  PowerManager.PowerDownCleanup = PowerDownCleanup;   PowerManager.ArbiterInit  = ArbiterInit;  PowerManager.ResourceController = ResourceController;}
