Other embodiments may be described. | 10-02-2008 |
| 20090006658 | Deferring peripheral traffic with sideband control - In some embodiments, a system comprises a USB host system comprising a USB function driver, and a USB device coupled to the USB host system via a USB interface, wherein the USB device cooperate to defer one or more data traffic exchanges by passing control messages via a sideband communication link. Other embodiments may be described. | 01-01-2009 |
| 20090006704 | Deferring Peripheral traffic with sideband control - In some embodiments, a system comprises a host system comprising an industry standard interface, a peripheral device coupled to the host device via the industry standard interface, and logic in the host system to confirm that the host device supports an enhanced feature, identify at least one pin on the industry standard interface on which the enhanced feature may be implemented, enable support for the enhanced feature on the at least one pin, and route communication traffic associated with the enhanced feature to the at least one pin. Other embodiments may be described. | 01-01-2009 |
| 20090172434 | Latency based platform coordination - In some embodiments, an electronic apparatus comprises at least one processor, a plurality of components, and a policy engine comprising logic to receive latency data from one or more components in the electronic device, compute a minimum latency tolerance value from the latency data, and determine a power management policy from the minimum latency tolerance value. | 07-02-2009 |
| 20110078473 | LATENCY BASED PLATFORM COORDINATION - In some embodiments, an electronic apparatus comprises at least one processor, a plurality of components, and a policy engine comprising logic to receive latency data from one or more components in the electronic device, compute a minimum latency tolerance value from the latency data, and determine a power management policy from the minimum latency tolerance value. | 03-31-2011 |

| 20080288798 | Power management of low power link states - A method and apparatus for intelligent power management for low power link states. Some embodiments include methods, apparatuses, and systems for a device coupled to a controller via a link; a link power management engine to alter a power state of the link based on a transaction and some knowledge of future transactions between the device and the controller; and a memory or logic to store the link power management engine. In some embodiments, the memory stores information about at least one of the following: the power state of the link, the device buffering, the controller or device state or a history of transactions. In some embodiments, the device is a peripheral of a computer system. In some embodiments, the method may include transitioning the device to various link states. Other embodiments are described. | 11-20-2008 |
| 20100169684 | DOWNSTREAM DEVICE SERVICE LATENCY REPORTING FOR POWER MANAGEMENT - For one disclosed embodiment, a transition from a first state to a second, different state for at least a portion of a downstream device may be identified. The first and second states may correspond to different levels relating to activity for at least a portion of the downstream device. Data corresponding to a service latency may be transmitted to an upstream device in response to the identified transition for one or more upstream devices to manage power based at least in part on the service latency. Other embodiments are also disclosed. | 07-01-2010 |
| 20100169685 | IDLE DURATION REPORTING FOR POWER MANAGEMENT - For one disclosed embodiment, data corresponding to an idle duration for one or more downstream devices may be received. Power may be managed based at least in part on the received data. Other embodiments are also disclosed. | 07-01-2010 |
