| 20080207278 | Mobile platform tracking in wireless networks - A mobile station in a wireless network provides a presence indication when in a power saving state. The presence indication is sent periodically, and the period is dependent on whether the mobile station is stationary or in motion. The period may also be dependent on an asset protection level of the mobile station. | 08-28-2008 |
| 20100077243 | CONSERVING POWER IN A COMPUTER SYSTEM - A power management unit (PMU) may determine an optimal power saving state using a break-even period of a power saving state and an expected idle duration based on a first policy. The PMU may determine the optimal power saving state using a first break even period and actual idle duration based on a second policy. The break-even period may equal a minimum time a computer system should remain in a power saving state to compensate for the power consumed by the system to enter and exit that power saving state. The expected idle time duration is determined as an average of idle duration and a recent sample of idle duration. The actual idle duration is the difference of a first and second time point that represents entry and exit points to and from the power saving state. The PMU may transition the system to the optimal power saving state. | 03-25-2010 |
| 20100153590 | DMA (DIRECT MEMORY ACCESS) COALESCING - In general, in one aspect, a method includes determining a repeated, periodic DMA (Direct Memory Access) coalescing interval based, at least in part, on a power sleep state of a host platform. The method also includes buffering data received at the device in a FIFO (First-In-First-Out) queue during the interval and DMA-ing the data enqueued in the FIFO to a memory external to the device after expiration of the repeated, periodic DMA coalescing interval. | 06-17-2010 |
| 20100332869 | Method and apparatus for performing energy-efficient network packet processing in a multi processor core system - A method and apparatus for managing core affinity for network packet processing is provided. Low-power idle state of a plurality of processing units in a system including the plurality of processing units is monitored. Network packet processing is dynamically reassigned to processing units that are in a non-low power idle state to increase the low-power idle state residency for processing units that are in a low-power idle state resulting in reduced energy consumption. | 12-30-2010 |
