Method and apparatus of the present invention include an image-capturing device coupled to a computer system. An image captured by the image-capturing device is analyzed using a face tracking technique to learn behaviors of the user. This may include determining if the user is paying attention. The attention may be toward a display of the computer system. When the user does not pay attention, power consumption of one or more components of the computer system is reduced.

Method and apparatus for monitoring human attention in dynamic power management

Method and Apparatus of the present invention provides innovative real-time system power management with respect to user presence by using an image-capturing device and computer vision technology. The image-capturing device is to capture an image that includes an area in front of a computer system. The image is to be analyzed to determine the user presence. When it is determined that the user is not present, one or more components of the computer system is placed in a power saving mode.

Method and apparatus for adaptive realtime system power state control

A computer is power managed by detecting the presence of a user. A camera is associated with the computer and the output from the camera is analyzed to determine if the user is present. If the user is present, then the computer is maintained in its non-power manage state. When the user leaves, however, the user's presence is no longer detected by the camera, and the power managed state can be quickly entered.

Method and apparatus for real time monitoring of user presence to prolong a portable computer battery operation time

A computer system that optimizes the power efficiency of a portable computer system is described. Specifically, the secondary memory of the system is partitioned. A standard hard disk drive is used to store lower utilization applications, while a micro storage unit is used to store high utilization applications.

Tiered secondary memory architecture to reduce power consumption in a portable computer system

In accordance with one embodiment, the invention provides a method comprising monitoring a power consumption of a processor in executing a program while running in a speculative execution mode wherein instructions are speculatively executed; and turning off said speculative execution mode if said power consumption is above a predetermined threshold. According to another embodiment the invention provides a processor comprising a speculative mode wherein instructions are speculatively executed; a non-speculative execution mode wherein instructions are executed non-speculatively; and a speculation control mechanism to selectively cause said processor to operate in said non-speculative mode based on a power consumption criterion.

Method and apparatus for controlling execution of speculations in a processor based on monitoring power consumption

A computer is power managed by detecting the presence of a user. A camera is associated with the computer and the output from the camera is analyzed to determine if the user is present. If the user is present, then the computer is maintained in its non-power manage state. When the user leaves, however, the user's presence is no longer detected by the camera,and the power managed state can be quickly entered.

A circuit for executing a logical majority operation in a computing system. The logical majority operation operates on multiple operands to determine the majority value of the operands. The circuit of the present invention includes circuitry for receiving multiple operands, logic for executing a logical majority operation in one clock cycle and circuitry for outputting a result of the logical majority operation.
