Abstract: A system and method of compensating for effects of on-chip processing variation on an integrated circuit. The integrated circuit is divided into a set of regions. Then, a region control logic, included in each region, predicts a processing variation in each respective region of the integrated circuit. Finally, each region control logic automatically selects one of a set of available power settings to power each one of the respective regions, in response to the region control logic predicting the processing variation, wherein the processing variation of each of the set of regions is minimized.

Abstract: An apparatus and method of reducing power consumption in a station on a wireless LAN is provided. Included is a cumulative lead time frame receiver, a self lead time frame production transmission unit, an inactive state cumulative lead time count unit, and an active state converter. When a predetermined station is in an active state, the cumulative lead time frame receiver receives a cumulative lead time frame including a cumulative lead time value from a coordinator. If the cumulative lead time value included in the cumulative lead time frame received by the cumulative lead time frame receiver is effective, the inactive state cumulative lead time count unit converts the active state of the predetermined station into an inactive state, in which less power is consumed. If the inactive state cumulative lead time count unit completes counting, the active state converter converts the inactive state into the active state.

Abstract: A method is disclosed to selectively provide power to a component disposed in an information storage and retrieval system. Applicants' method supplies a controller comprising a control portion in combination with a plurality of components comprising one or more host adapters, one or more device adapter ports, and a Fibre Channel switch. The method monitors the performance of each of those components. The method discontinues the supply of power to first component while continuing to provide power to the remaining plurality of components. The method then resumes providing power to the first component while continuing the supply of power to the remaining plurality of components.

Abstract: A power monitoring circuit having an automatic feedback function and an overload protection function is described. The power monitoring circuit has a current detection module, a voltage detection module, a multiplication module, and an overload protection module. The current detection module is used to obtain the current value of a power supply path. The voltage detection module is used to obtain the voltage value of the power supply path. The multiplication module generates the power value of the power supply path with reference to the current value and the voltage value. The overload protection module determines, with reference to the power value, whether to switch off the input of the power supply path, so that the overload protection module protects the system load connected to the power supply path. The current detection module, the voltage detection module, and the multiplication module are integrated into a chip.

Abstract: A novel personal electronic device includes a first (embedded) and second (non-embedded) processors including associated operating systems and functions. In one aspect, the first processor performs relatively limited functions, while the second processor performs relatively broader functions under control of the first processor. Often the second processor requires more power than the first processor and is selectively operated by the first processor to minimize overall power consumption. Protocols for functions to be performed by the second processor may be provided directly to the second processor and processed by the second processor. In another aspect, a display controller is designed to interface with both processors. In another aspect, the operating systems work with one another. In another aspect, the first processor employs a thermal control program. Advantages of the invention include a broad array of functions performed by a relatively small personal electronics device.
