International Classification:

US Classification:

711163, 711E12001

Abstract:

An information handling system includes a processor with an array power management controller. The array power management controller gates off a memory array, such as a cache, to conserve power whenever a group of instructions in a branch instruction queue together as a group exhibits a confidence in the accuracy of branch predictions of branch instructions therein that is less than a first predetermined threshold confidence threshold. In one embodiment of the information handling system, the array power management controller speculatively inhibits the gating off of the memory array when confidence in the accuracy of a branch prediction for a particular currently issued branch instruction exhibits less than a second predetermined threshold confidence threshold. In this manner, the array power management controller again allows access to the memory array in the event a branch redirect is likely.

Abstract:

An information handling system includes a processor that throttles an instruction fetcher whenever a group of instructions in a branch instruction queue together exhibits a confidence in the accuracy of branch predictions of branch instructions therein that is less than a first predetermined threshold confidence threshold. In one embodiment, the processor includes a fetch throttle controller that inhibits fetch throttling by the instruction fetcher when confidence in the accuracy of a branch prediction for a particular currently issued branch instruction exhibits less than a second predetermined threshold confidence threshold.

International Classification:

G06F 9/32

US Classification:

712205, 712239

Abstract:

An information handling system employs a processor that includes a thread priority controller. An issue unit in the processor sends branch issue information to the thread priority controller when a branch instruction of an instruction thread issues. In one embodiment, if the branch issue information indicates low confidence in a branch prediction for the branch instruction, the thread priority controller speculatively increases or boosts the priority of the instruction thread containing this low confidence branch instruction. In the manner, should a branch redirect actually occur due to a mispredict, a fetcher is ready to access a redirect address in a memory array sooner than would otherwise be possible.

International Classification:

US Classification:

356487000, 356491000, 356477000

Abstract:

A polarization control system includes a light source that generates two light beams with different polarization states and optical frequencies. A polarization state modulator changes the polarization states of the two light beams. A first detector path generates a first beat signal from the two light beams passing through a first polarizer. A second detector path generates a second beat signal from the two light beams passing through a second polarizer that is oriented substantially orthogonal to the first polarizer. An amplitude detector generates an amplitude beat signal from the first and the second beat signals. The system then uses the amplitude beat signal to determine how to adjust the polarization state modulator in order to generate the first and the second light beams with the desired polarization states.

International Classification:

US Classification:

712239, 712E09016

Abstract:

An information handling system employs a processor that includes a thread priority controller. The processor includes a memory array that stores instruction threads including branch instructions. A branch unit in the processor sends flush information to the thread priority controller when a particular branch instruction in a particular instruction thread requires a flush operation. The flush information may indicate the correctness of incorrectness of a branch prediction for the particular branch instruction and thus the necessity of a flush operation. The flush information may also include a thread ID of the particular thread. If the flush information for the particular branch instruction of the particular thread indicates that a flush operation is necessary, the thread priority controller in response speculatively increases or boosts the priority of the particular instruction thread including the particular branch instruction. In this manner, a fetcher in the processor obtains ready access to the particular thread in the memory array.

International Classification:

US Classification:

Abstract:

The invention provides a herbal cellulite treatment employing, in preferred embodiments, topical treatments, both method and cosmetic composition, wherein a refined lipophilic extract, and preferably also a refined aqueous extract of a Malvaceae plant, preferably whole Hibiscus Abelmoschus, are applied to the skin overlying cellulite-afflicted tissues. The treatments are intended to last at least four, and preferably eight or more weeks. Clinical tests show suprisingly superior results to those obtainable with aminophylline compositions. Inventive treatments can reduce thigh diameters and fatty layer thickness, as well as skin condition. In vitro tests show remarkable lipolytic properties, apparently attributable to. beta. -receptor stimulation, and valuable lipogenesis inhibition properties apparently attributable to. alpha. sub. 2 -blocking.
