Abstract: Devices and methods for cache prefetching are provided. A device is provided which comprises a quality of service (QOS) component having first assigned registers used to store data to execute a program, a plurality of non-QOS components having second assigned registers used to store data to execute the program and a power management controller, in communication with the QOS component and the non-QOS components. The power management controller is configured to issue fences for the non-QOS components when it is determined that one or more of the non-QOS components are idle, issue a fence for the QOS component when the fences for the non-QOS components are completed and enter a reduced power state when the fences for the non-QOS components and the fence for the QOS component are completed.

Abstract: An article of footwear that includes a photoreactive composition capable of reversibly changing color when contacted with ultraviolet light is provided. The photoreactive composition is incorporated into a panel member that is secured to the article of footwear. For example, in one embodiment, a photoreactive composition, which is initially optically transparent, is contacted with ultraviolet light so that it changes to one or more visible colors (e.g., violet, blue, red, orange, yellow, etc.) during exposure, and then returns substantially to its original color in the absence of ultraviolet light. Likewise, in another embodiment, a photoreactive composition, which initially has one or more visible colors, is contacted with ultraviolet light so that it changes to one or more different visible colors.
