  • Patent number: 8897352
    Abstract: A method comprises performing a first pass test over a plurality of sets of equalization coefficients to filter the plurality of sets of equalization coefficients to produce one or more filtered sets of equalization coefficients. Each filtered set of equalization coefficients meets a first predetermined threshold. The method also comprises performing a second pass test over the one or more filtered sets of equalization coefficients to determine a final set of equalization coefficients that meets a second predetermined threshold. The second pass test produces more accurate results than the first pass test.

  • Publication number: 20140173148
    Abstract: A starvation control engine operable to monitor data transactions within a computer system potentially prevents or corrects starvation issues. The starvation control engine is programmed to generate one or more bubbles in a data path based on one or more trigger events. The trigger events or the criteria underlying the trigger events may be programmed or changed by at least one of a user or the starvation control engine. The starvation control engine determines when, for how long, and how often to generate the one or more bubbles based on the type of event.

  • Patent number: 6938176
    Abstract: A graphics processing device implementing a set of techniques for power management, preferably at both a subsystem level and a device level, and preferably including peak power management, a system including a graphics processing device that implements such a set of techniques for power management, and the power management methods performed by such a device or system. In preferred embodiments, the device includes at least two subsystems and hardware mechanisms that automatically seek the lowest power state for the device that does not impact performance of the device or of a system that includes the device. Preferably, the device includes a control unit operable in any selected one of multiple power management modes, and system software can intervene to cause the control unit to operate in any of these modes.

  • Publication number: 20040155854
    Abstract: Embodiments of the present invention generally provide methods, apparatus, systems, and articles of manufacture for gradually dimming backlit displays. The backlit displays may be gradually dimmed by reducing a level of the backlighting from an initial level to a final level in a plurality of steps over a dimming interval. The gradual dimming operations may be performed by any suitable combination of software and hardware components. For some embodiments, parameters used for the dimming, such as the dimming interval and final level of the backlighting, may be specified by a user.
