摘要： A method and apparatus utilizes a three dimensional rendering engine to rotate an image based on user selected or otherwise determined screen orientation. A vertex coordinate transformation is defined for a rotated destination image. The source image is used as a texture for texture mapping during rendering operation to produce rotated image. In one embodiment, a separate set of software instructions is used for each orientation mode. Accordingly, a non-pixel by pixel based 3D rotation may be carried out using a 3D rendering engine to avoid a single parameter based seriatim pixel by pixel based orientation.

摘要： An adaptive temperature dependent clock feedback control system and method for adaptively varying a frequency of a clock signal to a circuit such that the circuit may operate at a maximum safe operating clock frequency based on a circuit junction temperature. The clock control system includes a thermal sensor and a temperature dependent dynamic overclock generator circuit. The thermal sensor detects a junction temperature corresponding to at least a portion of the circuit on a semiconductor die. The temperature dependent dynamic overclock generator circuit varies the clock signal based on the semiconductor die junction temperature, such that the clock signal operates at the highest possible operating frequency associated with the detected junction temperature. The frequency of the clock signal is increased from a first frequency to at least a second frequency and a third frequency if the junction temperature is below a lower junction temperature threshold.

摘要： In a power management scheme for a power-consuming (e.g. electronic) device, one of multiple predefined operating parameter sets is selected. Each of the sets comprises multiple operating parameter values for the device. Examples of operating parameters include clock frequency or voltage for example. The selection may be responsive to the detection of an event which warrants a change in a current power consumption state of the device. Any operating parameter value in the selected set that would prevent the device from meeting current operating demands is modified to a new value. The new value may be taken from another operating parameter set. The modified set of parameters is applied to the device in order to change the current power consumption state of the device.

摘要： In a power management scheme, at least one indicator of at least one current device operating condition that affects an amount of power required to operate a device may be received. Based on the at least one indicator, a floor value for an operating parameter of the device (e.g. clock frequency or voltage) may be determined. At least one further indicator of at least one current device operating condition may further be received. Based on the at least one further indicator, a ceiling value for the operating parameter may be determined. Based on an indicator of current activity of the device, the operating parameter may be dynamically adjusted to a value between the floor value and the ceiling value, to control power consumption by the device. In some embodiments, the value may be adjusted to only the ceiling value or the floor value, e.g. by selectively applying a scaling ratio.

摘要： A variable clock control information generator receives graphics engine activity data relating to the operating level of a graphics engine, and memory activity data relating to an activity level of memory. In response, the variable clock control information generator produces graphics engine clock control information and memory clock control information with respect to each other, such that a relative difference between the graphics engine activity data and the memory activity data is within balance threshold data. Accordingly, the variable clock control information generator adapts to the varying levels of graphics engine activity and memory activity and adjusts the frequency of the graphics engine clock signal and the frequency of the memory clock signal to achieve a balanced relative activity level.
