    摘要: An image display system synchronizes the display of images on a plurality of display devices. The method entails generating at a first computer system a first signal representing first image data to be displayed on a first display device, generating at a second computer system a second signal representing second image data to be displayed on a second display device, and a method for synchronizing the first and second image data. The synchronizing method includes using a phase-locked loop circuit having a digital rate controller. The digital rate controller allows programmable control of the speed of the phase-locked loop.

    摘要: Various computing devices and methods of managing the power consumption thereby are disclosed. In one aspect, a method of managing power consumption of a computing device that has a battery is provided. The method includes cycling the computing device between a connected standby active state and a connected standby idle state. The duration of the connected standby idle state is set based at least in part on a charge level of the battery.

    摘要: A system and method for reducing power consumption of a video subsystem. A computer system includes multiple display devices supported by a graphics processor. A memory for storing video data for the multiple display devices utilizes multiple channels for higher bandwidth. A systems controller within the graphics processor determines a retraining condition, such as an idle power state, is satisfied for one or more channels of the multiple memory channels. The graphics processor divides each respective screen for the multiple display devices into multiple horizontal bars. For each one of the multiple horizontal bars, the corresponding data may be rearranged from being distributed across the multiple channels to being stored in a single one of the multiple channels. The systems controller determines a given channel is an upcoming free channel. This free channel is retrained while it is free. Retraining may include at least reducing its memory clock (MCLK) frequency.

    摘要: A method and apparatus to improve motion prediction in video processing systems is introduced. When a motion prediction cache completes requesting data for a current macroblock and enters an into idle state, data comprising one or more reference frames is speculatively requested, with the hope that the requested data are will be needed in a subsequent macroblock. If the speculative data is needed, then it is consumed. However, if the speculative data is not needed, then the correct data must be requested and a price is paid for an extra memory read bandwidth. In case the speculative data is the correct data for the subsequent macroblock, the effective memory read latency is reduced and the decode performance increases. The video decoder becomes more immune to memory read latency.
