Abstract: A stable frame rate is maintained by a system that includes a graphics processing unit (GPU). The system also includes memory to store frames rendered by the GPU, and a display to display the frames rendered by the GPU. In response to a negative indication with respect to the GPU maintaining a frame rate at an operating frequency, the GPU is operative to reduce frame quality of subsequent frames while maintaining the operating frequency.

Abstract: A graphics accelerator device offloads the workload of a graphics processing unit (GPU) by performing image composition and other specialized functions. The graphics accelerator device includes a rasterization module to rasterize a set of primitives to a set of pixels and generate information of the set of pixels. The graphics accelerator device also includes intra-process module to retrieve pixel values from a memory according to the information received from the rasterization module, perform mathematical calculations on the pixel values, and generate one or more processed image layers. The graphics accelerator device further includes an inter-process module to composite the one or more processed image layers received from the intra-process module with other image layers retrieved from the memory, and output a composited image to a display.

Abstract: Techniques pertaining to dynamic enablement, disablement and adjustment of offset of a virtual periodic timing control signal based on one or more predefined events are described. A method may determine whether a first predefined event is beginning. The method may also enable an offset of the virtual periodic timing control signal for synchronizing one or more first system modules in response to a determination that the first predefined event is beginning. The one or more first system modules may be configured to control one or more operations of one or more second system modules. The one or more second system modules may be configured to process one or more image frames. The method may further determine whether the first predefined event is ending. The method may additionally disable the offset in response to a determination that the first predefined event is ending.
