Abstract: A hierarchical memory request stream arbitration technique merges coherent memory request streams from multiple memory request sources and arbitrates the merged coherent memory request stream with requests from a non-coherent memory request stream. In at least one embodiment of the invention, a method of generating a merged memory request stream from a plurality of memory request streams includes merging coherent memory requests into a first serial memory request stream. The method includes selecting, by a memory controller circuit, a memory request for placement in the merged memory request stream from at least the first serial memory request stream and a merged non-coherent request stream. The merged non-coherent memory request stream is based on an indicator of a previous memory request selected for placement in the merged memory request stream.

Abstract: System and method for providing control data for dynamically adjusting lighting and adjusting video pixel data for a display to substantially maintain image display quality while reducing power consumption. In accordance with one or more embodiments, image statistics, e.g., histogram data representing luma values corresponding to pixels for a video frame, are analyzed to determine whether the pixels represent one or more of a plurality of images which includes an image containing primarily natural imagery, an image containing primarily graphics imagery, and an image containing a combination of at least respective portions of natural and graphics imagery. Based on such analysis, control data are provided to enable light source brightness reduction by one of a plurality of percentages and pixel brightness increases, e.g.
