Abstract: A technique for caching coverage information for edges that are shared between adjacent graphics primitives may reduce the number of times a shared edge is rasterized. Consequently, power consumed during rasterization may be reduced. During rasterization of a first graphics primitive coverage information is generated that (1) indicates cells within a sampling grid that are entirely outside an edge of the first graphics primitive and (2) indicates cells within the sampling grid that are intersected by the edge and are only partially covered by the first graphics primitive. The coverage information for the edge is stored in a cache. When a second graphics primitive is rasterized that shares the edge with the first graphics primitive, the coverage information is read from the cache instead of being recomputed.

Abstract: One embodiment of the present invention sets forth a compression status cache configured to store compression information for blocks of memory stored within an external memory. A data cache unit is configured to request, in response to a cache miss, compressed data from the external memory based on compression information stored in the compression status bit cache. The compression status for active buffers is dynamically swapped into the compression status cache as needed. Different compression formats may be specified for one or more tiles within an active buffer. One advantage of the disclosed compression status cache is that a lame amount of attached memory may be allocated as compressible memory blocks, without incurring a corresponding die area cost because a portion of the compression status stored off chip in attached memory is cached in the compression status cache.

Abstract: A solution is proposed that performs global histogramming of pre-regionally-enhanced pixel values accounting for inter-regional illumination contributions to verify that over-saturation of an image is prevented. According to an embodiment, pixel values that have been regionally enhanced—that is, with applied gains calculated for the respective regions—are further added to illumination values corresponding to the pixel values, with the resultant summed pixel values being histogrammed again to determine the amount of over-saturated pixels. An over-abundance of over-saturated pixels results in a calculation of a global modifier applied to each pixel to reduce the number of over-saturated pixels below an acceptable threshold.

Abstract: Raw video data is captured, processed, and then stored within a set of buffers. An encoder engine is configured to encode the video data for storage. A feedback controller dynamically adjusts the clock frequency of the encoder engine based on the number of buffers currently occupied by the video data. The feedback controller is tuned so that the clock frequency of the encoder engine will be increased when the number of buffers occupied by video data increases, and the clock frequency of the encoder engine will be decreased when the number of buffers occupied by the video data decreases.

Abstract: A solution is proposed that allows power savings via enhancement of pixel data to compensate for reducing backlight intensity levels. According to one embodiment, each pixel of a display is sorted according to the brightness (intensity) of the pixel. Regional pixel gains are calculated and applied on a per pixel basis so as not to exceed a quality threshold. The intensity of the backlight corresponding to each region may be decreased by an equivalent amount, thereby reducing (potentially significantly) the power consumed to operate the backlight while maintaining the color intensity in the image due to the applied pixel gains.

Abstract: An aspect of the present invention proposes a solution to allow low-cost flat panel displays without light guides to maintain a high quality image display via enhancement of pixel data to account for non uniform brightness. According to one embodiment, each pixel of a display is mapped to the brightness (intensity) of illumination that reaches the pixel. Regional pixel gains are calculated and applied on a per pixel basis to compensate for the non-uniform brightness across the screen. According to such an embodiment, even low cost flat panel displays experiencing non-uniform brightness can be used to render high quality images.

Abstract: The range of depth values within the overlap of a convex polygon and a square or rectangular rasterization area can be determined by identifying whether the minimum and maximum depth values occur at the corners of the rasterization area or at intersections of the polygon's edges with the area's sides. By choosing between the corner and intersection for both the minimum and maximum depth limit, solving the depth plane equation at the chosen location, and clamping against the polygon's vertex depth range, a tight depth range describing the depth values within that overlap are obtained. That tight depth range is utilized to cull pixel values early in the pipeline, improving performance and power consumption.

Abstract: One embodiment of the present invention sets forth a technique for displaying high-resolution images using multiple graphics processing units (GPUs). The graphics driver is configured to present one virtual display device, simulating a high-resolution mosaic display surface, to the operating system and the application programs. The graphics driver is also configured to partition the display surface amongst the GPUs and transmit commands and data to the local memory associated with the first GPU. A video bridge automatically broadcasts this information to the local memories associated with the remaining GPUs. Each GPU renders and displays only the partition of the display surface assigned to that particular GPU, and the GPUs are synchronized to ensure the continuity of the displayed images. This technique allows the system to display higher resolution images than the system hardware would otherwise support, transparently to the operating system and the application programs.
