  • Patent number: 10657700
    Abstract: Ray tracing systems have computation units (“RACs”) adapted to perform ray tracing operations (e.g. intersection testing). There are multiple RACs. A centralized packet unit controls the allocation and testing of rays by the RACs. This allows RACs to be implemented without Content Addressable Memories (CAMs) which are expensive to implement, but the functionality of CAMs can still be achieved by implemented them in the centralized controller.

  • Patent number: 10600143
    Abstract: The present disclosure describes techniques for removing unnecessary processing stages from a graphics processing pipeline based on the format of data passed between the stages. Starting with a stage at a middle point in a pipeline, formats of data that are input to and output from the middle stage may be compared to each other. If the formats match, the middle stage may be removed from the pipeline. Thereafter, the format of data input to a pair of middle stages of the pipeline and output from the pipeline may be compared and, if they match, the middle pair may be deleted. This process may repeat until a middle pair is found where no match occurs between the input and output format. The remaining stages of the pipeline may be retained. In cases where a pipeline is not symmetrical, the formats of data at each node may be compared to each other.

  • Patent number: 10529049
    Abstract: Techniques are provided herein for generating an integral image of an input image in parallel across the cores of a multi-core processor. The input image is split into a plurality of tiles, each of which is stored in a scratchpad memory associated with a distinct core. At each tile, a partial integral image of the tile is first computed over the tile, using a Single-Pass Algorithm. This is followed by aggregating partial sums belonging to subsets of tiles using a 2D Inclusive Parallel Prefix Algorithm. A summation is finally performed over the aggregated partial sums to generate the integral image over the entire input image.
