  • Patent number: 10008029
    Abstract: Updating depth related graphics data is described. Geometric primitives are processed. Pixels are generated from the primitives based on the processing, each of which has at least one corresponding depth value. Culling is performed on a first group of the pixels, based on a representation of the at least one depth related value corresponding to each. Pixels may be discarded based on the culling and upon which a second group of pixels remain. A depth related raster operations function is performed, in which data is transacted with a depth buffer. The culling function is updated in relation to the transacting. The updating is performed on the basis of a granularity, which characterizes the culling function.

  • Patent number: 9916680
    Abstract: Techniques are disclosed for suppressing access to a depth processing unit associated with a graphics processing pipeline. The method includes receiving a graphics primitive from a first pipeline stage associated with the graphics processing pipeline. The method further includes determining that the graphics primitive is visible over one or more graphics primitives previously rendered to a frame buffer, and determining that the depth buffer is in a read-only mode. The method further includes suppressing an operation to transmit the graphics primitive to the depth processing unit. One advantage of the disclosed technique is that power consumption is reduced within the GPU by avoiding unnecessary accesses to the depth processing unit.
