Abstract: Aspects of this disclosure relate to a process for rendering graphics that includes designating a hardware shading unit of a graphics processing unit (GPU) to perform first shading operations associated with a first shader stage of a rendering pipeline. The process also includes switching operational modes of the hardware shading unit upon completion of the first shading operations. The process also includes performing, with the hardware shading unit of the GPU designated to perform the first shading operations, second shading operations associated with a second, different shader stage of the rendering pipeline.

Abstract: This disclosure describes techniques for performing memory transfer operations with a graphics processing unit (GPU) based on a selectable memory transfer mode, and techniques for selecting a memory transfer mode for performing all or part of a memory transfer operation with a GPU. In some examples, the techniques of this disclosure may include selecting a memory transfer mode for performing at least part of a memory transfer operation, and performing, with a GPU, the memory transfer operation based on the selected memory transfer mode. The memory transfer mode may be selected from a set of at least two different memory transfer modes that includes an interleave memory transfer mode and a sequential memory transfer mode. The techniques of this disclosure may be used to improve the performance of GPU-assisted memory transfer operations.
