Abstract: Methods and apparatuses are disclosed for reporting texture footprint information. A texture footprint identifies the portion of a texture that will be utilized in rendering a pixel in a scene. The disclosed methods and apparatuses advantageously improve system efficiency in decoupled shading systems by first identifying which texels in a given texture map are needed for subsequently rendering a scene. Therefore, the number of texels that are generated and stored may be reduced to include the identified texels. Texels that are not identified need not be rendered and/or stored.

Abstract: A system, method, and computer program product are provided for multi-sample processing. The multi-sample pixel data is received and is analyzed to identify subsets of samples of a multi-sample pixel that have equal data, such that data for one sample in a subset represents multi-sample pixel data for all samples in the subset. An encoding state is generated that indicates which samples of the multi-sample pixel are included in each one of the subsets.

Abstract: A system, method, and computer program product are provided for multi-sample processing. The multi-sample pixel data is received and an encoding state associated with the multi-sample pixel data is determined. Data for one sample of a multi-sample pixel and the encoding state are provided to a processing unit. The one sample of the multi-sample pixel is processed by the processing unit to generate processed data for the one sample that represents processed multi-sample pixel data for all samples of the multi-sample pixel or two or more samples of the multi-sample pixel.

Abstract: A system, method, and computer program product are provided for coalescing memory access requests. A plurality of memory access requests is received in a thread execution order and a portion of the memory access requests are coalesced into memory order, where memory access requests included in the portion are generated by threads in a thread block. A memory operation is generated that is transmitted to a memory system, where the memory operation represents the coalesced portion of memory access requests.

Abstract: In computer graphics, texture refers to a type of surface, including the material characteristics, that can be applied to an object in an image. A texture may be defined using numerous parameters, such as color(s), roughness, glossiness, etc. In some implementations, a texture may be represented as an image that can be placed on a three-dimensional (3D) model of an object to give surface details to the 3D object. To reduce a size of textures (e.g. for storage and transmission), the present disclosure provides, in one embodiment, for compression of a texture set using a non-linear function and quantization. In another embodiment, the disclosure provides for compression of one or more textures using a non-linear function configured to compress textures with an arbitrary number of channels and/or an arbitrary ordering of channels.

Abstract: Techniques are disclosed herein for interleaving textures. In the disclosed techniques, multiple textures that would otherwise be accessed separately are interleaved into a single, interleaved texture that can be used to access the multiple textures together. The interleaved texture can include alternating blocks from the multiple textures. The interleaved texture can be generated when the multiple textures are being loaded into memory. Further, the interleaved texture can be accessed using multiple texture headers that are associated with different textures in the interleaved texture. Each of texture headers includes a stride indicating the distance between two blocks from a same texture in the interleaved texture.

Abstract: Various embodiments include a parallel processing computer system that detects memory errors as a memory client loads data from memory and disables the memory client from storing data to memory, thereby reducing the likelihood that the memory error propagates to other memory clients. The memory client initiates a stall sequence, while other memory clients continue to execute instructions and the memory continues to service memory load and store operations. When a memory error is detected, a specific bit pattern is stored in conjunction with the data associated with the memory error. When the data is copied from one memory to another memory, the specific bit pattern is also copied, in order to identify the data as having a memory error.
