Abstract: This disclosure describes techniques for performing high order filtering in a graphics processing unit (GPU). In examples of the disclosure, high order filtering may be implemented on a modified texture engine of a GPU using a single shader instruction. The modified texture engine may be configured to fetch all source pixels needed for the high order filtering and blend them together with pre-loaded filtering weights.

Abstract: A texture pipe of a graphics processing unit (GPU) may receive a texture data. The texture pipe may perform a block-based operation on the texture data, wherein the texture data comprises one or more blocks of texels. Shader processors of the GPU may process graphics data concurrently with the texture pipe performing the block-based operation. The texture pipe may output a result of performing the block-based operation on the one or more texture data.

Abstract: An example method of filtering in a graphics processing unit (GPU) may include storing, by a texture engine of the GPU, filter coefficients of a filter as a texture memory object (TMO) in a texture cache of the GPU in response to a first instruction. The method may include retrieving, by the texture engine, filter coefficients from the texture cache in response to a second instruction. The method may include storing, by the texture engine, pixel data in the texture cache of the GPU in response to the second instruction. The pixel data may include one or more pixel values. The method may include filtering, by the texture engine, the pixel data stored in the texture cache using the retrieved filter coefficients.

Abstract: This disclosure describes techniques for performing filtering in a graphics processing unit (GPU), The GPU may include a texture engine and a texture memory configured to store pixels and filter coefficients and at least one processor. The at least one processor may be configured to: store filter coefficients as a texture memory object (TMO) in the texture memory accessible to the texture engine in response to a first instruction, retrieve the filter coefficients from the texture memory in response to a second instruction, store pixels from the texture memory in a texture cache of the texture engine in response to the second instruction, and filter the pixels using the retrieved filter coefficients.
