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. 本发明描述用于在图形处理单元GPU中执行高阶滤波的技术。在本发明的实例中，可在GPU的经修改的纹理引擎上使用单个着色器指令来实施高阶滤波。所述经修改的纹理引擎可经配置以获取所述高阶滤波所需的所有源像素，并将其连同预加载的滤波权重混合。
