MUMBAI, India, July 25 -- Intellectual Property India has published a patent application (202518066998 A) filed by Advanced Micro Devices, Inc., Santa Clara, U.S.A., on July 14, for 'performing anti-aliasing operations in a computing system.'
Inventor(s) include Fainstain, Evgene.
The application for the patent was published on July 25, under issue no. 30/2025.
According to the abstract released by the Intellectual Property India: "Systems, apparatuses, and methods for performing hybrid anti-aliasing operations are disclosed. The hybrid anti-aliasing resolve operation combines multi-sampling anti-aliasing and post-processing anti-aliasing to generate higher-quality images in a computationally efficient manner. In one embodiment, a processor (130) detects a request to perform an antialiasing resolve operation on an image stored in the memory (150). Responsive to detecting the request, the processor expands dimensions of the image and then filters the image with a post-processing anti-aliasing filter. After filtering the image, the processor performs an averaging of the image which becomes the result of the anti-aliasing resolve operation. Expanding dimensions of the image involves converting sub-pixels of the image into regular pixels. The processor can also rotate the image to align the sub-pixels into a vertical and horizontal grid pattern prior to filtering the image. Also contemplated are embodiments of a processor configured to generate, based on a rotated grid, a plurality of sub-pixel sampling coordinates for each pixel of an image being rendered where an amount of rotation is specified for the rotated grid, sample sub-pixel locations indicated by the plurality of subpixel sampling coordinates within each pixel of the image being rendered by a plurality of execution units, and store values of the sub-pixel locations in a memory."
The patent application was internationally filed on Jan. 17, 2017, under International application No.PCT/US2017/013786.
