Abstract: A processor uses the same virtual address space for heterogeneous processing units of the processor. The processor employs different sets of page tables for different types of processing units, such as a CPU and a GPU, wherein a memory management unit uses each set of page tables to translate virtual addresses of the virtual address space to corresponding physical addresses of memory modules associated with the processor. As data is migrated between memory modules, the physical addresses in the page tables can be updated to reflect the physical location of the data for each processing unit.

Abstract: Embodiments are described for a method for using anti-aliasing hardware to generate a higher resolution image at the processing of a lower resolution image with anti-aliasing. A graphics image comprising allocating a buffer used in a multisample anti-aliasing process, wherein the allocated buffer has a dimension comprising a reduction in at least one of the width or height of an original dimension of an original buffer provided by the anti-aliasing hardware; rendering sampled image data to the allocated buffer at a sampling rate proportional to the reduction; and expanding the allocated buffer back to the dimension of the original buffer.
