Methods, software, and apparatuses for graphics processing, including caching pixel data of one or more tiles of a graphics surface. Methods generally include setting a caching bit corresponding to the surface, setting tile pattern bits corresponding to tiles in the surface, and when the caching bit is active, storing one or more pixel values in a cache memory. When at least one tile contains pixels having the same value for at least one predetermined parameter, the caching bit and the corresponding tile pattern bits may be active. Apparatuses generally include a pixel memory, a cache memory, and a controller including logic configured to reserve the caching bit, tile pattern bits, and same pixel values in cache memory when the caching bit is active.

Methods and apparatuses for processing cached image data

Embodiments of the present invention provide methods and associated architecture of accuracy adaptive and scalable vector graphics rendering including rendering a graphic comprising a plurality of line segments by processing each of the plurality of line segments in a first pass, and processing each of a plurality of pixels through which the plurality of line segments pass in a second pass, automatically detecting one or more rendering errors of the graphic, and correcting the one or more rendering errors. Other embodiments may be described and/or claimed.
