Abstract
Prescient cache management methods and systems are disclosed. In one embodiment, a local cache that operates within a raster engine operations stage of a graphics rendering pipeline is managed by following a number of caching decisions related to a number of cached tiles. Each of these cached tiles has a certain priority to remain in the local cache, with the priority corresponding to a conflict type received from a buffer operating within a pre-raster engine operations stage of the graphics rendering pipeline.
