ABSTRACT:
Prescient cache management methods and systems are disclosed. In one embodiment, within a pre-raster engine operations stage in a graphics rendering pipeline, tile entries are stored in a buffer. Each of these tile entries is related a transaction request that enters the pre-raster engine operations stage and has a screen coordinates field and a conflict field. If this buffer includes a first tile entry, which is related to a first transaction request associated with a first tile, and a second tile entry, which is related to a second transaction request that enters the pre-raster engine operations stage after the first transaction request and is also associated with the first tile, the conflict field of the first tile entry is updated with a conflict type that reflects a number of tile entries between the first tile entry and the second tile entry.
