摘要： A graphics processing system processes primitive fragments using a rendering space which is subdivided into tiles. The graphics processing system comprises processing engines configured to apply texturing and/or shading to primitive fragments. The graphics processing system also comprises a cache system for storing graphics data for primitive fragments, the cache system including multiple cache subsystems. Each of the cache subsystems is coupled to a respective set of one or more processing engines. The graphics processing system also comprises a tile allocation unit which operates in one or more allocation modes to allocate tiles to processing engines. The allocation mode(s) include a spatial allocation mode in which groups of spatially adjacent tiles are allocated to the processing engines according to a spatial allocation scheme, which ensures that each of the groups of spatially adjacent tiles is allocated to a set of processing engines which are coupled to the same cache subsystem.

摘要： When untransformed display lists are used in a tile-based graphics processing system, the processing involved in deriving sub-primitives may need to be performed in both the geometry processing phase and the rasterisation phase. To reduce the duplication of this processing, the control stream data for a tile includes sub-primitive indications to indicate which sub-primitives are to be used for rendering a tile. This allows the sub-primitives to be determined efficiently in the rasterisation phase based on this information determined in the geometry processing phase. Furthermore, a hierarchical cache system may be used to store a hierarchy of graphics data items used for deriving sub-primitives. If graphics data items for deriving a sub-primitive are stored in the cache, the retrieval of these graphics data items from the cache in the rasterisation phase can reduce the amount of processing performed to derive the sub-primitives.
