Abstract: When processing a set of tiles to generate an output in a tile based graphics processing pipeline, the pipeline, for one or more tiles of the set of tiles, renders one or more render targets containing data to be used in a processing operation (602), and stores the render targets in the tile buffer (604). It also stores some but not all of the sampling position values for a render target or targets for use when processing an adjacent tile of the set of tiles (606). It then performs a processing operation for the tile using the stored render target or targets (608) and one or more stored sampling position values from another, adjacent tile of the set of tiles (610), to generate an output for the tile (612).

Abstract: A graphics processing apparatus (2) performs tile based compositing operations. Tile metadata includes flag data (tfd), such as transparency and/or intensity flag data, indicating whether a given input graphics tile make less than a predetermined first threshold level of contribution or more than a second predetermined threshold level of contribution to a corresponding output graphics tile. For example, if an input graphics tile is transparent, then its reading from a memory (6) and/or subsequent processing may be suppressed. If a given input graphics tile is opaque, then any underlying input graphics tiles were are obscured may have their reading and/or further processing suppressed.

Abstract: In a tile-based graphics processing system, when a tile for a render output is to be generated, the fragment data storage requirements for each fragment to be generated for the tile is determined 51, and a colour and/or depth buffer in the tile buffer is allocated for use by the fragments for the tile based on the determination 57. The graphics processing pipeline then, when generating rendered fragment data for the tile, stores the rendered fragment data in the colour buffer and/or depth buffer of the tile buffer allocated to the fragments for the tile 58.

Abstract: A data processing system 30 includes a CPU 33, a GPU 34, a video processing engine (video engine) 35, a display controller 36 (or an image processing engine) and a memory controller 313 all having access to off-chip memory 314. A frame to be displayed is generated by, for example, being appropriately rendered by the GPU 34 or video engine 35. The display controller 36 (or the image processing engine) then performs display modifications, such as luminance compensation, on the frame to provide an output frame for display.The display controller 36 (or the image processing engine) also provides display modification information (such as determined luminance compensation parameters) to the GPU 33 and video engine 34. The display modification information is then used to modify the data that is generated for a frame to be displayed.

Abstract: A data processing system includes a host processor and a graphics processing unit operable to process data under the control of an operating system executing on the host processor. The graphics processing unit can be switched between a normal mode of operation in which the it has read and write access to data that is stored in non-protected memory regions 9 but no or write-only access to any protected memory regions 8, and a protected mode of operation in which it has read and write access to data that is stored in protected memory regions 8 but only has read-only access to any non-protected memory regions 9. The data processing system further comprises a mechanism for switching the graphics processing unit from its normal mode of operation to the protected mode of operation, and from its protected mode of operation to the normal mode of operation.

Abstract: When encoding an array of texture data elements to be used in a graphics processing system, the array of texture data elements is divided into a plurality of non-rectangular sub-sets of texture data elements, and each non-rectangular sub-set of texture data elements that the texture has been divided into is then encoded to generate an encoded texture data block representing that non-rectangular sub-set of the texture data elements, to thereby provide a set of encoded texture data blocks representing the texture.

Abstract: In a data processing system, an output surface, such as frame to be displayed, is generated as a plurality of respective regions with each respective region of the output surface being generated from a respective region or regions of one or more input surfaces. When a new version of the output surface is to be generated 80, for each region of the output surface it is determined which region or regions of the input surface or surfaces contribute to the region of the output surface 84 and then checked whether the contributing region or regions of the input surface or surfaces have changed since the previous version of the output surface region was generated 85. If there has been a change in the contributing region or regions of the input surface or surfaces since the previous version of the region in the output surface was generated 86, the region of the output surface is regenerated 87.
