Abstract: A data array to be stored is first divided into a plurality of blocks. Each block is further sub-divided into a set of sub-blocks.Data representing sub-blocks of the data array is stored, together with a header data block for each block that the data array has been divided into.For each block, it is determined whether all the data positions for the block have the same data value associated with them, and, if so, an indication that all of the data positions within the block have the same data value associated with them, and an indication of the same data value that is associated with each of the data positions in the block, is stored in the header data block for that block of the data array.

Abstract: A graphics processor operable to render frames that represent a view of a scene using a ray tracing process includes a ray tracing circuit operable to test rays against a ray tracing acceleration data structure for a ray tracing process. The ray tracing circuit comprises a ray testing circuit operable to perform ray intersection tests for nodes of a ray tracing acceleration data structure and storage local to the ray testing circuit for storing data representative of one or more nodes of a ray tracing acceleration data structure for use by the ray testing circuit. Rays for testing by the ray testing circuit are selected from a pool of one or more rays to be tested based on an indication of the ray tracing acceleration data structure node or nodes that have been stored in the local storage of the ray testing circuit.

Abstract: A method of operating a graphics processor to perform ray tracing. The graphics processor includes a ray tracing circuit that can be messaged by the graphics processor's programmable execution unit during execution of a program to perform a respective traversal of the at least one ray tracing acceleration data structure to be traversed for that ray. The ray tracing circuit when returning rays' processing to the programmable execution unit is operable to group rays together for continued execution by the programmable execution unit as a respective thread group.

Abstract: A method of operating a graphics processor to perform ray tracing. The graphics processor includes a ray tracing circuit that can be messaged by the graphics processor's programmable execution unit during execution of a program to perform a respective traversal of the at least one ray tracing acceleration data structure to be traversed for that ray. The ray tracing circuit may need to stop a ray's traversal to return the ray's processing to the programmable execution unit before the ray's traversal is subsequently restarted. In that case, the ray's traversal is restarted from the beginning.

Abstract: A graphics processor performs graphics processing in respect of a region of a render output. The graphics processing comprises obtaining a scaling factor corresponding to a desired resolution for the region. The graphics processing further comprises, in accordance with the desired resolution, obtaining scaled graphics geometry to be rendered for the region and selecting a subregion of the region to be rendered in respect of the region. The selected subregion is then rendered using the scaled graphics geometry, thereby providing a subregion of data elements rendered in accordance with the desired resolution. The graphics processor can provide efficient and flexible graphics processing when performing variable resolution rendering.

Abstract: Disclosed herein is a method and apparatus for determining decoded data values for a data element of an array of data elements from an encoded representation of the array of data elements, wherein the decoding comprises determining which, if any, bits are missing for the data value(s) for the data element and selecting based on this an adjustment scheme to be applied for the data value(s) for the data element from a plurality of available adjustment schemes. Also disclosed are a method and apparatus for generating an encoding hint comprising an indication of the one or more encoding parameters that were used to generate the encoded representation which encoding hint can then be associated with the decoded data and then used when the decoded data is subsequently to be encoded.

Abstract: A data processing system includes a producer processor that produces a sequence of data outputs for use by consumer processors of the data processing system. The system also includes a memory for storing a sequence of data outputs produced by the data processor. The data processor encodes data outputs as encoded blocks of data, storing a particular encoded block of a first frame in a first location in the memory and an indication of the first location. The data processor stores a corresponding encoded block of a second data output in a second location and updates the indication to the second location.

Abstract: An image processing apparatus and method including an encoder circuitry for generating encoded data blocks from input data blocks of an image, and write circuitry for storing the encoded data blocks to memory for subsequent access by decoding circuitry. For each input data block, identifier generation circuitry generates an identifier value that is dependent on the input data block. A lookup storage stores predetermined information relating to at least one encoded data block and stored within the lookup storage in association with the identifier value for the corresponding input data block. For a current input data block, a check is performed to determine whether a match exists between the identifier value generated for the current input data block and an identifier value stored in the lookup storage. In a match, the predetermined information is used by the write circuitry when performing the required write operation.

Abstract: A method of operating a graphics processor when performing a certain sequence of rendering jobs that produces a series of progressively lower resolution versions of the same render output comprising issuing rendering tasks for different rendering jobs concurrently and controlling processing for a later rendering job using a respective ‘task completion status’ data structure associated with the earlier rendering job on which it depends, wherein the looking up of respective entries in the ‘task completion status’ data structure takes into account the change in resolution between the first, earlier rendering job and the second, later rendering job.
