Abstract: A method comprising the steps of generating a first representation and a second representation, where the first representation represents a first view of a computer-generated scene obtained from a first virtual camera and the second representation represents a second view of the computer-generated scene obtained from a second virtual camera. Each of the first and second representation comprises a plurality of rays which intersect with objects of the scene. A relationship is determined between a ray of the first representation and a ray of the second representation; which are grouped based on the relationship, to form a group of substantially similar rays. One or more of the groups of substantially similar rays are processed substantially simultaneously to produce a first a second rendered view of the computer-generated scene. The first the second rendered view are output to one or more display devices.

Abstract: A computer implemented method for performing convolutions between subsets of an input data array and a kernel resulting in subsets of an output data array. The method may include receiving an input data array and using positional data indicating the position of elements of the input data array to determine subsets of the input data array which contains at least one non-zero value data element; performing convolutions between the subsets of the input data array containing at least one non-zero value data element and a kernel to produce output data array subsets; and combining the output data subsets with the positional data to generate output data indicative of a completed output data array.

Abstract: A method comprising: obtaining pose data representative of a pose of a portable device during observation of an environment comprising an object; obtaining distance data representative of a distance between the object and a receiver during the observation of the environment, using at least one radio waveform reflected from the object and received by the receiver; and processing the pose data and the distance data to generate a topological model of the object.

Abstract: A method of producing a full resolution frame, comprising generating a tile representation of the frame. The tile representation comprises a plurality of tiles each associated with an area of the frame. The method also includes eliminating one or more predetermined portions of each tile and rendering retained portions of each tile to produce rendered tiles. The method also transforms the rendered tiles into processed tiles. The full resolution frame is then constructed from the processed tiles.

Abstract: Examples of the present disclosure relate to methods for processing image data. In one such example, first data representing a rendered image is received. In some cases, second data useable to identify at least one target region of the rendered image is received, the at least one target region being associated with a gaze direction of a viewer. A first portion of the first data is processed in accordance with a first data reduction rate to derive first processed data, the first portion representing the at least one target region. A second portion of the first data is processed in accordance with a second data reduction rate, different from the first data reduction rate. The second portion represents a further region of the rendered image, different from the at least one target image. At least the first processed data is outputted.

Abstract: A local object classifier using a set of object definitions to perform object classification in image frames. The local object classifier is arranged to detect an object in an image frame and determine whether to transmit image data for the detected object to a remote object classifier. In response to said determining, the local object classifier is arranged to transmit image data, derived from the image data representative of the image frame, to the remote object classifier. The local object classifier is also arranged to receive object data, representative of the detected object, from the remote object classifier.

Abstract: A master device has a buffer for storing data transferred from, or to be transferred to, a memory system. Control circuitry issues from time to time a group of one or more transactions to request transfer of a block of data between the memory system and the buffer. Hardware or software mechanism can be provided to detect at least one memory load parameter indicating how heavily loaded the memory system is, and a group size of the block of data transferred per group can be varied based on the memory load parameter. By adapting the size of the block of data transferred per group based on memory system load, a better balance between energy efficiency and quality of service can be achieved.

Abstract: A method and an apparatus are provided for generating an output frame from an input frame, in which the input frame is processed when generating the output frame. A region of a current input frame is compared with a region of a preceding input frame to determine if the region of the current input frame is similar to the region of the preceding input frame. When the region of the current input frame is determined to be similar to the region of the preceding input frame, information relating to processing performed on the region of the preceding input frame when generating a region of a preceding output frame is read, wherein the information is generated during the processing on the region of the preceding input frame. When the information indicates that the processing is unnecessary, a part or all of the processing of the region of the current input frame can be bypassed or eliminated.

Abstract: Address translation circuitry and a method of operating such a translation circuitry are provided. The address translation circuitry is configured to receive a first address used in a first addressing system and to translate it into a second address used in a second addressing system. Translation pipeline circuitry has plural pipeline stages configured to translate the first address into the second address over the course of the plural pipeline stages. Address comparison circuitry is configured to identify an address match condition when a received first address at least partially matches a previously received first address. Insertion circuitry is configured to determine a stage of progress of the previously received first address in the plural pipeline stages and to cause content of the stage of progress of the previously received first address to be unchanged at a next pipeline cycle when the address comparison circuitry identifies the address match condition.
