Abstract: A graphics processing system includes a processing circuit operable to render or decode a sequence of frames and generate extrapolated frames by extrapolating object motion from rendered or decoded frames. The system also includes a processing circuit operable to extrapolate object motion from first and second rendered or decoded frames in the sequence to a later extrapolated frame. The processing circuit is also operable to test candidate motion vectors from a region of the extrapolated frame through a region of the first frame to a region of the second frame by comparing the region of the first frame with the region of the second frame. A similarity measure from the comparison is used to select a motion vector and an indication representative of the selected motion vector is stored.

Abstract: Examples of the present disclosure relate to a method for reducing artefacts caused by the presence of flicker during capture of a video. A sequence of frames of the video are captured, the frames each comprising a plurality of predefined regions each comprising a plurality of pixels. A time-varying oscillation of the flicker is characterized based on variations, across the sequence of frames, of data relating to pixel intensities in at least one said region. Based on the characterizing of the time-varying oscillation of the flicker, a flicker correction is applied to a frame of the video.

Abstract: The present disclosure relates to a data processing resource for performing data processing tasks for a host processor, the data processing resource comprising: control circuitry to receive, from the host processor, a request for the data processor unit to perform a processing job; an iterator unit to process the request and generate a workload comprising one or more tasks for the requested processing job; one or more execution units to perform the one or more tasks, wherein the iterator unit is configured to allocate the one or more tasks to the one or more execution units based on control signals from the control circuitry, wherein the control circuitry is further configured to switch an operation mode of at least one execution unit from a normal operation mode to a reduced operation mode by controlling the iterator unit to reduce an amount of task allocated to the at least one execution unit.

Abstract: According to the present techniques there is provided a method of operating a data processor unit to generate processing tasks: the data processor unit comprising: a control circuit to receive, from a host processor unit, a request for the data processor unit to perform a processing job; an iterator unit to process the request and generate a workload comprising one or more tasks for the requested job; one or more execution units to perform the one or more tasks; storage to store system information indicative of a status of at least one component of the data processor unit; the method comprising: receiving, at the control circuit, a first request to perform a first processing job; processing, at the iterator unit, the first request and generating a workload comprising one or more tasks for the first processing job based on or in response to the system information in storage, wherein at least one characteristic of the workload is dependent on the system information.

Abstract: A method comprising the steps of obtaining at least one frame of input data from at least one sensor, the frame of input data representative of a real-world environment at a given time. The frame is analysed to determine at least a foveal region within the frame, and at least a method for generating depth information associated with the real-world environment based on the frame of input data is selected. The method is applied to the foveal region to generate depth information associated with the foveal region, and at least the depth information associated with the foveal region is outputted.
