Abstract: A method of processing image data representative of an image using a multi-stage system comprising a first neural network (NN) for identifying a first image characteristic and a second NN for identifying a second image characteristic. The method comprises processing the image data using t a first at least one layer of the first NN to generate feature data representative of at least one feature of the image and processing the feature data using a second at least one layer of the first NN to generate first image characteristic data indicative of whether the image includes the first image characteristic. The feature data is transferred from the first NN to the second NN. The feature data is processed using the second NN to generate second image characteristic data representative of whether the image includes the second image characteristic.

Abstract: A method of processing a frame in a data processing system is provided, in which the frame comprises one or more frame regions that together form the frame, and each frame region is represented as one or more data values, with each data value being represented by a set of data. The method comprises, for at least one region of the frame, when a memory access operation is to be performed for the region of the frame, comparing (163) a portion of the data representing data values for the frame region (165) with a corresponding portion of the data representing the corresponding data values for a previous frame region (162), which is a frame region for which the memory access operation has been performed, to determine if the portion of the data representing the data values for the frame region is similar to the corresponding portion of the data representing the data values for the previous frame region, wherein the portion of the data representing the data values for a frame region comprises a sub-set of controller data (167a, 167b) from each set of data representing a data value of the data values for the frame region. In an embodiment, if the portion of the data representing the data values for the frame region is determined to be similar to the corresponding portion of the data representing the data values for the previous frame region, the memory access operation is omitted, or, if the portion of the data representing the data values for the frame region is determined not to be similar to the corresponding portion of the data representing the data values for the previous frame region, the memory access operation is performed (169).

Abstract: The technology described herein relates to a method of generating an encoded output video frame for transmission to an electronic display in which an encoded source video frame is decoded to obtain a decoded source video frame 200a, the decoded source video frame 200a is processed to obtain an input video frame 200c, and the input video frame 200c is encoded to obtain an encoded output video frame for transmission. The method comprises comparing a region of an input video frame 200c with a region of a decoded source video frame 200a from which decoded source video frame the input video frame has been obtained, to determine if the region of the decoded source video frame 200a is similar to the region of the input video frame 200c, and if it is determined that the region of the decoded source video frame 200a is similar to the region of the input video frame 200c, using a region of the encoded source video frame that corresponds to the region of the decoded source video frame as a region of the encoded output video frame for transmission that corresponds to the region of the input video frame.

Abstract: A graphics processing system generates output frames for display on a display. Comparison and control hardware of a display controller of the graphics processing system operates to compare successive output frames that are being generated for display, and then controls one or more aspects of the way in which the display of the output frames is carried out. In one embodiment, the display device or a frame buffer is partially updated (refreshed) by the display controller on the basis of comparisons of composited output frames.

Abstract: Apparatus and a corresponding method for processing image data are provided. The apparatus has compositing circuitry to generate a composite layer for a frame for display from image data representing plural layers of content within the frame. Plural latency buffers are provided to store at least a portion of the image data representing the plural layers. At least one of the plural latency buffers is larger than at least one other of the plural latency buffers. The compositing circuitry is responsive to at least one characteristic of the plural layers of content to allocate the plural layers to respective latency buffers of the plural latency buffers. Image data information for a layer allocated to the larger latency buffer is available for analysis earlier than that of the layers allocated to the smaller latency buffers and processing efficiencies can then result.

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.

Abstract: An information processing apparatus is described for processing a workload. The information processing apparatus comprises a processor and a memory element connected to the processor via a data link. In advance of processing a workload, the information processing apparatus estimates an access time required to transfer an amount of the workload that is to be transferred from the external memory element to the processor, and estimates a processing time for the processor to process the workload. A processing rate characteristic of the processor and/or a data transfer rate between the memory and the processor is set in dependence upon the estimated processing time and estimated access time. Methods for varying a quality of service (QoS) value of requests to the external memory element are also described.

Abstract: A vehicle-assist system comprising one or more sensors to monitor an environment of a vehicle and an eye-tracking system, including an eye-tracking sensor, to determine a gaze characteristic of a driver of the vehicle. The vehicle-assist system is to detect a hazard, and determine a hazard location of the hazard, in the environment of the vehicle. Based on the hazard location and the gaze characteristic of the driver, the vehicle-assist system is to output an indication of the hazard to the driver.
