    摘要： A method for performing neural network processing, and a corresponding data processing system. The data processing system is configured to define one or more tiles for use when reading a portion of an input feature map from memory or writing a portion of an output feature map to memory. The data processing system is also configured to provide information which allows positions falling within the defined one or more tiles to be mapped to memory locations to allow a processor to read data for an input feature map from memory or to write data for a portion of an output feature map to memory.

    摘要： An apparatus for encoding frames of a sequence of source frames of video image data to be encoded. The apparatus includes encoding circuitry configured to encode the source frames using reference frames. The apparatus also includes monitoring circuitry configured to, when the encoding circuitry is encoding a source frame using one or more reference frames, monitor the memory bandwidth being used when using the one or more reference frames when encoding the source frame. The apparatus further includes encoding circuitry that is operable to, in response to the monitored memory bandwidth being greater than a threshold, to control the encoding circuitry to encode a subsequent part of the source frame using a modified video encoding process to restrict the memory bandwidth usage when using one or more reference frames when encoding a subsequent part of a source frame.

    摘要： An apparatus for decoding a sequence of frames of encoded video data includes parsing circuitry configured to parse the encoded video image data for a frame to derive encoding information for each block of the frame. The apparatus also includes feedback circuitry configured to feed back, to the parsing circuitry, encoding information for a frame for use when parsing the encoded video image data of the next frame. The encoding information includes an encoding indicator for each block. When the encoding indicators were enabled when encoding the blocks of the frame, the encoding indicator fed back for a block is the encoding indicator that was used to encode that block. When the encoding indicators for the blocks of the frame were disabled when encoding the video image data for the frame, the encoding indicator fed back for a block is an encoding indicator derived from a previous frame.

    摘要： When performing anisotropic filtering when sampling a texture to provide an output sampled texture value for use when rendering an output in a graphics processing system, a number of positions for which to sample the texture along an anisotropy direction along which samples will be taken in the texture is determined by determining the square root of the coefficient F for an ellipse having the form Ax2+Bxy+Cy2=F corresponding to the projection of the sampling point for which the texture is being sampled onto the surface to which the texture is to be applied, and using the determined square root of the ellipse coefficient F to determine the number of positions for which samples should be taken along the anisotropy direction in the texture.
