摘要： A video encoding apparatus for encoding a video stream comprises a reference frame cache for reference frame video data retrieved from a reference frame storage unit in external memory, which is derived from an individual frame of the video stream. First and second source frame storage units store first and second blocks of unencoded video data taken from first and second source frames of the video stream, respectively. First and second video encoders perform first and second encoding operations to encode the first and second blocks of unencoded video data with reference to the reference frame video data cached in the reference frame cache, respectively. The first video encoder and the second video encoder perform the first encoding operation and the second encoding operation in parallel with one another.

摘要： A data processing apparatus is provided, configured to carry out data processing operations on behalf of a main data processing apparatus, comprising a coprocessor core configured to perform the data processing operations and a reset controller configured to cause the coprocessor core to reset. The coprocessor core performs its data processing in dependence on current configuration data stored therein, the current configuration data being associated with a current processing session. The reset controller is configured to receive pending configuration data from the main data processing apparatus, the pending configuration data associated with a pending processing session, and to store the pending configuration data in a configuration data queue. The reset controller is configured, when the coprocessor core resets, to transfer the pending configuration data from the configuration data queue to be stored in the coprocessor core, replacing the current configuration data.

摘要： A video data processing apparatus is provided comprising processing circuitry for performing video processing operations requiring access to video reference frames, and a memory management unit configured to translate virtual addresses into physical addresses. Translation circuitry is provided responsive to a memory access request for reference frame pixel data issued by the processing circuitry to perform a translation process on video reference frame information such that the set of input values for at least one hash function in the memory management unit comprises video reference frame identifier bits contained with the video reference frame information. This approach has been found to reduce the frequency of aliasing in the memory management unit when retrieving video reference frames.

摘要： A data processing apparatus and method and provided for handling vector instructions. The data processing apparatus has a register data store with a plurality of registers arranged to store data elements. A vector processing unit is then used to execute a sequence of vector instructions, with the vector processing unit having a plurality of lanes of parallel processing and having access to the register data store in order to read data elements from, and write data elements to, the register data store during the execution of the sequence of vector instructions. A skip indication storage maintains a skip indicator for each of the lanes of parallel processing. The vector processing unit is responsive to a vector skip instruction to perform an update operation to set within the skip indication storage the skip indicator for a determined one or more lanes. The vector processing unit is responsive to a vector operation instruction to perform an operation in parallel on data elements input to the plurality of lanes of parallel processing, but to exclude from the performance of the operation any lane whose associated skip indicator is set. This allows the operation specified by vector instructions to be performed conditionally within each of the lanes of parallel processing without any modification to the vector instructions that are specifying those operations.

摘要： An image processing method comprises receiving a raw color image as produced by an image sensor. A color image having a plurality of pixels is generated by processing raw image data from said raw color image, wherein pixels for which color values are absent in said raw image data are assigned color values derived from present color values in said raw image data. A sharpening term is generated by processing raw image data from said raw color image. Then, an improved color image is produced by combining said color image with said sharpening term. The raw color image may be a Bayer image, and the image processing method may be implemented in a cost and power efficient integrated circuit using limited memory.

摘要： In a transformer or a reactor having at least one winding of foil-formed electrical conductor material, a magnetic-flux-controlling spirally-wound sheet of highly permeable ferro-magnetic material is arranged axially outside each end of the winding. The ends of the sheet are galvanically connected to the foil winding. By division of the magnetic material in the sheet, a high resistance in the longitudinal direction of the sheet, and thus lower losses, are obtained.

摘要： The present invention provides filter circuitry for reducing noise in an input stream of image signals having luminance and chrominance components. Spatial filter circuitry is provided which, for a current image signal of the input stream, generates a spatially filtered internal signal from at least the luminance component of the current image signal. Comparison circuitry is configured to compare the current image signal with temporal data derived from multiple image signals of the input stream, and to generate a control signal dependent on the comparison. Combining circuitry is then used to combine, in a ratio determined by the control signal, the spatially filtered internal signal with at least a luminance component derived from the temporal data, in order to generate at least the luminance component of a current output image signal that forms a noise reduced version of the current image signal. Such a form of filter circuitry has been found to provide a filtered stream of image signals with significant noise suppression, and is particularly well suited to providing a filtered stream of image signals for input to video encoding circuitry, enabling significant improvements in the efficiency of the encoding circuitry by virtue of the manner in which the noise is suppressed.
