The processor comprises a plurality of data processing units; and a plurality of SIMD (Single Instruction Multiple Data) controllers, each connectable to a group of data processing units of the plurality of data processing units, and each SIMD controller arranged to handle an individual processing task with a subgroup of actively connected data processing units selected from the group of data processing units. The parallel processor is arranged to vary dynamically the size of the subgroup of data processing units to which each SIMD controller is actively connected under control of received processing instruction streams, thereby permitting each SIMD controller to be actively connected to a different number of processing units for different processing tasks.

摘要： A data movement controller (20) for controlling the movement between a shared data store (18) and a local data store (16) such that the data can be used by a plurality of parallel data processing elements is described. The data movement controller (20) comprises a set of data registers (56, 58, 60) which, in use, are loaded with different data parameters (57, 61, 62) to define a plurality of different ways in which data is transferred between the shared data store (18) and a set of processing elements (12). The data parameters (57, 61, 62) define a set of time delays for transferring portions of the data to predefined ones of the plurality of processing elements (12) and the type of overall data transfer that is to be carried out. The transfer of data in this programmable manner facilitates efficient use of the data movement controller (20) with SIMD associate processors (12) and in one example, the efficient processing of a stream of multiple-source digital data received at radio telecommunications base station to remove distortion due to multi-path effects.

摘要： Methods and apparatus for conducting motion searching are provided. Motion search is conducted by comparing an image macroblock against a plurality of positions within an image search region. A first 2D array comprises interconnected multi-directional shift registers for storing and shifting image values corresponding to a search window within the search region. A second 2D array comprises registers for storing image values corresponding to a macroblock. A distortion calculation module is operatively connected to the first and second 2D arrays, the distortion calculation module being arranged to calculate and output a distortion value corresponding to the difference between image values stored in associated registers of the first and second arrays, the distortion value thereby quantifying the correlation between the search window and the macroblock. The shift registers of the first 2D array are controlled to pass image values between adjacent shift registers to translate the position of the search window within the search region. Distortion values outputted after progressive shifts of the first 2D array are then tracked thereby determining an optimal registration position of the macroblock relative to the search region.
