    摘要: A data buffer apparatus stores first data objects containing a plurality of first data items and second data objects containing one or more second data items in a number of different ways depending upon a mode of operation. The apparatus includes an encoder (1290) for rearranging the order of the first data items within the first data objects in accordance with first arranging mode, prior to storing in the buffer (1293). The apparatus also includes a decoder (1291) for rearranging the order of a plurality first data items read from the buffer, in accordance with a second arranging mode.

    摘要: A graphics processor performs graphical operations on graphical objects represented in an external data format. The graphics processor includes a setup unit, first and second mapping units, and a calculator. The setup unit sets up one or more registers reflecting a current instruction. The first mapping unit maps, responsive to the current instruction, the external data format to at least one corresponding internal data format selected from a set of internal data formats. The calculator performs graphical operations on the graphical objects when in one of the selected internal data formats. The second mapping unit maps, responsive to the current instruction, each internal data format in the set of internal data formats to the external data format after the graphical operations have been performed.

    摘要: An apparatus for converting an input image in an input color space to an output image in an output color space. The apparatus has a cache memory for storing from external memory, sparsely located output color values corresponding to input pixels closest to the current input pixel of an image stream, if not already present in the cache memory. The apparatus also has retrieval means for retrieving, from said cache memory, the sparsely located output color values corresponding to the current input pixel of the stream. The retrieved output color values are interpolated by interpolation means to derive an output color value in said output color space.

    摘要: A method (500) of generating a matching key (599) for an image (501) is disclosed. The matching key (599) is substantially invariant to rotation, scale and translation. The method (500) starts by forming a spatial domain representation of the image (501) that is substantially invariant to translation of the image (501). Rotation and/or scaling in the spatial domain representation is next transformed (580) into translation to form a transformed image. A representation of the transformed image is then formed that is substantially invariant to translation of the transformed image. The representation of the transformed image is the matching key (599) for the image (501).
