Abstract: Apparatus for supplying multiple, separately addressed data items from a data table in external memory. The apparatus comprises a cache memory (230) having n separately addressable memories banks organised as m cache-lines and n programmable address generators (1881) each coupled to a corresponding one of said n memory banks. The generators (1881) using an index to generate multiple addresses to simultaneously retrieve multiple data items from the memory banks. A data organizer (1892) positions the retrieved data in an output packet.

Abstract: 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.
