Abstract:
A method for operating a processor, comprising:receiving pixel data for an image array, at an input port of the processor; directing the pixel data through an arithmetic logic unit; performing in the arithmetic logic unit an on-the-fly compression process that converts the pixel data to compressed pixel data as the pixel data are input through the input port; storing the compressed pixel data in a buffer of the processor; searching the compressed pixel data in the buffer for a block of the compressed pixel data that best matches a compressed reference block; loading into the processor an uncompressed block of pixel data that corresponds to a portion of an image including an image area that corresponds to the block of the compressed pixel data that best matches a compressed reference block; and searching the uncompressed block of pixel data for a block of the uncompressed pixel data that best matches a reference block.
