Abstract: A method implemented in a graphics engine for decoding image blocks to derive an original image is provided. The method comprises receiving at least one encoded image data block at a block decoder, the at least one encoded image data block comprising a plurality of codewords and a bitmap. The method further comprises determining a block type based on the plurality of codewords and selecting a decoder unit among a plurality of decoder units in accordance with the block type.
