ABSTRACT:
An apparatus and method is described for performing texture-decoding within a video decoder processing a series of macroblocks within a video bit-stream. The inventive texture decoding is particularly well suited for implementation within decoders incorporating multiple processors. The method separates data independent operations from data dependent (sequential) operations wherein multiprocessing may be efficiently utilized for processing data independent macroblocks. The method preferably makes an assumption as to prediction direction within the set of data dependent operations. A prediction determination is then made and the assumption corrected if necessary with a transposition within the data independent operations operating on the macroblocks. The method reduces the computational overhead and provides for efficiently segmenting operations within a multiprocessing decoder.
