Method of real time MPEG-4 texture decoding for a multiprocessor environment

摘要

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 for processing data independent The method preferably makes an assumption as to prediction 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 and for efficiently segmenting operations within a multiprocessing decoder.
