  • Patent number: 6473087
    Abstract: A method and system for concurrent processing of slices of a bitstream in a multiprocessor (MP) system is disclosed. The MP system includes a number of identical processors and a common memory. The memory is for receiving a plurality of bitstreams (preferably MPEG2 bitstreams) as a plurality of slices. The method and system comprises accessing a semaphore register by one of the plurality of processors and searching for an associated slice within the memory by the one processor. The method and system further comprises processing the associated slice by the one processor. Finally, the method and system comprises updating a memory location which holds the last address of the associated slice by the one processor; wherein subsequent processors search for each of the plurality of slices from the updated last address in the register. A system and method in accordance with the present invention provides for intercommunication between the plurality of processors within a multiprocessing system.
