Abstract
An assist processor operates in conjunction with a data path of individual hardware functional units to decode an MPEG-2 compliant data stream. The assist processor has the capacity to assist in processing specific blocks of data, assist in processing every block of data, or assist in processing only blocks of data with an indicator or flag or specific bit or byte set. The assist processor, when notified, modifies the operation of the functional unit or the data that it is operating on, and if necessary, returns the data to the datapath of the hardware functional units. The hardware functional units may operate as an MPEG-2 transport demultiplexor.
