Abstract:
1. A multiprocessor decoder system comprising: a plurality of connected processors processing a set of data macroblocks, each processor having a first mode to generate and store an entropy decoding output for a data macroblock in an associated storage element and a second mode to retrieve and decode stored macroblock data from associated storage elements in response to a previously stored macroblock entropy decoding output, predetermined data from at least one adjacent macroblocks, and data from another connected processor; each processor in the second mode at least partially completing the decode of the stored macroblock data before enabling the next connected processor to operate in the second mode; each processor in the first mode generating an enable signal upon completion of the generation of the entropy decoding output to enable the next connected processor to operate in the first mode; and the last connected processor generating an enable signal upon completion of its processing operation in the second mode to shift the series of processors to the next set of data macroblocks.
