ABSTRACT:
A system that processes compressed data arriving in packets corresponding to picture blocks, the packets being separated by headers containing decoding parameters of the packets. A memory bus is controlled by a memory controller to exchange data between the processing elements and a picture memory. A pipeline circuit contains a plurality of processing elements. A parameter bus provides packets to be processed to the pipeline circuit, as well as the decoding parameters to elements of the system. The parameter bus is controlled by a variable length decoder that receives the compressed data from the memory bus and that extracts the packets and the decoding parameters therefrom.
