ABSTRACT:
A digital data handling system handling display signal streams has a video processor which is capable of high performance due to vector processing and special addressing modes. The video processor is a single VLSI device having a plurality of processors, each of which has associated instruction and data caches, which are joined together by a wide data bus formed on the same substrate as the processors. Most audio and/or video compression algorithms use a Huffman style bit compression scheme with compression codes in variable length bit fields. The compressed data is a compacted bit stream which must be interpreted serially in order to extract the codes. In contrast to most microprocessors which process bit streams only inefficiently, the present invention uses a serialization FIFO to provide a hardware assist to the Huffman encoding/decoding.
