Abstract
A Huffman Decoder is provided for decoding a data stream of fixed length and variable length codes and is adapted for video decompression applications. In the case of variable length codes, a table index calculation is performed using a ROM whose addresses are controlled by a selector/shifter. This calculation is bypassed in the case of fixed length codes. An index-to-data circuit then yields decoded data.
