Реферат: DECODING CIRCUIT FOR VARIABLE LENGTH CODES Abstract of the Disclosure A tree-structured network of substantially similar logic modules is used to decode butted variable-length code words. Bits of a fixed-length sample from a bit stream sample, which sample has length equal to the maximum allowed code word length, are applied in parallel to respective rows of the tree. When the codes have the prefix property, it is assured that only one row will generate an output at a terminal node. This output uniquely identifies the decoded symbol and, by virtue of its position in the tree, indicates the associated code word length and therefore, the beginning point for the next code word. - i -
