Abstract
Method and apparatus for decoding Huffman encoded words are disclosed which include the use of logic gates connected in the form of a binary decoding tree which includes branches, interior and leaf nodes. Bits of the encoded word are sequentially supplied to gates of the binary tree. Simultaneously, gate enable signals are supplied to gates of the binary tree. Both the data bits and enable signals are supplied to gates at increasingly higher levels of the binary tree. When an output is obtained from a gate associated with one of the leaf nodes of the tree, the process of sequentially supplying data bits and enable signals to gates of the binary tree is repeated for the next encoded word. The original data words are regenerated by use of outputs from said gates associated with leaf nodes of the binary tree.
