Abstract:
A data decompression apparatus for decompressing an input stream of codes to recover an output stream of data characters corresponding thereto, a code corresponding to a string of data characters, comprisingcode decoder means including a plurality of code decoder outputs corresponding to a respective plurality of codes to be assigned to strings, said code decoder means responsive to an input code for selectively energizing a code decoder output in accordance with said input code, a plurality of logic elements corresponding to said respective plurality of codes, a logic element having an input and an output, the inputs of said logic elements being coupled to respective code decoder outputs, character storage means responsive to the code decoder outputs and having a plurality of storage locations for storing respective data characters, a storage location being accessed by a code decoder output to provide the data character stored therein, and coupling means for selectively coupling outputs of said logic elements to inputs thereof so that the data characters of the string corresponding to said input code are provided by said character storage means, thereby providing said output stream of data characters.
