Abstract:
A data compression system outputting fixed-length block data, each block including a plurality of variable bit length data words, said system comprising:an input for receiving N-bit data words as input data to be compressed; a variable-length compressor coupled to said input for compressing said input data to variable length compressed data words having fewer than N bits, and having an output; a bit counter coupled to said output for counting the number of bits resulting from compression of a predetermined amount of said input data; and a padder for adding one or more bits to a plurality of said selected compressed data words as a function of said bit counting by said bit counter so as to reformat said predetermined amount of data into fixed-length block data for output, wherein said padder adds said one or more bits at the end of said selected compressed data words.
