Abstract
Compression and decompression apparatus and methods for producing fixed-length compressed data blocks with variable-length compression are described. The compression system receives an N-bit word from a data block and determines the variable compression length for the word. A bit counter keeps track of the number of bits remaining and determines if sufficient bits have been used to ensure that the fixed-length compressed data block will be filled. If so, the compressed word is output. If not, prior to output the compressed word is padded with an appropriate number of bits, which may be null bits.
