Abstract
An apparatus to implement Huffman decoding in an INFLATE process in a compression engine. An embodiment of the apparatus includes a bit buffer, a set of comparators, and a lookup table. The bit buffer stores a portion of a compressed data stream. The set of comparators compares the portion of the compressed data stream with a plurality of predetermined values. The lookup table stores a plurality of LZ77 code segments and outputs one of the LZ77 code segments corresponding to an index at least partially derived from a comparison result from the set of comparators.
