20230060654 · 2023-03-02 ·

Systems and methods are provided for mitigating effects of hash collisions in hardware data compression, for example reducing or avoiding the side effects of hash collisions, or reducing or avoiding slow downs caused by hash collisions. In an aspect, a processor-implemented method includes: hashing an input data byte sequence to produce a hash value, the input data byte sequence being located at a sequence address within an input data stream; and storing, in a hash table at a hash address corresponding to the hash value, the sequence address and a portion of the input data byte sequence. In an aspect, to further avoid hash collisions, hash memory accesses are distributed among a plurality of parallel hash banks to increase the throughput. Another aspect virtually extends a hash depth by extending a data match search around broken hash links, going backward in the data sequence.

Deflate compression using sub-literals for reduced complexity Huffman coding

A literal element that has a plurality of bits is received. The plurality of bits in the literal element is divided into a first sub-literal comprising a first set of bits and a second sub-literal comprising a second set of bits. The first sub-literal is encoded using a first Huffman code tree to obtain a first sub-literal codeword; the second sub-literal is encoded using a second Huffman code tree to obtain a second sub-literal codeword. Encoded data that includes information associated with the first Huffman code tree, information associated with the second Huffman code tree, the first sub-literal codeword, and the second sub-literal codeword is output.
