    Abstract: In one embodiment, an apparatus comprises a first compression engine to receive a first compressed data block from a second compression engine that is to generate the first compressed data block by compressing a first plurality of repeated instances of data that each have a length greater than or equal to a first length. The first compression engine is further to compress a second plurality of repeated instances of data of the first compressed data block that each have a length greater than or equal to a second length, the second length being shorter than the first length, wherein each compressed repeated instance of the first and second pluralities of repeated instances comprises a location and length of a data instance that is repeated. The apparatus further comprises a memory buffer to store the compressed first and second plurality of repeated instances of data.

    Abstract: Methods and apparatus to perform string matching for network packet inspection are disclosed. In some embodiments there is a set of string matching slice circuits, each slice circuit of the set being configured to perform string matching steps in parallel with other slice circuits. Each slice circuit may include an input window storing some number of bytes of data from an input data steam. The input window of data may be padded if necessary, and then multiplied by a polynomial modulo an irreducible Galois-field polynomial to generate a hash index. A storage location of a memory corresponding to the hash index may be accessed to generate a slice-hit signal of a set of H slice-hit signals. The slice-hit signal may be provided to an AND-OR logic array where the set of H slice-hit signals is logically combined into a match result.

    Abstract: Methods and apparatus to parallelize data decompression are disclosed. An example method selecting initial starting positions in a compressed data bitstream; adjusting a first one of the initial starting positions to determine a first adjusted starting position by decoding the bitstream starting at a training position in the bitstream, the decoding including traversing the bitstream from the training position as though first data located at the training position is a valid token; outputting first decoded data generated by decoding a first segment of the bitstream starting from the first adjusted starting position; and merging the first decoded data with second decoded data generated by decoding a second segment of the bitstream, the decoding of the second segment starting from a second position in the bitstream and being performed in parallel with the decoding of the first segment, and the second segment preceding the first segment in the bitstream.

    Abstract: Detailed herein are embodiments of systems, methods, and apparatuses for decompression using hardware and software. For example, in embodiment a hardware apparatus comprises an input buffer to store incoming data from a compressed stream, a selector to select at least one byte stored in the input buffer, a decoder to decode the selected at least one byte and determine if the decoded at least one byte is a literal or a symbol, an overlap condition, a size of a record from the decoded stream, a length value of the data to be retrieved from the decoded stream, and an offset value for the decoded data, and a token format converter to convert the decoded data and data from source and destination offset base registers into a fixed-length token.

    Abstract: Technologies for efficiently compressing data with run detection include a compute device. The compute device is to produce a hash as a function of a symbol at a present position and a predefined number of symbols after the present position in an input stream, determine whether the symbol at the present position is part of a run, obtain, from a hash table, a chain of pointers to previous positions in the input stream associated with the hash, determine, as a function of whether the symbol is part of a run and to identify a matched string, a number of strings referenced by the chain of pointers to compare to a string associated with the present position in the input stream, and output, in response to an identification of a matched string, a reference to the matched string in a set of compressed output data.
