摘要： An embodiment may include first circuitry and second circuitry. The first circuitry may compress, at least in part, based at least in part upon a first set of statistics, input to produce first output exhibiting a first compression ratio. If the first compression ratio is less than a desired compression ratio, the second circuitry may compress, at least in part, based at least in part upon a second set of statistics, the first output to produce second output. The first set of statistics may be based, at least in part, after an initial compression, upon other data that has been previously compressed and is associated, at least in part, with the input. The second set of statistics may be based at least in part upon the input. Many alternatives, variations, and modifications are possible.

摘要： Techniques for decompressing a compressed input by determining, according to an ordering of allowable codewords, an offset for a variable length codeword detected in the input; accessing a record at the determined offset in a data structure having one record for each of the allowable codewords, each record including a portion for at least one of a literal value and a length value and a portion for a type value indicative of whether the record is for a literal or a length; and determining a decompressed output based at least in part on the accessed record.
