Abstract
(EN)

Briefly, within a computer or digital data processing system, embodiments describe a method, article and apparatus for compressing data is described, which may be used for communicating between two or more components connected to an interconnection medium (e.g., a bus) within a single computer or digital data processing system, and/or for communicating between two or more computers or digital data processing systems via an interconnection medium such as a network.
