摘要： A method and apparatus for performing a matching operation on data are disclosed. With an exemplary embodiment, a programmable logic device can be used to search for data of interest to an application, where the programmable logic device processes streaming data against a data key to generate a signal indicative of a similarity between the streaming data and the data key and compares the generated signal with a defined threshold to thereby determine whether the streaming data is deemed a match to the data key, wherein the threshold is adjustable to control whether the programmable logic device performs an approximate match operation or an exact match operation, and further to control, for an approximate match operation, a degree of approximate matches returned by the approximate match operation.

摘要： A method and device are disclosed for an associative and approximate, analog or digital scanning of databases that allows for the asynchronous accessing of data from a mass storage medium. The invention includes providing dedicated analog and digital circuitry and decision logic at the mass storage medium level for determining a key identifying the data of interest, continuously comparing the key to a signal generated from a reading of the data from the mass storage medium with an approximate or exact matching circuit to determine a pattern match, determining a correlation value between the key and the data as it is read in a continuous fashion, and determining a match based upon a preselected threshold value for the correlation value. The pattern matching technique eliminates any need to compare data based on its intrinsic structure or value, and instead is based on an analog or digital pattern. The key and data may be either analog or digital. This device and method may be provided as part of a stand-alone computer system, embodied in a network attached storage device, or can otherwise be provided as part of a computer LAN or WAN.
