  • Patent number: 6615210
    Abstract: The method for providing a “Don't Care” bit to improve the speed of information matching in a digital information processing system. After the match information is input, it will be divided into multiple sub-bit-streams and then input to a correspondent selector for obtaining the content of a selected memory bank. The output of each selector is forwarded to the product module to compute an unencoded match result. Finally, the priority encoder receives the unencoded match result and performs priority encoding to generate an encoded match result and a match flag. If the match flag is positive, it indicates that there is a hit in the rule table for the match information. Thus, the match result serves as an index for looking up an information table.
