Abstract

Memory architecture provides capabilities for high performance content search. The architecture creates an innovative memory that can be programmed with content search rules which are used by the memory to evaluate presented content for matching with the programmed rules. When the content being searched matches any of the rules programmed in the Programmable Intelligent Search Memory (PRISM) action(s) associated with the matched rule(s) are taken. Content search rules comprise of regular expressions which are converted to finite state automata and then programmed in PRISM for evaluating content with the search rules. The PRISM memory provides features for complex regular expression symbols like range detection, complement control, bit masking and the like and enables complex symbols and compact regular expression representation.

Claims (4)

1 . A memory architecture comprising programmable intelligent search memory for content search wherein said programmable intelligent search memory performs regular expression based search wherein said regular expression comprises complex symbols.

2 . An integrated circuit chip comprising programmable intelligent search memory for content search wherein said programmable intelligent search memory performs regular expression based search wherein said regular expression comprises complex symbols.

3 . A hardware processor comprising an integrated circuit chip memory said integrated circuit chip memory comprising programmable intelligent search memory for content search, wherein said programmable intelligent search memory performs regular expression based search wherein said regular expression comprises complex symbols.

4 . An integrated circuit chip of claim 2 comprising a processor comprising memory, said memory comprising said programmable intelligent search memory for content search, wherein said programmable intelligent search memory performs regular expression based search wherein said regular expression comprises complex symbols.
