  • Symbol parsing architecture
    Patent number: 7478223
    Abstract: A devices and method for parsing a data stream comprises a parser stack configured to store one or more parsing symbols, each parsing symbol representing a different state of data stream parsing, a table interface configured to retrieve one or more production rules from a production rule table according to the parsing symbols, and a state machine configured to control the parsing of a data stream according to the retrieved production rules.

  • Array machine context data memory
    Patent number: 7424571
    Abstract: A device performs lookup functions for a semantic processing unit. The device comprises a plurality of interface circuits for receiving data operation requests from the semantic processing unit. The device comprises a buffer for allocating an interface circuit to a semantic processing unit having a data operation request. A selection circuit, coupled between the plurality of interface circuits and a memory unit, selects an allocated circuit for accessing the memory unit to process the data operation request.

  • Parser table/production rule table configuration using CAM and SRAM
    Patent number: 7415596
    Abstract: A system and method for parsing a data stream comprises a production rule table populated with production rules, a parser table populated with production rule codes that correspond to production rules within the production rule table, and a direct execution parser to identify production rule codes in the parser table and to retrieve production rules from the production rule table according to the identified production rule codes, the direct execution parser is operable to parse a data stream according to the retrieved production rules.
