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.

Symbol parsing architecture

A device comprises a plurality of interface circuits configured for communicating between a semantic processing unit and a memory and a selection circuit for selecting an interface circuit allocated to a semantic processing unit for processing a data operation request in the memory.

Arbiter for array machine context data memory

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.

Array machine context data memory

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.
