Handling complex regex patterns storage-efficiently using the local result processor
Abstract:
A result processor access a result table for an entry associated with a predetermined sub-expression of a regular expression in response to a finite state machine finding the predetermined sub-expression in the input stream. The result processor executes an instruction associated with the entry, the instruction including one or more operations to be performed on one or more bits in a bit vector register, and determines as a function of the one or more bits in the bit vector register whether the complex regular expression has been found in the input stream.
