Abstract
A system and method are disclosed that compiles a sub-expression associated with an inexact pattern contained in a regular expression into a plurality of microprogram instructions that can be stored in contiguous locations of an instruction memory. At least one of the microprogram instructions includes a next instruction address and a fetch length value, where the next instruction address indicates the instruction memory address of the next instruction to be executed and the fetch length value indicates the number of sequentially-executed instructions that are to be fetched from contiguous locations of the instruction memory.
