Abstract
A compiler/loader unit for a RegEx accelerator is described that receives a first set of regular expression rules for implementing the RegEx accelerator, generates, based on the first set of regular expression rules, an initial deterministic finite automata (DFA) graph, and generates, an initial memory map for allocating the initial DFA graph to a memory of the RegEx accelerator. The compiler/loader unit receives receive, a second set of one or more new or modified regular expression rules for implementing the RegEx accelerator and in response performs incremental compilation of the second set of regular expressions. The compiler/loader unit generates, based on the second set of one or more regular expression rules, a supplemental DFA graph and reconciles the initial DFA graph with the supplemental DFA graph to generate an updated memory map for allocating the initial DFA graph and the supplemental DFA graph to the memory of the RegEx accelerator.
