Abstract
An NFA (Non-deterministic Finite Automaton) circuit includes a hardware byte characterizer, a first matching circuit (performs a TCAM match function), a second matching circuit (performs a wide match function), a multiplexer that outputs a selected output from either the first or second matching circuits, and a storage device. N data values stored in first storage locations of the storage device are supplied to the first matching circuit as an N-bit mask value and are simultaneously supplied to the second matching circuit as N bits of an N+O-bit mask value. O data values stored in second storage locations of the storage device are supplied to the first matching circuit as the O-bit match value and are simultaneously supplied to the second matching circuit as O bits of the N+O-bit mask value. P data values stored in third storage locations are supplied onto the select inputs of the multiplexer.
